RF Signal Management Traditional Splitter/Combiner Installation and Cable Management

Successful signal management in headends of the future will be determined in large part by one issue: the ability to manage the dynamic environment of the return path. New services such as the addition of multiple channel lineups or narrowcast insertion of telephony, PCS, network management or data services, demand two-way signaling and the development of a robust reverse path. At the same time, providing excellent customer service requires a high level of network reliability, often achieved through headend redundancy | RF Signal Management Traditional Splitter Combiner Installation and Cable Management application note Overview Successful signal management in headends of the future will be determined in large part by one issue the ability to manage the dynamic environment of the return path. New services such as the addition of multiple channel lineups or narrowcast insertion of telephony PCS network management or data services demand two-way signaling and the development of a robust reverse path. At the same time providing excellent customer service requires a high level of network reliability often achieved through headend redundancy. To meet these needs the RF distribution and management infrastructure must be flexible reliable and capable of future growth. ADC s traditional splitter combiner product line meets these requirements solves many of the headend signal management problems encountered by design engineers and offers a robust solution that prepares the headend for future requirements. This application note will discuss ADC s traditional splitter combiner and describe its use in basic cabinet and open rack cable management applications. Product Description ADC s traditional splitter combiner products mount in a universal horizontal chassis configuration. As shown in Figure 1 the universal chassis accommodates 2x1 4x1 and 8x1 splitter combiner or directional coupler modules and can be any desired combination. All chassis are 1.75 inches high and mount in 19-inch equipment racks or 23-inch equipment racks with extender brackets ordered separately . Figure 1 Universal Panel Mounting Space Required Per Module Although not shown in Figure 1 a cable tie bar is located at the rear of the chassis. There are 75 Ohm F or BNC connectors mounted on the rear of the modules that when installed into the universal chassis provide the interface for all coaxial connections to the network elements. The universal chassis can support a mixed complement of splitter combiners and directional
