Looking for the ideal platform for delivering digital and analog video and high-speed data services over advanced hybrid fiber/coax (HFC) networks? Look no further. The GainMaker® High Output Node is designed to serve as an integral part of today's network architectures. It 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 standard Cisco® GainMaker Nodes. 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 provide forward path optical redundancy. Reverse traffic can be combined and routed to distributed feedback (DFB), coarse wavelength-division multiplexing (CWDM), dense wavelength-division multiplexing (DWDM), or Enhanced Digital Reverse (EDR) transmitters. The High Gain Balanced Triple (HGBT) launch amplifier module provides three high-level outputs. Additionally, the node is available with an optional DOCSIS status monitoring transponder. On-board temperature, automatic gain control (AGC) levels, RF switch position, power supply condition, as well as other features and parameters can be monitored through this transponder.
Features
● Capable of higher output levels than standard GainMaker nodes
● Forward redundancy available through a second 1310/1550 nm optical receiver (optional)
● Uses plug-in accessories common to all GainMaker products
● Cable to linear EQ in amplifiers I/S EQ spot provides 15.5 dB of internal 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
● Optional plug-in for 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

Data is based on stations configured for 2-way operation with status monitoring transponder. AC currents specified are based on measurements made with typical CATV type ferro-resonant AC power supply (quasi-square wave), and GainMaker High Output Node DC power supply (3.4 amp, 24 V DC, pn 4022705).
DC supply has a user configurable 40 V or 50 V AC under-voltage lockout circuit.
Note: 1. The total DC Power consumption of installed components should not exceed the power supply DC current rating.
