Reverse Configuration Module
4x2 Reverse Configuration Module with Auxiliary Reverse RF Injection
Description
The 4x2 Reverse Configuration Module with auxiliary reverse RF injection combines
reverse inputs from Ports 1 and 2/3 and routes them to Transmitter 1; it also
combines reverse inputs from Ports 4 and 5/6 and routes them to Transmitter 3. An
RF signal from an external source can optionally be injected and coupled with
reverse RF inputs from Ports 3/6 and routed to Transmitter 1.
Note: This module can only be used with an 8-port optical interface board. (There is
no transmitter 3 position with a 6-port optical interface board.)
The following diagram shows how this module functions.
