Abstract

PURPOSE:To omit the timing extracting circuit as well as to eliminate the data-type limitation by transmitting both the data signal and the clock signal by the light of different wavelengths and via piece of the optical fiber. CONSTITUTION:Both the data signal and the clock signal of master station 1 are converted to the optical signals of different wavelengths through conversion multiple isolator 2 to be then transmitted to optical fiber 5. Each signal in fiber 5 is supplied to conversion multiple isolators 4-1, 4-2 and 4-n which are connected into a loop, where the clock signal and the data signal undergo the wavelenght isolation to be converted into the electric signal. And the data signal is transferred between slave stations 3-1-3-n, and the clock signal is branched off to be supplied to each slave station. At the same time, the data signal sent from the slave station is converted into the optical signal to be then transmitted to fiber 5.
