Equipment Description 
 
 
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
