1. A piece of cable television (CATV) equipment having a specialized Uninterruptible Power Supply (UPS), comprising:
the piece of CATV equipment, having an outer housing providing a hermetically sealed environment to the interior of the piece of CATV equipment and being deployed outdoors in-between a cable headend and a customer premises, comprising:
a coaxial cable power input;
a main power supply designed to supply an entirety of the piece of CATV equipment with a particular amount of power continuously while there is AC power supplied to the piece of CATV equipment over the coaxial cable power input; and
an internal Uninterruptible Power Supply (UPS) for supplying power to either the entirety of the piece of CATV equipment or a proper subset of subcomponents within the piece of CATV equipment when the piece of CATV equipment is not supplied AC power over the coaxial cable power input, wherein the energy storage element of the internal UPS is capable of supplying power for a duration no longer than about an hour and consists of one or more capacitors and does not include a battery,
wherein the internal UPS adjustably reduces how much power is supplied to certain subcomponents, not in said proper subset of subcomponents, of the piece of CATV equipment while maintaining to supply said proper subset of subcomponents with said particular amount of power to conserve an amount of power remaining in said energy storage element.
