Description

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 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/parameters can be monitored through this transponder.
Features

• Capable of higher output levels than standard GainMaker Nodes

• Forward redundancy available via 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 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

Notes for Optical Section Specifications:
1. For forward receiver module only. Does not include frequency response contributions from forward optical transmitter.
2. Minimum receiver RF output level for the stated transmitter percent OMI/ch. (Optical Modulation Index per channel), with receiver optical input power of 0 dBm. To determine RF output levels at other optical input power, add (or subtract) 2 dB in RF level for each 1 dB increase (or decrease) in receiver optical input power.
For reverse optical transmitter and link performance, see the "Analog Reverse Optical Transmitters with Thermal Compensation" data sheet.

Notes for RF Section Specifications:
1. Reference output tilt and internal tilt are both "Linear" tilt.
2. Forward Gain and Noise Figure measured with 0 dB input EQ and 1 dB input pad.
3. Forward internal tilt specified is primarily due to an on-board equalizer and a factory configured 10.5 dB cable to linear interstage equalizer (ISEQ).
4. The forward reference output tilt specified is achieved via field installation of appropriate input EQ, in conjunction with the internal tilt of the launch amplifier and the tilt associated with the optical link (transmitter/receiver combination).
5. Station performance can be determined by combining optic performance and launch amplifier performance. Stated distortion performance is for launch amplifier section operated at reference output levels and tilt. Consult Cisco System Engineering for CIN calculations.
6. Reverse output reference level at the RF output of the launch amplifier.
7. Reverse Operational Gain, Noise Figure, and Return Loss are specified without reverse switch option. If switch is installed, reduce Gain by 0.5 dB, increase Noise Figure by 0.5 dB, and decrease Return Loss by 1 dB.
8. Station reverse gain from station input(s) to reverse transmitter input. With 0 dB reverse input pad, 1 dB reverse output pad, and 0 dB reverse EQ in launch amplifier. Includes optical interface board losses.
9. "Digital" refers to 550 - 1002 MHz loading with QAM carriers at -6 dB relative to analog video carrier levels.
10. Composite Intermodulation Noise is a broadband noise-like distortion product associated with QAM loading.
11. Insertion loss from optical receiver RF output to launch amplifier RF input, with specified forward plug-in module installed in the optical interface board. Subtract this loss from the launch amplifier operational gain to determine forward station gain from optical receiver output to station output.
12. Reverse Gain and Noise Figure for launch amp with 0 dB reverse input pad, 0 dB reverse output EQ, and 1 dB output pad.
13. X-mod (@ 15.75 kHz) specified using 100% synchronous modulation and frequency selective measurement device.

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.
