The invention provides an optical transmission system and method applied to a seabed observation network, and the system comprises a shore station OTN service layer processing module which is used for converting different service electric signals into optical signals with different wavelengths; a shore station OTN optical path layer processing module which is used for converging the optical signals with different wavelengths and then outputting the optical signals to a backbone optical cable; an underwater junction box OTN optical path layer module which is used for converting the converged optical signals input by the backbone optical cable into optical signals with different wavelengths; and an underwater junction box OTN service layer processing module which is used for converting the optical signals with different wavelengths into electric signals and outputting the electric signals. According to the optical transmission system and the optical transmission method applied to the submarine observation network, optical path communication management is realized by using the OTN equipment, ultra-large-capacity broadband transmission is realized, different services are independently separated, channel resources can be flexibly scheduled, the stability is relatively high, automatic error correction and fault recovery can be realized, and the reliability can be improved through looped network establishment.

Description

technical field [0001] The invention relates to the technical field of optical transmission networks, in particular to an optical transmission system and an optical transmission method applied to a seabed observation network. Background technique [0002] At present, the submarine observation network system uses an optical cable system laid underwater from the shore end to the underwater node. When the number of primary and secondary junction box nodes of the submarine observation network reaches a certain scale, the required communication capacity is quite large. Astonishing. The traditionally suggested single-wavelength optical path, that is, a simple optical routing topology, will cause high delay and high packet loss for long-distance, high-bandwidth optical network transmission, and cannot perform network monitoring and forward error correction functions.

Problems solved by technology

The traditionally suggested single-wavelength optical path, that is, a simple optical routing topology, will cause high latency and high packet loss for long-distance, high-bandwidth optical network transmission, and at the same time cannot perform functions such as network monitoring and forward error correction.

Therefore, the quality of optical transmission cannot meet the needs

At the same time, in a sea area, different distributed nodes will carry different customer services, such as military industry, civilian use, scientific research, etc. From the perspective of business management, traditional ordinary optical transmission networks cannot achieve flexible scheduling of channel resources.
