Cisco Series 9900 RF Signal Manager Passive Modules
Advanced HFC networks now include numerous 2-way interactive services that offer
significant new sources of revenue for the system operator. These networks have
changed the requirements for headend/hub RF combining and splitting networks. New
services coupled with fewer homes passed per fiber node require a completely
engineered method of RF signal routing and interconnection at the headends and hubs
where the services originate.

Description
The Cisco
®
Series 9900 RF Signal Manager is a family of products designed to simplify the
complex RF networks that support these key services in HFC system headends and hubs. A
complete family of passive signal splitting and combining modules support both forward (50-1000
MHz) and reverse (5-90 MHz) path applications.

MHz) and reverse (5-90 MHz) path applications.
The Series 9900 RF Signal Manager is a modular system that provides completely symmetrical
splitter/combiner and directional coupler components that mount easily in a multifunction chassis.
Each forward or reverse module is available in 2, 4, and 8-way versions. Directional couplers (10
dB and 20 dB) are also available to provide low loss signal sampling or test point access anywhere
in the network. Each module offers superior electrical specifications compared to taps or generic
headends and hubs where the services splitter/combiner components and is packaged to ensure
outstanding RF integrity. The Series 9900 RF Signal Manager module packaging allows for
maximum product density without exceeding normal practices for accessibility and maintenance.
The 4-way and 8-way versions utilize plug-in attenuator pads for enhanced signal balancing and
matching requirements.
