Cisco GainMaker Standard Output Node 1 GHz
with 85/102 MHz Split

Consumer bandwidth demand continues to grow every year. As a result, cable
operators with DOCSIS

-based equipment have begun introducing higher frequency

splits into the network. They want to reduce service group sizes and ultimately double
or quadruple (or more!) bandwidth speeds. The Cisco

GainMaker

85/102 MHz Node

is an ideal product for higher frequency split applications. Why? Because with
increased upstream bandwidth, the upstream data rate needs can be met. The Cisco
GainMaker 85/102 MHz Node continues Cisco’s legacy of providing simple, reliable,
and fast installation and setup. Available with two or three RF output ports, it is an
ideal platform for delivering video (digital and analog) and high-speed data services
over advanced hybrid fiber/coaxial (HFC) networks. With its modular design including
fiber receiver, reverse fiber transmitter, and RF amplifier electronics, the Cisco
GainMaker Node station can provide the full complement of functions required by
advanced networks.

The Cisco GainMaker 85/102 MHz Node (Figure 1) accommodates a second forward receiver with a RF switch for

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 GainMaker High Gain Balanced Triple launch amplifier module provides

three RF outputs. The GainMaker High Gain Dual launch amplifier module provides three RF outputs, with the

ability to split one internally to feed a third port. Additionally, the GainMaker Node is available with an optional

DOCSIS status monitoring transponder.
