following step
s to route and connect the simplex path coaxial cables to the Host Unit:
1. Obtain the required lengths of high performance, flexible, low loss 50Ω coaxial communication
cable for all coaxial connections.
2. Route the RF Tx and Rx path coaxial cables between the Host Unit and BTS interface and cut to
the required length.
3. Terminate the cable with a QMA male connector.
4. Connect the Tx and Rx cables from the BTS to the Tx and Rx connectors on the BIU front panel
corresponding to the frequency band (e.g. Tx 700, Tx 850, Tx1900, Tx 2100 or Tx2600).

5. Dress and secure cable at the Host Unit.
6. The RF inter-connection between the BIU and the FIU uses QMA to QMA jumper cables supplied
with the mBSC-C equipment.
4.3.2.3 Optical Connections
The optical interface between the Host Unit and the Remote Node is supported by an E2000/APC optical
adapter which is mounted on the FIU front panel. A single mode, E2000/APC patch cord may be used to
connect the Host Unit with Remote Node.
Use the following steps to connect the optical fibers:
1. Obtain one patch cord which is sufficient length to reach from Host Unit to the Remote Node.
2. Clean each patch cord connector following the patch cord supplier’s recommendation.
3. Push and secure the patch cord connector into the desired optical port on the Host Unit FIU
