Abstract

See full text

Disclosed are a method and an apparatus for selecting a wavelength by a wavelength tunable optical receiver. The method of selecting a wavelength of a wavelength tunable optical receiver includes: receiving, by the wavelength tunable optical receiver, an optical signal from a wavelength tunable optical transmitter; filtering, by the wavelength tunable optical receiver, the optical signal through a low frequency band electrical signal filter, and obtaining a low frequency signal; determining, by the wavelength tunable optical receiver, whether the low frequency signal is a valid signal based on a current value of the low frequency signal; and when the low frequency signal is the valid signal, obtaining, by the wavelength tunable optical receiver, an enable condition of a wavelength tunable optical filter through which the low frequency signal is selected, in which the low frequency signal includes a control/monitoring signal.
