broadcast 1310/1550 nm optical receiver with common services distributed to four
output ports (all high level). The forward path is configured by using either one
optical receiver or one remote PHY module that feeds all output ports.
Reverse traffic can be segmented or combined and routed to up to two DFB reverse
optical transmitters, or up to two Enhanced Digital Return reverse optical
transmitters as part of our EDR system. Reverse segmentation is configured by
setting the reverse segmentation switch to the appropriate setting.
The 1.2 GHz SHO 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 42/54 MHz,
and 85/102 MHz.
The 1.2 GHz SHO GS7000 Node utilizes the transmitter and receiver module covers
that have been designed to allow fiber pigtails storage within them, providing
improved fiber management within the node.
Up to one optical receiver, up to two analog or two digital transmitters, and one
Remote-PHY device can be installed in the 1.2 GHz SHO GS7000 Node.
45 - 90 V AC input power is converted to +24.5, +8.5, -6.0, and +5.5 V DC by an
internal power supply to power the 1.2 GHz SHO GS7000 Node.
Features
The 1.2 GHz SHO GS7000 Node has the following features:

Four port 1.2 GHz RF platform

Uses GaN Technology on the interstage and output stages

Uses standard GainMaker style accessories (i.e., attenuator pads, equalizers,
diplexers and crowbar)

Field accessible plug-in Forward Linear Equalizers

3-state reverse switch (on/off/-6 dB) allows reverse input to be isolated for
noise and ingress troubleshooting (status monitor or local control module
required)

Fiber entry ports on both ends of housing lid

Fiber management tray and track provides easy access to fiber connections

Primary and redundant power supplies with passive load sharing

Spring loaded seizure assemblies allow coax connectors to be installed or
removed without removing amplifier chassis or spring loaded mechanism
from the rear of the housing base

Dual/Split AC powering
