Presentation transcript:

Innovation in CATV powering design In the early stages of the CATV industry trunk & drop coaxial cables & power amplifiers were used to reach the end user. Due to a high demand on network usage the fiber optic applications are extended closest to the customers’ premises leaving most of the existing coaxial cables unused. Safecom is now offering advance technology to reuse those existing coaxial cables as a power & two way backup platform to all optical nodes at FTTN, FTTC , FTTB & FFTH networks. This new system offers the most reliable powering solution while saving enormous Capital & Operational costs for individual powering feeds & maintenance costs for batteries .
