Cisco GainMaker Optoelectronic Node 1GHz with 65 86 MHz Split Data Sheet

 

 

 
 

The GainMaker

®

 High Output Node is designed to serve as 

an integral part of today’s network architectures, and 
combines the proven technologies of both the GainMaker RF 
Amplifier and Prisma

®

 Optical components.  The GainMaker 

High Output Node is capable of higher output levels than the 
standard GainMaker Node.  Featuring three RF output ports, 
it is the ideal platform for delivering video (digital and analog) 
as well as high-speed data services over advanced hybrid 
fiber/coax (HFC) networks.  With its modular design of fiber 
receiver, reverse fiber transmitter and RF amplifier 
electronics, the GainMaker High Output Node station can 
provide a variety of functions required by advanced networks. 
 
The GainMaker High Output Node accommodates a second 
forward receiver with an RF switch to accommodate forward 
path optical redundancy.  Reverse traffic can be combined 
and routed to FP, DFB, or CWDM reverse transmitters.  The High Gain Dual (HGD) launch amplifier module 
provides two high-level outputs (with the ability to split one internally to feed a third port).  Additionally, the node is 
available with an optional custom status monitoring transponder for use with Scientific-Atlanta’s ROSA

®

 / TNCS 

status monitoring and control element manager.  On-board temperature, automatic gain control (AGC) levels, RF 
switch position, power supply condition, as well as other features/parameters can be monitored through this 
transponder. 
 
 

•  Capable of higher output levels than standard GainMaker Nodes 

•  Forward redundancy with two 1310/1550 nm optical receivers (optional) 

•  Uses plug-in accessories common to all GainMaker products 

•  Cable to Linear EQ in amplifiers I/S EQ spot provides 14.5 dB of Linear tilt 

•  Local test points and LED indicators on optical receivers, transmitters, and optical interface board simplify 

installation and maintenance 

•  AGC has thermal mode, eliminating disruptive RF output variation in the event of pilot loss 

•  QAM Pilot AGC now available in addition to existing analog AGCs 

•  Optional plug-in Status Monitoring 

•  Optional 3-state reverse switch (on/off/-6 dB) allows each reverse input to be isolated for noise and 

ingress troubleshooting (status monitoring required) 

•  Fiber Management tray provides easy access to fiber connections and folds back to provide access to 

optical transmitter and receivers 

•  Reverse input pad and RF test point for each reverse input port on launch amplifier allow optimum reverse 

path design and alignment
