Optical submarine cable system that optical repeater of optical submarine cable system and includes an optical repeater

摘要

Communication offers the optical submarine cable system where the possibility all stopping/deciding of being done is low even with when supply of electricity electric current decreases communication by having the optical repeater, and the said optical repeater which the possibility all stopping/deciding of being done are low. Inside the optical repeater plural portion of the light amplifier which is provided and/or, inside the light amplifier plural by the fact that electric power supply to portion of the pump laser which is provided is stopped, the optical submarine cable system which has the optical repeater and the said optical repeater which do not have the times when it is stopped part or all communication is actualized even with when supply of electricity electric current decreases.
