Abstract

PURPOSE:To secure the perfect non-induction and nonmetalization by supplying the light via the optical fiber in the form of the feeding system of the optical repeater. CONSTITUTION:Light transmission end office 1 includes optical signal transmitters 4a-4n, and the electric signal is converted into the optical signal. The optical signal is then sent to light repeating center 2 via signal fibers 5a-5n to be given one the photoelectric conversion through optical repeaters 6a-6n and then converted again into the optical signal after amplifying process and others to be transmitted to repeating center 3 through signal fibers 7a-7n. At the same time, feeding light source 8 is provided at office 1, and thus the light is transmitted to centers 2 and 3 through feeding fiber 9. And part or the whole of the transmitted light is taken into the repeating center via optical coupler 10 and then converted into the electricity via photoelectric converter 11 to be used as the power source for repeaters 6a-6n and others. Thus the perfect non-induction and nonmetalization can be realized for the light supply system.
