Forward Configuration Module
Introduction
The forward configuration module determines the forward path topology in the RF
amplifier module and the GS7000 Node. The output signals from one to four optical
receivers enter the forward configuration module where they are combined or
directed to the two independent forward paths in the RF amplifier module. The
various versions of the forward configuration module are described below.

1x2 and 1x4 Forward Configuration Modules Description
The 1x2 or 1x4 Forward Configuration Module is used when the GS7000 Node is
configured with a single optical receiver routed to all four outputs of the RF
amplifier module. This module splits the signals equally to the inputs of the RF
amplifier module.
Note: The 1x2 FCM can only be used with the 2-way RF amplifier module. The 1x4
FCM can only be used with the 4-way RF amplifier module.
The following diagram shows how this module functions.

1x2 and 1x4 Forward Configuration Modules with Forward RF Injection
Description
Description
The 1x2 and 1x4 Forward Configuration Modules with forward RF injection are
similar to the 1x2 and 1x4 Forward Configuration Modules, but are used with the
Forward Local Injection (FLI) Module. The FLI Module routes an RF signal from an
external source to the Forward Configuration Module which is then coupled with
other inputs from an optical receiver.
Note: The 1x2 FCM with forward RF injection can only be used with the 2-way RF
amplifier module. The 1x4 FCM with forward RF injection can only be used with the
4-way RF amplifier module.
