ABSTRACT:
An optical data transmitting technique duplicates optical paths and includes: a divider for dividing electrical data transmitted to an optical data transmitting device of a counterpart device, into first and second output paths; a first optical data transceiver for converting first output path electrical data into optical data and transmitting it to a first receiver of the optical data transmitting device of the counterpart device, outputting first alarm data indicative of an abnormal existence or a nonexistence of the operation upon transmitting the data to the first receiver, receiving and converting optical data transmitted from a first transmitter of the optical data transmitting device of the counterpart device into electrical data, and supplying it to a first input path; a second optical data transceiver for receiving and converting optical data transmitted from a second transmitter of the optical data transmitting device of the counterpart device into electrical data, and supplying to a second input path, converting second output path electrical data into optical data, and transmitting it to a second receiver of the optical data transmitting device of the counterpart device, and outputting second alarm data indicative of an abnormal existence or a nonexistence of the operation upon transmitting the data to the second receiver; and a selector for selecting first input path electrical data in response to the normal state of the first alarm data and selecting second input path electrical data in response to the normal state of the second alarm data.
