OL-29643-02
The optical switch module is used for switching the input of an EDFA module from
a primary signal to a backup or secondary signal. The switch is monitored and
controlled by the Status Monitor/Local Control Module (SM/LCM) in the node.
A specific model of the SM/LCM is required for use in the hub node. This SM/LCM
model monitors and controls several EDFA and optical switch parameters and
functions while continuing to monitor the standard node components.

Features
The GS7000 Node has the following features:
Six port 1 GHz RF platform
Uses proven GainMaker type GaAs and GaN FET gain stages
Uses standard GainMaker style accessories (i.e., attenuator pads, equalizers,
diplexers and crowbar)
diplexers and crowbar)
Field accessible plug-in Forward Interstage Linear Equalizers,
Forward/Reverse Configuration Modules, and Node Signal Directors
Forward/Reverse Configuration Modules, and Node Signal Directors
3-state reverse switch (on/off/-6 dB) allows each reverse input to be isolated
for noise and ingress troubleshooting (status monitor or local control module
required)
