The passive wavelength division multiplexing equipment is composed of a multiplexer and a color optical module. By using wavelength division multiplexing technology, optical signals of different wavelengths are combined on an optical fiber for transmission, thereby saving optical fiber resources. It has the advantages of fast deployment, small size, low power consumption and low cost.
