Abstract

A polarity switching hybrid interface is configured to couple both optical fibers and electrical conductors. The hybrid interface incorporates polarity switching circuitry such that the polarity of electrical contacts on a first side of the hybrid interface is opposite to the polarity of the electrical contacts on an opposite side of the hybrid interface. As such, the polarity of the electrical conductors coupled to each side of the hybrid interface need not be known. Each side of the hybrid interface is configured to interface with the same type of hybrid optical/electrical connector.
