Course description
The return path in today’s broadband cable network is integral to the successful and reliable operation of cable modems, video-on-demand (VOD), telephony, and other revenue sources. NCTI’s Return Path Operations course introduces the basic concepts of return path functions, and outlines procedures for testing, repairing, and maintaining a viable return path. The course provides details on how ingress, noise, system alignment, optical operations, and installation of equipment at the customer premises can jeopardize return path performance. It then guides the student with instructions on how to mitigate related problems that can occur inside and outside the customer premises, and in the outside network back to the headend over coaxial and fiber-optic cable. Any technician that works in these functional areas of the network will find valuable answers to questions about the return path that they may have been hesitant to ask.
