FIBER PUMP LASER SYSTEM AND METHOD FOR SUBMARINE OPTICAL REPEATER

Last updated:

Abstract:

An optical communication system is disclosed. The optical communication system may include a first fiber pump laser system having a first single mode (SM) fiber output configured to output a first pump laser radiation, a second fiber pump laser system having a second SM fiber output configured to output a second pump laser radiation, at least one combiner-splitter element configured to combine the first pump laser radiation and the second pump laser radiation and to transmit N portions of pump laser radiation, and N doped fiber amplifiers, where N is at least four, each doped fiber amplifier configured to receive one portion of the N portions of pump laser radiation and an input optical signal to be amplified, amplify the input optical signal into an amplified optical signal, and to transmit the amplified optical signal.
