Impedance Matching Panel
To keep pace with fast-changing technology and the need for excellent customer service, networks need to be completely flexible yet reliable. To enhance this flexibility, the impedance matching panel allows twisted pair cabling and coaxial cabling to coexist within a bay or bay lineups. A conversion must take place to transfer the signal reliably from one type of media to another. The 75/120 Ohm balun changes the impedance of a transmission line from a 75 Ohm unbalanced coaxial connection to 120 Ohm balanced twisted pair....

CDMA Capacity and Coverage
The performance of a CDMA system can be difficult to assess. Link budget calculations can be used to verify performance margins for a particular set of parameters, but fail to tell the “whole” story in an easy to understand, visual way. In this paper, a graphical depiction of CDMA coverage vs. capacity is shown to be a useful tool in evaluating the performance of a CDMA system. The graphical results are used to show scenarios in which CDMA can be both uplink and downlink limited. In particular, it is shown that in either case, the addition of a low noise tower mounted amplifier (TMA) can benefit both...

Ribbon vs. Loose Tube Fiber Cabling
In the distribution portion of the passive optical network (PON) for fiber-tothe- premise (FTTP) architectures, the choice of fiber cabling – ribbon vs. loose tube – can directly impact ease of installation and future performance. As is usually the case in these networks, specific architectural characteristics and particular applications may dictate the deployment of one type of cable over the other. However, ADC’s experience in developing and manufacturing FTTP network equipment has concluded that in most cases, ribbon cable provides a considerable performance advantage over loose tube in the distribution portion of the PON network....

Dynamic Reconfiguration of Indoor Combination Networks Through the Use of Patch Panels
In terms of flexibility, the traditional combination networks found inside hubs and headends are quite rigid, making it difficult to change combination ratios. Adding radio-frequency patch panels to combination networks adds a high degree of flexibility and allows for different levels of combination without affecting network service.

The Ideal Headend Evolution to Carrier Class
Today’s successful cable operators are ramping up their networks to deliver advanced services—HD video-ondemand (VOD), tiered high-speed data, voice-over-IP (VoIP) and commercial services. MSOs are focused on improving network reliability and customer satisfaction, and understand the importance of “carrier-class” infrastructure. In order to reach the highest level of delivering the extremely reliable services customers expect, MSOs must begin thinking about the “ideal headend.”

Fundamentals of Fiber Cable Management
Lower operations costs, greater reliability and flexibility in service offerings, quicker deployment of new and upgraded services—these are the characteristics of a successful service provider in a competitive global market. Service providers continue to build out high-bandwidth networks around the world. These networks use a great deal of fiber—the medium that meets both their bandwidth and cost requirements. But just deploying the fiber is not enough; a successful fiber network also requires a well built infrastructure based on a strong fiber cable management system. Management of the fiber cables has a direct impact on network reliability, performance, and cost....
