OPTICAL SUBMARINE CABLE REPEATER

摘要

PURPOSE:To ensure assured and effective repair for an optical submarine system, by providing a coupling part which is detachable to a repeater box with a watertight structure and connecting the electric signals via this coupling part between a transmission line and a feed line. CONSTITUTION:A repeater box 4 can be divided at the part shown by arrows 9, and the transmission of information and the connection of electric power in the inside of a repeater can be performed by respective connectors 16 and 18. The divided repeater boxes 3 and 5 are connected together mechanically to ensure the transmission of the tension of an optical submarine cable 2 that is applied to the box 4 and to secure an watertight structure in the box 4. The optical signal transmitted through an optical fiber 6 is converted into an electric signal through a photoelectric converter 10 and then amplified by electric signal amplification processor 11 and 13. This amplified signal is converted again into an optical signal through an electrooptic converter 14 to be transmitted through an optical fiber 7. At the same time, the electric power is fed via an electric power feed line 8.
