Abstract
Abstract An active cable that is configured to communicate over much of its length using one or more optical fibers, and that includes an integrated electrical connector at at least one end. The active cable includes an integrated eye safety controls to thereby reduce the chance of injury should the active cable be severed, or otherwise unplugged at an optical end, if any. The cable may be an electrical to optical cable, and electrical to electrical cable, or one of many other potential configurations.
