Installing the network cables

Figure 18. Fiber-optic SC cable connectors

Do the following to connect the dual singlemode fiber-optic cable (see 

) to the STM-1 SC connectors:

1. Remove the protective cap from the fiber optic cable connectors.

2. Attach the transmit fiber-optic cable connector to the TX SC connector on the rear blade (see 

page 35). 

3. Attach the receive fiber-optic cable connector to the RX SC connector on the rear blade. 

Connecting the STM-1 electrical interface to coaxial network cables
The Matrix Switch presents the STM-1 electrical interface on a pair of 75-ohm female BNC connectors, one 
for the transmiting (TX) and one for receiving (RX) signals (see 

 on page 35). 

For most installations, the coaxial cable connecting the STM-1 WAN port to the SDH network can be no 
longer than 325 feet (100 meters).

The Matrix Switch electrical interface transmits a STM-1 signal with 
an attenuation margin of 12.7dB at 78 MHz over coaxial cable. The 
12.7dB attenuation margin typically results in a transmission distance 
limitation of approximately 360 feet (110 meters) for RG-59U 
coaxial cable.
