Abstract

The present application provides an optical domain compensation method, device, network management equipment, optical transmission system and medium. The method receives wavelength label information reported by at least one reconfigurable optical add / drop multiplexer (ROADM) node, and sets a wavelength selection switch (WSS) in each of the ROADM nodes; determines the transmission path of the optical signal according to the wavelength label information; configures the optical domain compensation parameters of each of the WSSs in the transmission path, and sends the optical domain compensation parameters to the corresponding WSS.
