PURPOSE:To make a high-speed data and picture transmission possible and eliminate power inductive disturbance and interference noise influence by using light as a medium in the communication to a moving object. CONSTITUTION:Optical fiber leakage cable 15 and photo coupler 18 are provided in a ground fixed station and a moving object respectively to constitute a multiplex communication unit, and cable 15 increases the leakage light quantity, and photo coupler 18 couples optical transmitter lambda219 and optical receivers lambda117 and lambda212 on the moving object to the leakage light of cable 15 through a prescribed space distance by a condenser lense, etc. |
