Abstract
A method for adjusting a filtering bandwidth of an optical device includes: acquiring a modulation bandwidth of a first optical signal and s modulation bandwidth of a second optical signal, where the first optical signal is an optical signal input into a first wavelength channel of an optical device, the second optical signal is an optical signal input into a second wavelength channel of the optical device, and the second wavelength channel is adjacent to the first wavelength channel; comparing the modulation bandwidth of the first optical signal with the modulation bandwidth of the second optical signal; and according to a result of comparing the modulation bandwidth of the first optical signal with the modulation bandwidth of the second optical signal, adjusting a filtering bandwidth of at least one wavelength channel of the first wavelength channel and the second wavelength channel.
