four separate and independent forward amplification paths, each
having one or two RF outputs.
four independent reverse inputs.
forward and reverse bandwidths that are established by diplexer
and reverse amplifier assembly selection.
The 1x4 Forward Configuration Module (FCM) is used when the 1.2
GHz 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. The 1x4 Forward
Configuration Modules with forward RF injection are similar to the
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.
The 1x4 Redundant Forward Configuration Module is used when the
1.2 GHz 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.
