Model GS7000 Optical Hub

As operators migrate to architectures with deeper fiber reach, there is an increased need

for flexible design options and efficient fiber utilization in the optical network. The Model

GS7000 Optical Hub addresses those needs by providing multiple options for optical

amplification, filtering, splitting, and combining, all in a field-proven Model GS7000

station.

The Model GS7000 Optical Hub employs a modular approach, allowing full configuration flexibility

combined with simple component installation and removal. The Model GS7000 active optical

modules include a variety of low-noise EDFA optical amplifiers for both broadcast and narrowcast

applications, as well as optical switches that enable redundancy.

The Model GS7000 passive optical modules include single-function modules such as CWDM and

DWDM 1x8 mux/demux’s, two and four band mux/demux’s, and a variety of optical splitters. Multi-

function passive modules are also available, including combiners with integrated multiplexers and

demultiplexers for narrowcast/broadcast overlays. The passive optical modules with higher

input/output fiber counts make use of a multi-fiber ribbon cable which simplifies internal fiber routing

and connectivity.

A fully configured Model GS7000 Optical Hub can combine narrowcast/ broadcast using up to 64

wavelengths, providing forward and reverse optical paths for a total of 32 nodes. The station

utilizes the same field-proven housing and dual internal power supplies as the widely deployed

Model GS7000 4-Port Node.
