WDM combines a series of optical signals carrying information but with different wavelengths into a beam and transmits the beam along a single optical fiber; and separating the optical signals with different wavelengths by a certain method at the receiving end. The technology can transmit multiplex signals on one optical fiber at the same time, each path of signal is transmitted by light with a certain specific wavelength, namely a wavelength channel, and the optical wavelength division multiplexing generally adopts a wavelength division multiplexer and a demultiplexer (also called a wave combination/wave division device) which are respectively arranged at two ends of the optical fiber to realize the coupling and the separation of different optical waves. The principle of these two devices is the same. The main types of the optical wavelength division multiplexer include a melting taper type, a dielectric film type, a grating type and a plane type. The main characteristic indexes are insertion loss and isolation. Generally, since the wavelength division multiplexing device is used in the optical link, the increase in the loss of the optical link is referred to as the insertion loss of the wavelength division multiplexing. When a wavelength is transmitted through the same optical fiber, the difference between the power at the input end and the power mixed in the optical fiber at the output end in the branching filter is called isolation.
