WDM Module
Wavelength division multiplexer is splitting and merging of wavelength optical passive components, is to use the low insertion loss of the fiber resources, through WDM combined wave, combine different wavelengths of light on an optical fiber transmission, at the receiving end, the wavelength division multiplexer of partial wave will be different light carrier to separate different signal multiplexing method respectively.
