Digitized Return Path: Extending the Applicability of Hybrid-Fiber Coax Architectures for Full-Service Networks (1999)

By Farr Farhan, Scientific-Atlanta, Inc.

In this paper, the concept of digitizing the Hybrid Fiber Coax Reverse (or Upstream) path is introduced. The Pros and Cons of such a concept are compared against the existing and traditional methods. The cost, performance and evolution potential of this concept are presented, as well as preliminary lab trial data. Some of the concepts are explored further noting some implementation challenges. In closing, some other evolutionary possibilities for the CATV Hybrid-Fiber Coax architectures are discussed.
