A Cost and Performance Comparison Between Uncompressed Digital Video and Lightly Loaded AM Supertrunking Methods within CATV Network Upgrades and Rebuilds (1994)
By Robert W. Harris, C-COR Electronics, Inc.
This paper compares two types of fiber optic supertrunking methods - Lightly Loaded AM (LIAM) and uncompressed digital video - to determine the "overall" cost and performance impact on 750 MHz CA1V upgrades and rebuilds employing a supertrunk. The analysis outlines channel loading, performance, fiber requirements, cost, and system compatibility issues for both AM and Digital supertrunking technologies. Included is a discussion of the advantages and disadvantages of each method as well as the associated cost and performance tradeoffs. It is found that the choice of supertrunking technology has a notable impact on the end-of-line system performance and, hence, the total cost of the CA1V network upgrade or rebuild.
