Fiber

efore the bandwidth explosion that was brought

on by the Internet, the proliferation of intranets,

and other graphics-heavy applications, the use of

fiber optic technology was often stifled by the cost

considerations involved in laying fiber to replace

the existing copper plant. Almost overnight,

exponential increases in demands for

broadband access increased the

feasibility of fiber as an access

medium. This is particularly true

since, compared to fiber, copper-

based DSL technologies do not

meet businesses’ immediate

demands for bandwidth and range.

The natural benefits that are part

and parcel of fiber – data security,

noise immunity and longer range –

make it an ideal long-term investment for

carriers creating

a new infrastructure or for those deploying a

telecommunications infrastructure in a new area.

At the same time that fiber is moving from the backbone

to the Local Loop, it brings with it technology such

as wave division multiplexing (WDM) that increases

the capacity of data transmission over fiber optic

cables all the way to corporate customers in

need of high bandwidth.

RAD Data Communications is a

recognized leader in developing

access equipment that helps bring

fiber optic solutions for the Local

Loop up to the customer premises.

These include multiservice access

nodes, ATM NTUs, multiplexers,

and of course, RAD’s full range

of fiber optic modems.

The following applications, based on projects

already using RAD’s fiber optic products, demonstrate

the versatility and ingenuity of RAD’s fiber optic

access solutions.

RAD’s solutions, which are the basis forthe preceding applications, surpass thecurrent needs of fiber optic networks.They represent a dynamic beginning ofthe possibilities for fiber optic deploymentin the world of telecommunications.

Future developments based on fiber optictechnology are expected to be responsesto the global proliferation of broadbandapplications, such as multimedia residentialservices, telemedicine and distancelearning. Continued growth in worldwidetelecommunications can be expected toencourage a further explosion in the needfor bandwidth and switching speeds.Following Fiber-to-the-Curb (FTTC), Fiber-to-the-Home (FTTH) is the next step inthe universal accessibility of fiber optics.In fact, it is already available in somecountries.

Within the first few years of the newmillennium, we can expect a move towardsPhotonic Superhighways, where opticalsignals will replace electronic signals andthe bandwidth will be much higher thanwhat is currently available, thus eliminatinginformation “traffic jams.“ Backboneswill become more powerful, with accesscapable of delivering high-speed servicesall the way to the customer premises. Andof course, it can be expected that theseimpressive improvements will eventuallyoffer more affordable broadband services.

Sophisticated new services can beexpected to take their place in thetelecommunications marketplace oftomorrow. With a solid track record inthe development of access solutions,RAD Data Communications will remainan industry leader in supporting futurefiber optic technologies.

Despite the relatively short distances involved in campusapplications, there are sufficient reasons to consider fiberoptic connectivity. When combining high speed traffic on asingle link, fiber gives more bandwidth than copper and ismore secure. In addition, fiber is an obvious choice to ensureimmunity from industrial electrical interference or protectionfrom lightning.

For straightforward point-to-point connections, RAD offersmultiplexers that combine a variety of interfaces into a single

fiber optic link. Included are the Optimux family, whichsupports multiple E1/T1 lines and/or Ethernet LAN ports.The Kilomux-2100 E1/T1 sub-rate multiplexer and theMegaplex-2100 multiplexer support any combination ofanalog voice, digital PBX, data and LAN traffic.

For single port solutions, RAD offers both miniature and fullsize modems with optional built-in Ethernet bridge ports. ForLAN-to-LAN applications, RAD also offers the TinyBridge forEthernet and the AMC-101 for Fast Ethernet connectivity.

Optimux multiplexers transport

multiple E1 or T1 links and

Ethernet up to 75 km (47 mi)

over a fiber optic link. They also

feature an optional redundant

optical link and SNMP central

network management.

This solution is based on the Optimuxand/or Megaplex multiplexers linked toRAD’s LRS-24 modem rack, which islocated at the central office or point-of-presence. Multiple services from a singlecustomer or multiple customers areconsolidated at the customer premises,ensuring that the bandwidth over thefiber optic link is utilized most efficiently.A fiber optic modem at the central officeenables direct transmission of theconsolidated traffic over the network.This makes the solution moreeconomical by preventing the need foranother multiplexer in the central office.In addition, this solution requires fewer

ports at the transport node’s SDH/SONETadd-drop multiplexer (ADM), whichleads to further savings.

A crucial part of this application isintegrated management functions, whichare embedded into all of RAD’sintelligent fiber optic products. The samefiber cable is used for data transmissionand in-band management information.

With high speed links serving numerouscustomers, availability of service iscritical and is enhanced by redundancy,which is an option in RAD’s high speedfiber optic products.

RAD’s ACE-101, located at the customerpremises, functions as either an ATMNTU or an Interworking NTU. Whendeployed as an A-NTU, it supports allstandard ATM rates (E1/T1, E3/T3 andSTM-1/OC-3c). When it is deployed asan I-NTU, it supports Ethernet, FastEthernet and E1/T1 CES ports as well.The ACE-101, equipped with a standardSTM-1/OC-3c port, can be connecteddirectly from the customer premises toan ATM switch at the central office.In order to deliver ATM services, it ispossible to use a fiber optic modem atthe central office, which works oppositethe ACE-101, with an E3/T3 fiber opticport. This is useful when there is anE3/T3 electrical port at the ATM switch.This configuration is more economicalbecause of the lower cost of electricalE3/T3 ports in the ATM switch, as wellas inexpensive optical-to-electricalconversion performed by fiber optic

modems, which preclude the need foran additional ATM device.

To provide redundancy over the LocalLoop, ACE-101 devices can be locatedat the customer premises and at thecentral office. Fiber optic redundancy isan option which can ensure fulfillingthe network availability stipulated in theservice level agreement (SLA).

A broad range of fiber optic interfaces,including RAD’s unique WDM,1550 nm long-haul and E3/T3 opticalinterfaces, meet customer requirements.

RAD offers a wide range of rate andmedia converters that become themissing link between ATM productswhich have a limited number ofinterfaces and rates. In some cases, theseproducts are also used as repeaters toextend the range of ATM networks.

ATM Service Distribution

To deliver a variety of services – voice,data, ISDN, Frame Relay and IP – itmakes good business sense toconsolidate them both at the customerpremises and the central office. Multipleservices required by a regular customercan usually be packaged in a singleE1/T1 link. Therefore, it is beneficial todeploy standard E1/T1 framing for trafficbundling in the Local Loop whichbecomes advantageous further in thenetwork. This service can be easilyupgraded to accommodate higher

bandwidth using the same infrastructure.RAD’s Multiservice Access Platform(MAP) is based on channelized customer-located access devices, such as FCDintegrating concentrators and Megaplexaccess multiplexers equipped with built-in fiber optic modems.

At the central office, the E1/T1 links areconnected directly to the fiber opticports of RAD’s DXC multiservice accessnode, which performs traffic splittingand/or grooming to different services.

Power companies, railroads, gas companies and other utilitiesthat have their own infrastructure often design applicationsinvolving a central location and a chain of branches.

For TDM drop-and-insert applications, the Kilomux-2100and the Megaplex-2100 transfer voice, data and LAN,dropping part of the traffic at each branch, and passing theremainder on to the next branch.

In a polling environment where there is a host and terminals,the FOM-6MP enables a chain of terminals to be connectedto the host over a single fiber link. RAD provides the physicallayer connectivity, while the polling software mechanism isembedded in the host and terminal equipment.

Fiber

efore the bandwidth explosion that was brought

on by the Internet, the proliferation of intranets,

and other graphics-heavy applications, the use of

fiber optic technology was often stifled by the cost

considerations involved in laying fiber to replace

the existing copper plant. Almost overnight,

exponential increases in demands for

broadband access increased the

feasibility of fiber as an access

medium. This is particularly true

since, compared to fiber, copper-

based DSL technologies do not

meet businesses’ immediate

demands for bandwidth and range.

The natural benefits that are part

and parcel of fiber – data security,

noise immunity and longer range –

make it an ideal long-term investment for

carriers creating

a new infrastructure or for those deploying a

telecommunications infrastructure in a new area.

At the same time that fiber is moving from the backbone

to the Local Loop, it brings with it technology such

as wave division multiplexing (WDM) that increases

the capacity of data transmission over fiber optic

cables all the way to corporate customers in

need of high bandwidth.

RAD Data Communications is a

recognized leader in developing

access equipment that helps bring

fiber optic solutions for the Local

Loop up to the customer premises.

These include multiservice access

nodes, ATM NTUs, multiplexers,

and of course, RAD’s full range

of fiber optic modems.

The following applications, based on projects

already using RAD’s fiber optic products, demonstrate

the versatility and ingenuity of RAD’s fiber optic

access solutions.

RAD’s solutions, which are the basis forthe preceding applications, surpass thecurrent needs of fiber optic networks.They represent a dynamic beginning ofthe possibilities for fiber optic deploymentin the world of telecommunications.

Future developments based on fiber optictechnology are expected to be responsesto the global proliferation of broadbandapplications, such as multimedia residentialservices, telemedicine and distancelearning. Continued growth in worldwidetelecommunications can be expected toencourage a further explosion in the needfor bandwidth and switching speeds.Following Fiber-to-the-Curb (FTTC), Fiber-to-the-Home (FTTH) is the next step inthe universal accessibility of fiber optics.In fact, it is already available in somecountries.

Within the first few years of the newmillennium, we can expect a move towardsPhotonic Superhighways, where opticalsignals will replace electronic signals andthe bandwidth will be much higher thanwhat is currently available, thus eliminatinginformation “traffic jams.“ Backboneswill become more powerful, with accesscapable of delivering high-speed servicesall the way to the customer premises. Andof course, it can be expected that theseimpressive improvements will eventuallyoffer more affordable broadband services.

Sophisticated new services can beexpected to take their place in thetelecommunications marketplace oftomorrow. With a solid track record inthe development of access solutions,RAD Data Communications will remainan industry leader in supporting futurefiber optic technologies.
