METHOD AND APPARATUS FOR CONNECTING AC POWERED SWITCHES, CURRENT SENSORS AND CONTROL DEVICES VIA TWO WAY IR, FIBER OPTIC AND LIGHT GUIDE CABLES
First Claim
1. A method for connecting an AC switching device with an automation controller network device via an optical grid of an optical cable for propagating one way optical signals, said network device comprising a CPU, a communication circuit and an optical transmitter, said AC switching device comprising a CPU, a communication circuit, one of a relay and a switch and an optical receiver for operating an AC load;
- each optical element of said optical receiver and said optical transmitter is enclosed in an opaque socket with an optical access and a holder commensurate with a size and a shape of a terminated end of said optical cable, said method comprising the steps of;
a. terminating one said optical cable at its both ends by a process selected from a group comprising cutting, shaping, polishing, lapping, fitting a plug and combinations thereof for providing a processed surface at both ends of the optical cable;
b. attaching and securing the two processed surfaces of each said terminated end one to each said optical element directly via each said opaque socket by each said holder;
c. introducing to at least one of said CPU an identification pertaining to at least one of said load and said AC switching device;
d. connecting said load to an AC power through said AC switching device; and
e. propagating said one way optical signal including said identification and a control command via said grid for one of switching on and off the AC power feed to said load.

Abstract
A method for connecting an AC powered device, which has an optical receiver, with a control circuit, which has an optical transmitter, using at least on optical medium cable includes the steps of terminating the cable at both of its ends, introducing the processed cable between the receiver and transmitter, attaching and securing one end of the processed cable to the transmitter and the other end of the processed cable to the receiver, and propagating a one way optical signal including control commands from the control circuit to the powered device.
