9500 MPR can operate in Hybrid or Packet Mode with same hardware
Enabling possibility for smooth migration from Hybrid mode to Packet mode
9500 MPR in fact is a packet-based solution designed to address in native way networks where
packet based traffic is predominant, nevertheless supporting the still present TDM/ATM traffic, which
remains vital. 9500 MPR represents the solution to allow smooth migration from the TDM world to
the packet domain in the Mobile Backhauling networks. The different incoming traffics are
converted into Ethernet packets before sending them to the internal Ethernet switch, the packet
overhead on E1 /STM-1 being removed before sent in the air.
As capacity grows in the access, the requirement for higher bandwidth support will be needed in the
backhaul as well as in the metro network. Alcatel-Lucent target to address metro networks
requirement with a carrier Ethernet based solution combined with microwave packet transport. The
result in the long run is a change in the backhaul from PDH links to carrier Ethernet and in the Metro
from SDH to carrier Ethernet packet rings, and eventually to mesh networks. Exploiting the benefits
5
of packet architecture vs. circuit architecture (Multiservice aggregation, Service awareness, adaptive
packet transport) in accommodating broadband services, 9500 MPR allows the access equipment to
smoothly evolve in line with the new technology and related protocols (ATM/TDM/Ethernet) without
the need of renewal of an existing microwave site and protecting the already made investments.
9500 MPR is based on two separate elements:
the MSS, an indoor service switch that can also operate as a stand alone site aggregator
a) the multipurpose ODU, the MPT, open to be managed in the following operating
modes:
Split-Mount mode in conjunction with MSS
Standalone mode (for native Ethernet applications) connected directly to any
switch/router/base station
9500 MPR Node supports a mix of non-protected and protected or diversity operation for single link,
repeater or star radio configurations.
The core platform, MSS1/4/8, with multiplexing & symmetrical x-connection functions, is able to
manage different radio directions, with the possibility to add-drop tributaries in case of local
PDH/SDH/ATM/Ethernet accesses. Core platform is based on packet technology (Ethernet Switch)
with a generic interface serial 16 x GETH between Core and peripherals.
The peripherals currently available are:
6
- 32 ports E1 card for PDH applications
- 16 ports E1 card for native ATM/IMA applications
- 2E1 SFP for few E1s connectivity
- E3 SFP for E3 connectivity
- AUX card for auxiliary channels and station alarms collection
- 2 ports STM-1 card for SDH applications
- EoSDH SFP for Ethernet over SDH applications
- Ethernet Access switch card providing 8GE i/F
- Fan unit
The Outdoor Units are connected to the MSS, through one of the following interfaces:
- One port of the Core Board
- One port of MPT Access card
- One port of EAS card
Industry-leading scalability and density is provided in the 9500 MPR, supporting a two rack unit MSS-
8 (2 RU) or a one rack unit MSS-4 (1 RU) or an half rack unit MSS-1. The MSS-8 has eight slots, MSS-4
has four slots, MSS-1 is a pizza box; in MSS 4 and 8 cases, two are allocated for core cards (control
and switch module), with the remaining six (or two) being available for user traffic adapter cards
(PDH access card, SDH Access Card, ATM access card, Auxiliary card) or for radio card (modem, MPT
Access Card, AWY Access Card). Each of the adapter card slots can be used for any adapter card type,
removing the burden of complex pre-engineering and future scenario planning.
9500 MPR tail supports a mix of non-protected and protected or diversity operation for single link.
For tail applications, the MSS-1c is able to manage up to 2 radio directions, with the possibility to
add-drop tributaries in case of local PDH/Ethernet accesses. MSS-1c is based on packet technology
(Ethernet Switch) with a max capacity of 5 Gbps. MSS-1c is a half width, one rack unit, offering a
compact and cost optimized solution.
The Alcatel-Lucent 9500 MPR has a compact, modular architecture, constructed to allow flexible use
of line adapter cards so operators can optimize the configuration to meet the specific requirements
of a site. With the modular architecture comes additional resiliency and flexibility. The solution can
optionally support 1+1 fully redundant configuration with core cards, PDH /SDH cards and radio
access cards; each type of card can be redundant independently. Full-protected configuration is
available, including EPS, RPS hitless, HSB and Core module protection.
7
9500 MPR together with all other Microwave and Optical transmission Network Elements is fully
integrated into 1350 OMS Network Management System providing all the tools required operating
the network. 9500MPR is also managed by the 5620 SAM broadband manager shared with the
Alcatel-Lucent IP product portfolios to provide full management and provision of the network at
service level.
1.1 Working Modes
9500 MPR provides, with a unique type of HW, two SW (Operational Systems) each one with its own

1.3 MPT
2.1 Multipurpose radio
The innovative outdoor unit design of MPT, with GbE standard interface, opens the way to optimized
cost solution in the backhaul network.
MPT is a unique radio capable with the same hardware to be used:
- in standalone configuration (i.e. w/o dedicated indoor units), particularly useful in tail sites enabling
direct interconnection to Base Stations. In this configuration the equipment is called MPR-e.
- in split-mount configuration with MSS indoors
The MPT is a Multipurpose Packet Radio that converts an Ethernet signal into a Radio signal; it
performs not only IF/RF functionalities, but hosts the modem section too. The input interface is a
standard Giga Ethernet interface (electrical or optical).
Ethernet traffic coming from MSS or from any GEthernet generic device (base station, router,
switch..) is transported to MPT through optical or electrical connectivity.

3 Connectivity options
In case of electrical connectivity, indoor/outdoor distance up to 100m,a single CAT5 cable connects
an MPT to the MSS, or the GEthernet generic device.
In case of optical connectivity, two cables connect an MPT to the MSS or GEthernet generic device:
one cable is a 50 ohm coaxial cable to send the -48 V power supply to the MPT; the second is an
optical cable.
4 Frequency availability
MPT covers the full range of frequencies from 5.8 GHz to 38GHz and 70/80 GHz, including 60 GHz.
5 XPIC
Thanks to XPIC function, MPT can provide twice the capacity in one frequency channel ( Co-channel
Dual Polarized) for any combination of Ethernet, PDH and SDH up to 1Gbps.
This is very useful when access to frequency channels is limited.
Two different configurations of “traffic management” are available:
Configuration by default: traffic flows statically configured and separated by the user.
Operator can segregate the two radio interfaces.
In case of LAG, the mechanism is hashing the data flow. In case of hardware failure all the
traffic is redistributed to the working radio and traffic dropping is performed according to
QoS. LAG in conjunction with XPIC is providing both capacity increase and protection of the
high priority traffic
MPT being a multipurpose radio, ALU implemented an innovative solution to allow XPIC upgrade.
MPT-HC is capable to be upgraded in XPIC in field thanks to a dedicated module directly integrated in
the outdoor unit.
Adaptive Modulation (from 4QAM to 256QAM) is a working mode supported in conjunction with
XPIC . Several configurations are available:
2x(1+0) XPIC configuration : 2 MPT-HC interconnected together with XPIC cable. This
configuration allows operating simultaneously two links on the same radio channel, with one
using the vertical polarization, the other one the horizontal.
16
Double 1+1 HSB XPIC : this configuration allows to protect 100% the traffic loaded on
polarization H and V in case of failure.
Double 1+1 SD HSB XPIC : same configuration as before with 2 antennas.
6 Throughput Packet Booster
The fundamental objective behind the Alcatel-Lucent packet throughput boost feature on the 9500
MPR is to maximize the amount of traffic payload that traverses a link. This action is done by
reducing the proportion of overhead required to transmit the payload. As most microwave links are
point-to-point in nature and are not shared resources, there is significant opportunity to reduce
unnecessary overhead. If we examine the content of a data packet, as shown in figure below, it is
sometimes surprising to see the amount of overhead when compared to the actual user traffic
contained in the IP payload field. The overhead fields are needed for routing, collision, and flow
identification in complex topology LAN/WAN networks. But in a point-to-point radio link with full-
duplex transmission where the medium is not shared by simultaneous users, overhead can be
drastically reduced to improve and increase overall throughput over the air.
Significant benefits can be gained by reducing packet overhead, especially when small packets are
considered. Let’s take a look at each of the header fields in the basic Ethernet frame .The first two
fields, Interframe Gap (IFG) and preamble, are not transmitted over the air and therefore not needed
in a microwave transmission, so automatically 20 bytes can be entirely eliminated per Ethernet
frame.
• Interframe Gap (12 bytes). Ethernet devices must allow a minimum idle period between
transmissions of Ethernet frames known as the Interframe Gap. IFG was introduced by IEEE
802.3 to avoid collision over a shared medium, such as the LAN.
• Preamble and Start of Frame Delimiter (8 bytes). These fields were added to the IEEE 802.3
standard to allow devices on the network to easily detect a new incoming frame. The
remaining fields that are subject to compression but not automatically eliminated are:
• Ethernet header (14 bytes). This is the information used to switch an Ethernet frame
17
across a network segment:
- Destination addresses (6 bytes)
- Source addresses (6 bytes)
- 802.1Q tag (4 bytes): Optional virtual LAN (VLAN) tag
- EtherType/length (2 bytes); EtherType is a two-octet field in an Ethernet frame. It is
used to indicate which protocol is encapsulated in the payload of an Ethernet frame.
• Payload (46-1500 bytes): Contains user data and/or IP/Multi-Protocol Label Switching
(MPLS) frames
We have seen that the IFG and preamble are not needed for microwave transmission, but how
significant is that? Visualizing the typical throughput gain achieved with microwave transmission
when compared to fiber may help. The highest gain occurs with smaller packets, so let’s take an
example where the Ethernet message is 64 bytes long, and the physical capacity transmission limit is
350 Mb/s.
• When the message is transmitted over fiber with one VLAN present, the frame carries
only 42 bytes of useful payload information but requires 84 bytes overall for transport
as it requires the IFG and preamble. As a result, 100 percent of the overhead must be
transported along with the payload.
• For the same physical capacity transmission limit of 350 Mb/s and 64 byte Ethernet
message over microwave, 20 bytes do not need to be transmitted. This results in about 100
Mb/s more data that can be transmitted with this Ethernet frame size, as shown in Figure 2.
All microwave vendors can boast to this level of header suppression, but Alcatel-Lucent improves
microwave header compression.
With the transition to LTE, another opportunity arises for optimizing payload across a radio link. LTE
deployments will increasingly use IPv6 packets, where additional header overhead is encapsulated in
the Ethernet payload. IPv6 IP addresses occupy an additional 32 bytes, making the transport
18
efficiency of multi-protocol packets of short length very poor. Header compression can significantly
increase radio link throughput by reducing protocol header overhead. The header size that is
compressed is constant, while the packet payload is variable. The greater the compression, the more
gain achieved for payload capacity. Header compression is most beneficial when small packets are in
the network, and when protocols like IPv4 or IPv6 are used. But not all packets are small. Internet
Mix or IMIX is a term used to describe typical Internet traffic passing through network equipment
such as routers or switches. When measuring equipment performance using an IMIX of packets, the
performance is assumed to resemble what could be observed if that equipment is deployed in a real
network. A typical traffic mix, adopted in the industry to test IPv4 performance and one that is
considered to be a good example of the traffic to be found in a mobile backhauling network, is shown
in Figure. Smaller packet sizes typically contain voice and larger packet sizes data.
Using the IMIX packet distribution, with 56 MHz 256QAM modem profile, and the physical capacity
transmission limit of 350 Mb/s, the following figure shows the amount of throughput gained by using
the Alcatel-Lucent packet throughput boost feature when compared to standard IFG and preamble
microwave suppression.
19
The light blue bar represents microwave with standard 20 byte suppression, and the dark blue bar
represents throughput capacity gained with Alcatel-Lucent packet throughput boost feature, which
also includes IFG and preamble suppression. As you can see, there is significantly more throughput
gained using packet throughput boost header compression when compared to the standard
microwave gains achieved with IFG and preamble suppression.
Alcatel-Lucent 9500 MPR header compression is implemented without any compromise to existing
features. With packet microwave, there is no change in Packet Delay Variation (PDV) values or
increase in latency. The Alcatel-Lucent 9500 MPR implementation is unique in that it does not use
additional buffers, which would introduce delay. With the Alcatel-Lucent packet throughput boost
feature, operators gain the most capacity with the highest availability.
As summary, with the Alcatel-Lucent packet throughput boost feature, operators can transport up to
1 Gb/s of traffic on a single channel. Under the most favorable conditions, the gain achieved by the
9500 MPR exceeds 300 percent, with an average that is often beyond 150 percent.
7 MPR-e
MPR-e is a new concept of radio outdoor radio.
Current MPT radio thanks to its GEthernet interface and its modem has a full flexible architecture
capable to support either split-mount architecture and stand alone architecture.
This flexibility is minimizing drastically the number of spare MPT and allowing to operator to change
his network topology based on the same hardware (full outdoor can become split-mount or the
opposite). Any GEthernet generic device (base station, switch, router..) will become capable to
transmit traffic other the air.
The Ethernet traffic is transmitted over the radio channel according to the configured QoS and to the
scheduler algorithms.
8 MPR-s
Until recently, the design and form factor of wireless backhauling solutions were not of great
importance to Service Providers, since they were typically mounted on high masts and unlikely to be
20
seen from ground level. This concept is currently changing with the new Metro Cell and Small Cell
network designs being rolled-out. Metro cells are being moved much closer to the ground,
sometimes almost down to street level, e.g. on top of low buildings or light poles/lamp standards.
Moving communications equipment this close to the public means that installing a large traditional
microwave to backhaul these BTS would simply not be an option. MPR-s has been introduced to
cover the metro cell backhaul with small form factor full outdoor radios.
MPR-s also provides the following connectivity options:
• Sub-6 GHz NLOS/nLOS licensed and unlicensed, options that can support up to 250 Mbps in
point-to-point, or point-to-multipoint, configurations.
• 60 GHz unlicensed LOS options that can support 1 Gbps capacity.

25
1.6 Ethernet Access Card (EAS)
In case more than 6 local Ethernet access are needed (that are built-in in the core card), 8 GE ports
An embedded 10 Gbit/sec L2 switch is present on the card.
There are 4 Electrical 10/100/1000 base-T electrical ports and 4 optical SFP (LX and SX).Supported features:
IEEE 802.1D User Selectable QoS : none, DiffServ or 802.1p bits VLAN management 802.1Q Q-in-Q IEEE 802.1Q Port segregation Flow control 802.3x Auto-negotiation enable/disable Support of jumbo frames (9728 bytes) on FE/GE interfaces Per port policer Per flow policer Broadcast/Multicast storm control MAC address control list VLAN swap
EAS card can be used optionally as interface card to interconnect up to 4 MPTs; supporting up to 24
MPT with a single MSS8.
Additionally, EAS card supports Multichannel LAG L1 feature. Multichannel feature provides a
solution where more traffic capacity is needed than can be transported over one physical link. N
26
radio links are aggregated to provide one logical link with a capacity that is the sum of the individual
links. This feature is particularly useful for wireless transmission systems where multiple radio links
must be used in parallel to achieve very high capacities of 1Gbit/s and above. This provides optimum
payload balance, regardless of the throughput demands of individual user connections
Redundancy is also a feature of multichannel aggregation. If a link is lost, its traffic is directed onto
the remaining link(s) within the group.
If the Ethernet bandwidth on the remaining link(s) is over-subscribed, traffic will be dropped, though
with appropriate QoS settings only low priority data will be affected - all high priority data will
continue to get through.
Multichannel feature can be applied in principle to any kind of traffic: Ethernet, TDM, ATM and SDH.
Multiline feature is supported by EAS 8 Gbit/card, with MPT-HC connected to optical ports.
LAG groups can be IntraEAS (all MPTs on same EAS card) or CrossEAS (MPT on EAS on the same Row);
here below some example of supported configuration. Maximum number of MPTs in a LAG group is
4.

1.7 2E1 SFP
In order to target applications where a few number of E1s are needed, a miniature E1 over GE
converter is available. 2E1 SFP is SFP device that provides two G. 703 E1 interfaces, supporting the
same functionalities of 32E1 PDH card. In addition, this device is able to generate a “dummy framed”
E1 in order to provide synchronization to an external equipment (like a BTS).
This device can be used instead of 32E1 PDH card when the requested E1 connectivity is limited,
saving in this way one slot in MSS4/MSS8 that can be used by other cards.
2E1 SFP
2xE1 SFP can be plugged in one of the two SFP ports of Core card, providing two G. 703 E1 interfaces
(up to 4xE1 in case Core Card hosts 2 SFP). EPS protection is available in case Core Card is protected:
the secondary SFP is hosted by the stand-by Core, and a Y cable is provided to connect the 2 SFP.
E3 SFP is a TDM Pseudo wire access gateway extending TDM-based services over packet-switched
networks.
E3 SFP
The device converts the data stream from its user E3 interface into packets for transmission over
9500 MPR network; the addressing scheme is MEF8. These packets are transmitted via the SFP port
of the Core Board; a remote E3 SFP converts the packets back to TDM traffic.
Physical interface is 1xE3 electrical in a SFP cage with 1.0x2.3 connector.
E3 SFP can be plugged in one of the two SFP ports of Core card (up to 2xE3 in case Core Card hosts 2
SFP.
EPS protection is available in case Core Card is protected: the secondary SFP is hosted by the stand-
by Core, and a Y cable is provided to connect the 2 SFP.
34
1.12MPT Access Card
The MPT Access Card is dedicated to connect the MPT to MSS,.
Up to two MPT can be connected to the MPT Access Card
Main physical characteristics:
2 x 10/100/1000 Base – T Port for electrical data to/from MPT. These ports can also
power the MPT through the same CAT5 cable.
2 x SFP Optical GETH for optical data connectivity to/from MPT
Double 50Ω QMA Connectors as an option for MPT Power feeding in case of optical
connectivity
Main Functions:
o Provide traffic interface between Core switch and MPT
o Provide the power supply interface to the MPT
o Lightning and surge protection for both electrical GETH and power interfaces that are
connected to MPT
o MPT 1+1 protection management
o Clock distribution function
o Radio Link Quality notification through MPR Protection Protocol frames
35
MPT Access Card
o Communication with Core controller for provisioning and status report.
36
1.13Power injector plug-in
This card can be used for several applications:
When MPT is connected to CORE, power injector is needed to provide power to the MPT
at optimized price
When MPT is used in stand alone (MPR-e) and connected to 7705SAR, Power injector
plug-in can be used inside 7705 chassis to power MPT
A box version is also available for all other applications of MPR-e.
Main physical characteristics:
2 DC connectors in the front (box), or power from the backpanel.
2 RJ45 for the data in
2 RJ 45 for the data + DC out
2 LEDs indicating the presence of DC voltage on each Ethernet output
Power injector plug-in
37
1.14AUX board
Service channels accesses and housekeeping alarm are supported by auxiliary peripheral.
Auxiliary cards support two main functions:
Auxiliary data channels management (2 x 64 Kbit/s service channels)
External I/O management
AUX Board
Auxiliary board front panel is equipped with four connectors:
EOW connector
Service channel interface #1 (RS422 V11 DCE 64 kbit/s)
Service channel interface #2 (RS422 V11 DCE 64 kbit/s)
Housekeeping interface (6 inputs + 7 outputs. The polarity of each alarm is user configurable
and a user defined label could be added per each alarm)
Only one auxiliary card per NE can be equipped, and in a fixed position: it can be lodged in slot 8
(bottom right) of MSS-8 or in slot 4 (bottom right) of MSS-4.
Typical applications for AUX board are :
transport over MPR of the ingress service channels that could be delivered for example by
9400 LUX 40/50, LUX12, 9400AWY 2.0/2.1, 9500 MXC
38
transport over MPR of the ingress service channels that could be delivered by end user. Note
in case of 64 Kbit/sec the end user must be always configured as DTE.
transport over MPR of the TMN signal coming from:
o LUX 12, V11 9.6 Kbit/s RQ2 protocol
o LUX 40/50, V11 9.6 Kbit/s SNMP protocol
Please note that in the last case MPR is taking care of pure transport; no termination of TMN channel
is done inside MPR using aux card, while recommended TMN chain is done using Ethernet TMN
interface for 9400AWY and 9500 MXC.
39
1.15Fan BoardA FAN card is required inside the MSS-4/8 shelf. MSS-4 can be optionally equipped without fan card,
supporting temperature up to +45°C 1. The FAN holds three long-life axial fans, which are controlled
and performance-monitored by the controller.
Fan Board
To have high reliability 3 fans are used with separate alarms in order to understand the urgency (two
or three fans failed) or the not urgency condition (one fan failed).
The Unit is inserted from front side to avoid payload interruptions in case of fan maintenance. The
FAN is hot swappable and in-service replacement doesn't affect traffic.
An optional Fan unit, called Fan Alarm Card, is available on MSS-8, hosting a housekeeping connector
for Equipment Alarms (Summary, Major and Minor) and 4 housekeeping inputs and 8 high reliability
fans. The board is mandatory when 24V DC converter is equipped.

1.16+24V integrated DC/DC converter
An optional +24V DC/DC converter is available for MSS-8 shelf
One or two converters are able to slide on the MSS chassis, side by side, in a single card slot.
Unprotected converter kit will be used in configurations where single, non –redundant “A” battery
feed is used. Protected converter kit will be used when dual, redundant, “A” and “B” battery feeds
are used. In either configurations, the +24VDC to -48VDC converter kits use a single vacant slot of the
MSS chassis.
There is no interconnection between the converter(s) and the MSS backplane. Both the +24 VDC
input and -48 VDC output are available via 2 position connectors on the front of the unit.
The converter(s) will receive its input(s) from +24 VDC primary power feed(s) and the -48 VDC
output(s) will be connected to the MSS -48 VDC inputs located on the right side of the MSS chassis
via a short external power cable, providing -48 VDC to the MSS, in the same way the shelf is powered
when -48 VDC primary is used as oppose to +24 VDC.
+24V DC/DC converter can power any module in the shelf (and of course related ODU connected to
the module) up to a total power consumption of 348 watts.
When + 24V DC/DC converter is used, the Fan Alarm board must be equipped in the rack.

6Radio Configurations
The following configurations are available for each radio path.
1+0
In this configuration the radio chain consists of:
One Radio Outdoor Unit (MPT) One Antenna One MPT Access Card
1+1
In this configuration the radio chain consists of:
Two Radio Outdoor Units ( MPT) One or two antennas One or two MPT Access Cards
Following options are available for protected configuration: Hot Stand-by (with or w/o coupler) Frequency Diversity Polarization Diversity
1+1 Hot Standby
This method offers protection against HW failures providing two independent TX/RX chains. In (1+1)HSby one transmitter is working, while the other one is in stand-by; both receivers are active and the best ODU source is selected.
78
(1+0)
ODU 300/MPT
Modem/AWY/ MPT Access Card
In case of 1+1 Hot Stand-by on single antenna, both Radio Units are connected to a coupler, balanced or un-balanced.
Alternatively, in case of 1+1 Hot Stand-by Space Diversity, each Radio Unit is connected to an individual antenna.

Modem/MPT Access Card
This method offers protection against selective and temporary link quality degradation.
In (1+1) Frequency Diversity, both radio paths are active in parallel using different frequencies; this
method, based on memory buffer that guarantees the bit to bit alignment, can offer error free
protection against fading (via a hitless switch) up to 100dB/sec.
Both two antennas and single antenna (dual polarized) mounting arrangements are available.
(However, with FD, the usual arrangement is one antenna SP.)
(1+1) Polarization Diversity adopts the same concepts of FD, but in this case the same RF signal is
transmitted on two different polarizations (H/V) by means of a single double polarized antenna.
Adjacent Channel Alternate Polarised (ACAP), Adjacent Channel Co Polarised (ACCP) and Co-Channel
Dual Polarisation (CCDP) operations are supported
6.16.1
Antenna Mount
Direct-Mounted Radio Unit
The Radio Unit is attached to its antenna by a direct-mount collar, which includes a built-in rotator
for selection of vertical or horizontal polarization.
A full range of direct-mount antennas is offered with diameters from 0.3m to 1.8m. As an aid to
antenna alignment, the ODU includes receive signal level (RSL) access

Remote-Mounted ODU
Radio Unit can be installed separate from its antenna, using a remote-mount to support the ODU,
and a flexible-waveguide to connect the Radio Unit to its antenna.
A remote mount allows use of standard, single or dual polarization antennas. The mount can also be
used to remotely support a protected MPT pairing installed on a coupler. The coupler connects to the
remote mount assembly in the same way as a Radio Unit
6.2 Couplers
A coupler is used to connect two ODU to a common antenna for protected or single antenna
frequency diversity operation. Two versions are available, an equal-split 3/3dB coupler, and an
unequal-split coupler with a nominal 1dB insertion loss to/from the main ODU, and 10 dB insertion
loss to/from the standby ODU

10-11-38GHz MPT Coupler
6.3 Ortho-Mode Transducers (OMT)
Using one OMT and two MPT, it is possible to have double polarization (DP) configurations with
integrated antennas. With OMT we are offering the most compact and cost effective solution for
double polarization applications.
An OMT is a kind of double polarization coupler. The frequencies can be different (in a same band) or
identical (XPIC). By means of an interface, it is attached to the back plate of the antenna’s circular
waveguide feeder. This interface allows the rotation of the feeder for proper alignment of two facing
DP antennas.
There are two OMT shapes depending on the frequency band, identical to couplers:
82
Insertion loss from antenna to ODU is 0,5 dB, return loss 18 dB, Cross-polar discrimination (XPD) 30 dB, Inter-port Isolation (IPI) 35 dB.
6.4 4+0 or 2x(1+1) HSB dual pol integrated coupler
Mainly for N+0 configurations, a 3+0/4+0 dual pol integrated coupler is offered.
.
It is a very compact solution, allowing the usage of integrated antennas and avoiding the usage of
not-integrated antennas with external couplers and flex twist.

7MPT-GC Technical description
An MPT-GC link consists of two radio terminals that transmit to each other on a full duplex channel pair, providing point-to-point Ethernet and/or SONET/SDH connectivity between two locations.
The ODU is connected to indoor equipment through fiber for GbE connection. Power must be provided to ODU through a separate cable.
Each MPT-GC unit contains up to four SFP ports available for SONET/SDH and four SFP ports plus one copper RJ-45 port available for Ethernet. Any combination of ports can be used to carry traffic across the link.
The Ethernet interface traffic is bridged across the link via an embedded switch. The SONET/SDH traffic is handled separately within the radio and does not pass through the internal switch.
The SONET/SDH and Ethernet traffic are aggregated within the radio unit for transmission overthe air to the far end of the link. The portion of the radio bandwidth that is not used by enabled SONET/SDH interfaces is available for use by the Ethernet interfaces.
Depending on configuration the available Ethernet bandwidth can exceed 1000Mbps.
Frequency AgilityMPT-GC offers the flexibility to be tuned across the entire 80 GHz spectrum (71-76GHz & 81-86 GHz) in accordance with ECC REC 05/07.
