Abstract

A composite cable breakout assembly is disclosed. The assembly includes an enclosure for receiving a composite cable having a fiber optic cable with at least one optical fiber and an electrical power cable with at least one electrical conductor. The enclosure has at least one port providing passage to the exterior of the enclosure. The at least one optical fiber is terminated by a fiber optic connector and the at least one electrical conductor is terminated by an electrical connector. Alternatively, the at least one optical fiber and the at least one electrical conductor may be terminated by a composite optical/electrical connector. The fiber optic cable and the electrical power cable route to the at least one port enabling connection external to the enclosure for extension of optical signal and electrical power to components external to the enclosure.

Claims
