| titleOfInvention | Optical repeater and method of relaying optical signal |
| abstract | An object is to respectively provide excitations light from a plurality of light sources to an odd number of fiber pairs. Optical amplifiers (A1 to A6), an optical multiplexer/demultiplexer (C11) are disposed in three fiber pairs including two optical fibers through which optical signals are transmitted, respectively. The optical multiplexer/demultiplexer (C11) has inputs connected to light sources (LS1, LS3, LS5) and three outputs. An opticalmultiplexer/demultiplexer (C12) has inputs connected to light sources (LS2, LS4, LS6) and three outputs. In opticalmultiplexers/demultiplexers (C21 to C23), one input is alternatively connected to any one of the three outputs of the optical multiplexer/demultiplexer (C12), the other input is alternatively connected to any one of the three outputs of the optical multiplexer/demultiplexer (C12), one output is alternatively connected to one optical fiber of any one of the three pairs, and the other output is alternatively connected to the other optical fiber of any one of the three pairs. |
