Appendix A Install Your Fiber Repeater Modules and Repeater Adapters
Connect Fiber Repeater
Modules This section describes how to connect cables for fiber repeater modules (other
than the 1786-RPFS; see
page 65 ). A tracer on a duplex cable helps to identify
and follow the cable throughout your system. A tracer is one of the two wires on
the duplex cable that is one of the following:
• Printed with the cable legend
• Ribbed
Connect the cable between the fiber modules by making a simple crisscross
connection. To do this, you will connect the cables between modules from the
receive (RX) end of one channel to the transmit (TX) end of the other module,
as shown in the following diagram.
Do these steps to connect the cable.
1. Use the tracers on the cable to identify which cable is connected to the
receive (RX) port and which one to the transmit port (TX).
2. Connect the receive port (RX) and transmit port (TX) at the
starting module.
3. Do the following to attach the cable connector to the module connector.
a. Align the key of the cable connector with the slot in the module
connector, and insert the connector into the RX port.
b. Push and twist the locking cap until the bayonet lug is locked into place.
TIP Channels 1 and 2 on the module are identical. Channel 1 of a module can
be connected to either channel of another module.
