Abstract

The invention provides an underwater optical signal amplification relay with a demodulation function, and a submarine monitoring system. The underwater optical signal amplification relay comprises a pressure bearing cylinder, end covers, a photoelectric separation module and a photoelectric processing module; wherein the photoelectric processing module is used for performing amplification transmission on a downlink analog optical signal transmitted in a submarine optical cable accessing the relay, converting an uplink analog optical signal into an uplink digital optical signal and performing amplification transmission on the uplink digital optical signal; the end covers are arranged on the two ends of the pressure bearing cylinder; and the photoelectric separation module and the photoelectric processing module are arranged in the pressure bearing cylinder. According to the underwater optical signal amplification relay with the demodulation function provided by the invention, the amplification transmission is performed on the downlink analog optical signal, the uplink analog optical signal is demodulated into the uplink digital optical signal, and then the amplification transmissionis performed on the uplink digital optical signal, thereby improving the signal quality of remote transmission of the submarine optical cable and effectively solving the difficulty that the transmission distance of the analog optical signal in the submarine optical cable is solved.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to an underwater optical signal amplification repeater with a demodulation function and a submarine monitoring system. Background technique [0002] The relay transmission system has become an indispensable means of communication in long-distance transoceanic communication. The underwater repeater is an important part of the submarine communication transmission system. The repeater has high requirements for safety and reliability. , and its service life is required to be more than 25 years. Due to the particularity of the marine environment, underwater repeaters have high technical requirements for volume, structure, materials, watertightness, airtightness and corrosion resistance. In addition, the repeater should have a small power consumption and run underwater for a long time, so it should also have good heat dissipation. The underwater repeater is an underwater communication...
