Abstract

PURPOSE:To achieve sure transmission with a simple timing control, by simplifying a transmission control step. CONSTITUTION:Sensor modules 1A, 1B are of the same constitution, and for example, the module 1A consists of a photodetector 6a receiving an instruction signal in wave length lambda1 given from an optical fiber 2a and converting it into a logical level electric signal, reception amplifier 6b. on-delay type delay circuit 7 delaying the leading of an output (c) of the amplifier 6b for a prescribed time T0, and transmission amplifier 8b and light emitting element 8b receiving an output D of the delay circuit 7 and transmitting the instruction signal in wave length lambda1 to the optical fiber 2b. That is, the module 1A receives the instruction signal from a master station 3, delays it by a time T0 and transmits it to the module 1B at the post stage. Further, a data signal E produced from a data generating circuit 9 is inputted to an OR circuit F, converted into a photo signal in wave length lambda2 with a transmission amplifier 11a and a light emitting element 11b and transmitted to a master station 3.
