Model GS7000 4-Port Node 
1 GHz with 55/70 MHz split 
 
The Model GS7000 4-Port Node is our latest generation 1 GHz optical 
node platform and utilizes a completely new housing designed for 
optimal heat dissipation.  This platform allows independent 
segmentation and redundancy for both the forward and reverse paths in 
a reliable, cost-effective package. 
 
 
 
The forward path of the Model GS7000 Node can be deployed with a single 
broadcast 1310/1550 nm optical receiver distributing common services to either 
four output ports (all high level) or six output ports (two high level and four lower 
level).  The forward path can also be segmented by using two independent 
optical receivers that each feed half of the node’s output ports (left/right 
segmentation).  Forward path optical redundancy is supported via the use of 
optional redundant optical receivers.  The type of forward path segmentation 
and/or redundancy is determined by the type of Forward Configuration Module 
installed in the node. 
 
The Model GS7000 Node’s reverse path is equally flexible.  Reverse traffic can be segmented or combined and routed to a 
maximum of 4 FP, DFB, CWDM, or DWDM reverse optical transmitters, or to advanced Baseband Digital Reverse optical 
transmitters as part of the bdr system.  Reverse path optical redundancy is supported via the use of optional redundant optical 
transmitters.  The type of reverse path segmentation and/or redundancy is determined by the type of Reverse Configuration 
Module installed in the node.  A Reverse Input Port is also provided for high frequency (5 – 210 MHz) reverse signal injection. 
 
All optical transmitters and optical receivers used in the GS7000 have new high-profile module covers that include both a self-
contained fiber pigtail storage area and an integrated pull ring for easier module installation and removal.  Additionally, the 
GS7000 optical receiver is a new low-current design that dissipates less power and incorporates a two-state interstage RF 
attenuator switch for performance optimization. 
 
Features 
    Six port 1 GHz RF platform 
   Uses 
GainMaker
 
 type GaAs FET gain stages 
    Uses standard GainMaker style accessories (i.e., attenuator pads, equalizers, diplexers, and crowbar) 
    Field accessible plug-in Forward Interstage Linear Equalizers, Forward / Reverse Configuration Modules, and Signal 
Directors 
    3-state reverse switch (on/off/-6 dB) allows each reverse input to be isolated for noise and ingress troubleshooting (status 
monitoring or local control module required) 
    Auxiliary reverse injection (5 - 210 MHz) configurable on up to 2 ports 
    Positions for up to 4 optical receivers and 4 optical transmitters in housing lid 
    Optional low-cost Local Control Module may be installed in conjunction with a Redundant Forward Configuration Module 
to allow optical path redundancy when no status monitor is required 
    Optional Status Monitoring (ROSA
 
/TNCS or other compatible element management system required) 
    Fiber entry ports on both ends of housing lid 
    Fiber management tray and track provides easy access to fiber connections  
    Primary and redundant Power Supplies with passive load sharing 
    Spring loaded seizure assemblies allow coax connectors to be installed or removed without removing amplifier chassis or 
spring loaded mechanism from the rear of the housing base 
    Dual/Split AC powering
