Configuration
There are several versions of this module.
The 1x2 or 1x4 Forward Configuration Module (FCM) is used
when the GS7000 Node is configured with a single optical
receiver routed to all four outputs of the amplifiers. This
module splits the signals equally to the inputs of the RF
amplifier module. (Note that the 1x2 FCM can only be used
with the 2-way RF amplifier module and the 1x4 FCM can only
be used with the 4-way RF amplifier module.)
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 that the 1x2 FCM with forward RF injection can
only be used with the 2-way RF amplifier module and the 1x4
FCM with forward RF injection can only be used with the 4-way
RF amplifier module.)
The 1x2 or 1x4 Redundant Forward Configuration Module is
used when the GS7000 Node is configured with two optical
receivers routed to all four outputs of the amplifiers in a
redundant configuration. Receiver 1 is the primary receiver and
Receiver 2 is the backup. The active receiver is selected with a
status monitor or local control monitor. (Note that the 1x2
Redundant FCM can only be used with the 2-way RF amplifier
module and the 1x4 Redundant FCM can only be used with the
4-way RF amplifier module.)
