PURPOSE:To synchronously transfer in supermulti parallels and to provide the wiring of high speed and high density making the most use of the light weight and the fine wires of fibers by using the parallel light transmitting device whose propagation delay time from inputting electric signal to outputting electric signal is set within a certain fixed range. CONSTITUTION:The absolute time of signal propagation period of time at every array is controlled in order to insure the simultaneous arrival of the signals among the arrays. By arranging a lot of these controlled transmission modules 1j and reception modules 3j side by side, paralleling degrees are made larger with no adjustment. In order to realize it, the respective signal propagation period of time from the electrical input of a transmission part (or the module 1j) to a light ray output reference plane (an optical connector contact surface) and from the light ray input reference plane (an optical connector contact surface) of a reception part (the modules 3j) to the output of the electric signal, and the respective light propagation period of time of the optical wave guide bundles 20i and 20j of fiber arrays or the like is beforehand set within the ranges specified respectively. Thus, the standardization of the respective parts is enabled. |
