Introduction
This chapter describes the theory of operation for the GS7000
GainMaker Scalable 4-Port Node, including functional descriptions of
each module in the node.
The GS7000 Node is comprised of two parts, the lid and the base.
The lid houses an optical interface board (OIB), one to four optical
receivers, one to four optical transmitters, one digital return module
with one or two digital transmitters, EDFA (optional), optical switch
(optional), a status monitor (optional ) or a local control module
(optional), one or two power supplies, and a fiber management
tray/track.
The base houses the RF amplifier module and the accessories that plug
into it. These accessories include a forward configuration module, two
or four forward band linear equalizer modules, multiple attenuator
pads, two node signal director jumper or splitter modules, and two
auxiliary reverse injection director modules. Also contained within the
launch amplifier module are a reverse auxiliary
jumper/amplifier/termination module and a reverse configuration
module.
