Abstract: Systems, methods and devices for a coaxial cable transmission system. A power supply receives a primary power signal from a power source. The power supply generates a switched direct current power signal from the primary power signal. A power gateway receives the switched direct current power signal over a coaxial cable from the power supply. The power gateway generates a secondary power signal from the switched direct current power signal. A load device receives the secondary power signal from the power gateway. In some implementations, the power supply generates the switched direct current power signal at a positive direct current voltage level for a first part of a time period and at a negative direct current voltage level for a second part of the time period.

Abstract: An optical cross-connect system and method allows service providers to economically and efficiently handle capacity upgrades to meet future demands. The optical cross-connect can be embodied as a three-stage switch having a first, a middle, and a last stage. Capacity upgrades may be accomplished by adding additional first and last stage switches to meet increased demand and by replacing the middle stage switches. Accordingly, the original first and last stage switches may be retained in the upgraded optical cross-connect. The resulting optical cross-connect may include both optical and electronic components and the upgrade may be performed without interrupting service.
