Disclosed in an embodiment of the present invention are an optical repeater and optical fiber communication system, the implementation solution of the optical repeater comprising: a first input end of the optical repeater, a first output end of the optical repeater, a first erbium doped fiber (EDF), a first coupler, a second coupler and a first pump light processing assembly; the first input end of the optical repeater is connected to the input end of the first EDF; the output end of the first EDF is connected to the input end of the first coupler; the first output end of the first coupler is connected to the first input end of the second coupler; the output end of the second coupler is connected to the first output end of the optical repeater; the input end of the first pump light processing assembly is connected to the second input end of the second coupler; and the output end of the first pump light processing assembly is connected to the second output end of the first coupler. The above solution enables reverse pump light to enter when all pump light of a local terminal becomes invalid, thus improving the reliability of the optical fiber communication system. |
