GS7000 4-Way Segmentable Node scales to meet growing usage with the
built-in flexibility to segment forward and reverse paths independently as requirements

– all 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 non-
segmented mode with a single broadcast optical receiver distributing common RF services either to four output
ports (all high level) or to 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 feed their own output ports, or it can be left/right
segmented by u
sing two independent optical receivers that each feed 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 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 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 has two optical receiver designs. One is optimized for standard
optical input levels and the other is optimized for low optical input levels. Both incorporate a two-state interstage RF
attenuator switch for performance optimization.
