Abstract
The present disclosure provides a calibration system for wavelength-division multiplexing (WDM), a WDM system, and a calibrating method for WDM. The calibration system includes heating devices, an optical sensor, and an electrical device. When the optical sensor receives no beam with energy exceeding a threshold value from a first channel, the optical sensor transmits a first signal to the electrical device. In response to the first signal, the electrical device is configured to control the one or more of the heating devices to heat one or more of channels. When the optical sensor receives a beam having energy exceeding the threshold value from the first channel, the optical sensor transmits a second signal to the electrical device. In response to the second signal, the electrical device is configured to control the one or more of the heating devices to maintain the temperature of the one or more of the channels.
