9. SFP (Small Form-factor Pluggable):

SFP+ (Enhanced SFP)

SFP is a transducer which converts electrical signals to optical signals and vice versa.

SFP transceivers are available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required optical reach over the available optical fiber type (e.g. multi-mode fiber or single-mode fiber). Optical SFP modules are commonly available in several different categories

The SFP is sometimes referred to as a Mini-GBIC.

SFP+ types are used for the connectivity between FSMF system module and FZHA RF module.

The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 10 Gbit/s.

The SFP type 6G SFP+ SX 80M should be used while installing the TDD eNB.

13. RF Jumper installation:

The weather protection kit on the existing antenna connectors has to be removed prior

to the MDT (Activity to be done with the approved TCN no: ) . The RF jumper connection

between the FZHA module and the antenna will be done during the MDT.

All RF jumper cables have to be properly routed without any loop and should be secured

with proper clamps and cable ties.

Super flex jumper cables are used with 7/16 straight male/female connectors & Right

angle male connectors.

The jumpers from the FZHA RFM are connected to the Antenna ports.

The band used for LTE-TDD is ranging from 2582 to 2602 MHz, with a bandwidth of

20MHz.

Each sector will be having 4 jumpers, based on the requirement.

Jumper connectivity: Ant 1 to Ant4 will be used for sec-A, Ant-5 to Ant-8 will be used for

Sec-B from the first RF module and the sec-C will be powered by first 4 ports of the

second RFM.

The existing BPFs will be bypassed physically during the installation.

All jumpers should be routed through the bottom side of the FZHA cover.

None of the cable will be routed through the top part and this prevents the entry of dust

and water, thereby providing IP55 protection.

All connectors should be properly connected and tightened with 25Nm torque.

QN connectors are used at the RFM side. Just push the QN jumper connector to the RFM

port for quick lock. Make sure that you receive a CLICK!!! sound for mating security.

All the jumpers are labeled as per standard & secured with Cable ties

Regardless of the RF module, the ports labelled Ant-1,3,5,7 are connected to -45o port of

the antenna and the ports Ant-2,4,6,8 to the +45o port of the antenna

14. GPS Antenna Installation and Cabling.

TDD LTE uses GPS for synchronisation. The GPS antenna is installed at the cable tray near the Roxtec. The GPS cable is looped near the antenna with a minimum bending circumference of

1m. The extra length of the GPS cable is looped on the cable ladder inside the shelter in

such a way that, it will not disturb for future expansions. The GPS surge arrestor is installed on the wall, above the FCIA cabinet, in between the

two cable trunks. The GPS antenna should be connected to the FSMF directly (without surge arrestor)

while doing the software upgrade. Once the GPS antenna (FYGA) is detected in the site manager, the cable can be cut

accordingly to accommodate the surge arrestor in the GPS cable line.
