GS7000 4-Port Node 1GHz
The Model GS7000 4-Port Node is Scientific-Atlanta’s 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, or CWDM reverse optical transmitters, or to advanced Baseband Digital Reverse optical transmitters as part of Scientific-Atlanta’s 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.
