Description

technical field [0001] The present application relates to the application field of Internet technology, and in particular, relates to an optical fiber transmission system and a signal transmission method. Background technique [0002] Long-distance or metro optical cable resources are becoming more and more precious, and the design of optical transmission systems pursues higher transmission capacity and lower unit bit transmission cost. However, due to the closed nature of the current optical transmission system, usually only equipment from one manufacturer can be used on a pair of optical fibers, and equipment from different manufacturers generally cannot coexist in the same pair of optical fibers. In order to break the lock-in of manufacturers, a technology of alien wavelength (Alien Wavelegnth) has appeared now, that is, the wavelength of one manufacturer is transmitted in the transmission system of another manufacturer. However, the existing OTN transmission system is a...
