Cisco Model GS7000 4-Port Node 1 GHz with 42 54 Split Installation Guide
Model GS7000 Node Description
4015678 Rev B
5
The Model GS7000 Node receives forward optical inputs, converts the input to an
electrical radio frequency (RF) signal, and outputs the RF signals at up to six ports.
The forward bandwidth is from 52 MHz (or 54, or 70, or 86 MHz) to 1002 MHz. The
lower edge of the passband is determined by the diplex filter and the reverse
amplifier assembly. Diplex filter choices are 52 MHz, 54 MHz, 70 MHz, or 86 MHz.

The forward path of the Model GS7000 Node can be deployed with a broadcast
1310/1550 nm optical receiver with common services distributed 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 one optical receiver that feeds all
output ports, two independent optical receivers that each feed half of the node’s
output ports (left/right segmentation) or four independent optical receivers that
feed four independent forward paths. Forward optical path redundancy is
supported via the use of optional local control module. The type of forward
segmentation and/or redundancy is determined by the type of RF amplifier
assembly and 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 up to four FP or DFB reverse optical
transmitters, or to two advanced Baseband Digital Reverse optical transmitters as
part of our bdr

The Model GS7000 Node accepts Optical Transmitter Modules based on the existing
694x/GainMaker optical transmitters. Reverse optical transmitters can be installed
to transmit data, video, or both. Reverse bandwidth is determined by the diplex
filter and the reverse amplifier assembly. Diplex filter choices are 40 MHz, 42 MHz,
55 MHz, or 65 MHz.

A new Low Power Receiver has been developed for the Model GS7000 Node, and is
compatible with existing 694X and GainMaker Nodes. The Model GS7000 Node
utilizes new transmitter and receiver module covers that have been designed to
allow fiber pigtails storage within them, providing improved fiber management
within the node.
