Cisco GainMaker Reverse Segmentable Node - 1GHz with 40 52 MHz Split Network Equipment Data Sheet

Optoelectronics
GainMaker® Optoelectronic Node 1 GHz with 42/54 MHz Split
Description
The GainMaker® Node is designed to serve as the
cornerstone of today’s emerging fiber deeper network
architectures. The GainMaker Node combines the superior
proven technologies of both the GainMaker RF Amplifier and
Prisma® Optical components. Available with two or three high
level 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 Node station can
provide the full complement of functions required by advanced
networks.
The GainMaker 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 launch amplifier module provides two high-level outputs (with the ability to split one internally to feed a
third port). Additionally, the GainMaker 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.
Installation of the GainMaker Node is quick and easy. The GainMaker Node can be ordered as a complete node
or as an upgrade kit for existing GainMaker System amplifiers. The fiber receiver is delivered with
preconnectorized fiber terminations. The optional preconnectorized cable stub is the ideal method for connecting
the GainMaker Node to the fiber network (see cable stubs data sheet). External termination connectors are also
available for central strength member and LXE style fiber optic cables. The GainMaker Node includes a 4-fiber
handling tray for these cables.
System reliability and upgrade flexibility are integral to the construction of the GainMaker Node. Key features
include a chromate plated housing to withstand harsher operating environments, local status monitoring of each
module, and a 1 GHz housing for future higher bandwidth applications.

Forward redundancy with two 1310/1550 nm optical receivers (optional)
Fiber management tray provides fiber and connector storage for up to 4 connector pairs
Local test points and LED indicators on optical receivers, transmitters, and optical interface board simplify
installation and maintenance
Optional 3-state reverse switch (on/off/-6 dB) allows each reverse input to be isolated for noise and
ingress troubleshooting (status monitoring required)
The GainMaker node uses plug-in accessories common to all GainMaker products
AGC has thermal mode, eliminating disruptive RF output variation in the event of pilot loss
Reverse input pad and RF test point for each reverse input port on GainMaker launch amplifier allow
optimum reverse path design and alignment

Reference output tilt and internal tilt are both “Linear” tilt.
Forward Gain and Noise Figure measured with 0 dB input EQ and 1 dB input pad.
Forward internal tilt specified is primarily due to an on-board equalizer and a factory configured 7.5 dB linear interstage equalizer
(ISEQ).
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).
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.
Reverse output reference level at the RF output of the launch amplifier.
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.
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.
“Digital” refers to 550 - 1002 MHz loading with QAM carriers at -6 dB relative to analog video carrier levels.
“Digital” refers to 650 - 1002 MHz loading with QAM carriers at -6 dB relative to analog video carrier levels.
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.
Reverse Gain and Noise Figure for launch amp with 0 dB reverse input pad, 0 dB reverse output EQ, and 1 dB output pad.
X-mod (@ 15.75 kHz) specified using 100% synchronous modulation and frequency selective measurement device.
Unless otherwise noted, specifications reflect typical performance and are referenced to 68°F (20°C). Specifications are based
upon measurements made in accordance with SCTE/ANSI standards (where applicable), using standard frequency assignments.
