Wavelength Division Multiplexing

Coarse Wavelength Division Multiplexing (CWDM) is the use of the Fiber Optical Multiplexer to different wavelengths of light signals multiplexed to a single optical fiber for transmission
Characteristics
It has low polarization Related Loss, High Wavelength Isolation and Low Insertion Loss.
Applications
It is appliable for CWDM System, PON Networks and CATV Links.
