摘要：
At least one optical repeater is connected in series to an optical signal transmission fiber of an optical fiber cable interconnecting transmitting and receiving terminals, and the optical repeater has an optical amplifier which is excited by pump light to amplify signal light. The pump light is supplied from the outside of the optical repeater, and the pump light supplied is input into the optical amplifier via at least one of its input end and output end. The optical repeater may include an optical divider for dividing the pump light supplied thereto into two, which are input into the optical amplifier via its input end and output end, respectively.
