Abstract
An optical submarine communication system has a land cable connected to a terminal apparatus which is installed on land near the seashore for transmitting an optical signal and electric power. The land cable is connected to an optical submarine cable through a beach manhole, and a repeater is connected to the optical submarine cable. The optical submarine communication system has a surge suppressor provided on the land cable, whereby a surge generated from the terminal apparatus side because of a lightning stroke or an insulation failure is suppressed from reaching and damaging the repeater.
Claims15
An optical submarine communication system, comprising:
- a land cable connected to a terminal apparatus which is installed on land for transmitting an optical signal and electric power;
- an optical submarine cable including an optical fiber and a feeder line which respectively transmit the optical signal and the electric power from the terminal apparatus;
- a repeater connected to said optical submarine cable, driven with the transmitted electric power and amplifying the optical signal;
- and
- surge suppressing means provided between the terminal apparatus and said repeater, suppressing a surge generated in the terminal apparatus side from reaching said repeater.
