Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical communication, and in particular, to an optical signal transmission method, device, and wavelength selective switch. Background technique [0002] With the rapid growth of users' demands on network traffic and bandwidth, operators have more and more urgent demands on the intelligent scheduling function of the underlying wavelength division multiplexing (Wavelength Division Multiplex, WDM) network in the optical communication network. [0003] During the transmission of optical signals, the power of optical signals may experience nonlinear gain or attenuation, which may cause various problems in network management. If the power of the optical signal is too small, the optical signal-to-noise ratio of the signal at the receiving end is too low. Therefore, during the transmission of the optical signal, the power of the optical signal needs to be adjusted within the set power rang...
