The Cisco® GS7000 High-Output Segmentable Node with 42/54 MHz Split is the latest-generation 1-GHz optical node platform designed to support fiber deep applications of up to 60 dBmV. This platform allows independent segmentation and redundancy for both the forward and reverse paths in a reliable, easily configurable, technician-friendly package.

The forward path of the Cisco GS7000 4-Way Segmentable Node launch amplifier can be initially deployed in nonsegmented mode with a single broadcast optical receiver distributing common RF 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 fully segmented by using four independent optical receivers that each feeds its own output port, or left/right segmented by using two independent optical receivers that each feeds half of the node's output ports. Forward path optical redundancy is also supported using optional redundant optical receivers. The type of forward path segmentation and/or redundancy is determined by the type of Cisco GS7000 Forward Configuration Module installed.

The Cisco GS7000 Node's reverse path is equally flexible. Reverse traffic can be segmented or combined and routed to a maximum of four Fabry-Perot (FP), distributed feedback (DFB), coarse wavelength-division multiplexing (CWDM), or dense wavelength-division multiplexing (DWDM) reverse optical transmitters, or to the Cisco GS7000 Enhanced Digital Reverse (EDR) optical transmitters as part of the EDR system. Reverse path optical redundancy is supported using optional redundant optical transmitters. The type of reverse path segmentation and/or redundancy is determined by the type of Cisco GS7000 Reverse Configuration Module installed. 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 Cisco GS7000 platform 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 has a new low-current design that dissipates less power, and incorporates a two-state interstage RF attenuator switch for performance optimization.All optical transmitters and optical receivers used in the Cisco GS7000 platform 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.
