WDM Modules

Product List


WDM is the abbreviation of wavelength-division multiplexing. WDM modules can multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelenths of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity.


WDM modules has many types: CWDM, DWDM,EWDM ,etc.

Coarse wavelength-division multiplexing (CWDM

Dense wavelength-division multiplexing (DWDM)

Edge wavelength-division multiplexing (EWDM)
