Abstract
A method and an apparatus for monitoring a wavelength channel are disclosed. The method includes: performing optical-to-electrical detection on an optical signal on a wavelength channel, to obtain an electrical signal; obtaining a frequency spectrum of the electrical signal; determining a first parameter M according to an equation M=NAC, where NAC represents an alternating current component of the frequency spectrum of the electrical signal; and if M is greater than a preset first threshold, determining that the wavelength channel includes a real service signal. According to the method and apparatus, an erroneous configuration or operation of a network management system can be avoided.
