22 January 1982 Control And Monitor System Using Fiber Optics In A Blast And Thermal Environment

A control and monitor system has been developed for a nuclear Thermal Radiation Simulator (TRS) which uses a unique fiber optic data link. The system will operate up to nine TRS arrays that are positioned at various remote locations. Each array is operated by a local microprocessor that performs control and monitor functions. Master system control and monitor functions are performed by a central minicomputer. Communications between the local microprocessors and the central minicomputer are performed via three 2200-meter fiber optic data links. Each data link will operate up to three TRS arrays. A newly developed optical coupler supports simultaneous duplex data transmission on a single fiber. The fiber data link operates at 150 kilobits per second, with the capability of operating in excess of 2 megabits per second, at a bit error rate of < 10-9. The system uses low cost step index fiber, LED transmitters and PIN diode receivers in addition to the optical couplers. The coupler boasts parameters of < 2 dB receive input loss, < 1.5 dB transmitter output loss, and transmitter-to-receiver isolation of 40 dB when operated at 820 nanometers.
