Abstract

A fiber optic connector having a plug portion with first and second ends, the first end receiving a first fiber optic cable(s) providing optical energy and a second fiber optic cable(s) for bi-directional optical data communications. The connector also includes a receptacle portion having first and second ends, the first end for mating with the second end of the plug portion, and the second end having a first pin(s) corresponding to the first fiber optic cable(s), and, a second pin(s) corresponding to the second fiber optic cable, where the receptacle portion further includes a first photodiode(s) corresponding to the first fiber optic cable(s) for converting the received optical energy digital electrical energy for output on the first pin(s), and, a second photodiode(s) corresponding to the second fiber optic cable(s) for converting received optical data communications to digital electrical data communications for output on the second pin(s).
