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 superior 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
