Abstract
The present invention discloses: when a first laser in N lasers is switched to a second idle laser in M lasers, a wavelength of a wavelength-selective optical element to which the first laser is coupled is adjusted from a first wavelength to a second wavelength, and the second wavelength is different from the N wavelengths. Similarly, when a first optical receiver in N optical receivers is switched to a second idle optical receiver in M optical receivers, a wavelength of a wavelength-selective optical element to which the first optical receiver is coupled is adjusted from a first wavelength to a second wavelength, and the second wavelength is different from the N wavelengths.
