Cable operator networks are large expansive networks that involve hundreds if not thousands of miles of coaxial or fiber cable powered by power supplies in the plant and connecting customers to critical infrastructure facilities such as hubs, headends, data centers, regional and national distribution datacenters. In these facilities is a vast array of equipment responsible for the production and support of the cable products - voice, video and data as well as newer products such as home automation and security, and Wi-Fi to name a few. The importance of powering all of these devices in the critical facilities is ever increasing as the customer expectation of 100% availability of service is growing due to expansion into business services and residential competition from new mark place service providers.
