バ伝送データ多重伝送装置。 A multiplex transmission device that uses optical fiber as a transmission path to time-division multiplex transmit multiple contact signals or binary signals obtained by quantizing analog signals. A self-station address setting means for setting an address, a timer circuit for transmitting own-station data at a predetermined cycle, and an address included in the received data after converting the received serial signal into a parallel signal, and the own-station address setting means for setting an address. It compares with the set address to determine whether it matches or does not match, and if they match, it is stored in the output register and output to the outside, and if it does not match, it is stored in the data relay register and a time notification signal is issued from the time limit circuit. The output of the data relay register whose priority is determined based on the data regeneration relay request signal or the parallel data of the own station data and a signal in which an error detection code and a delimiter code are added to the address are converted into a serial signal. 1. An optical fiber transmission data multiplex transmission device, characterized in that it has a configuration in which signal input/output devices equipped with control means for performing optical conversion to generate optical signals and transmitting the generated optical signals downstream are connected in a cascade or ring configuration.
