Compact Coarse Wavelength Division Multiplexing (CCWDM) is the use of the Fiber Optical Multiplexer to different wavelengths of light signals multiplexed to a single optical fiber for transmission, at the receiving end of the link, with the Fiber Optical Multiplexer fiber mixed signal is decomposed into different wavelengths signal, connected to the respective receiving device.we now offers a Mini CWDM (CCWDM) module that provides bandwidth capacity expansion for future network growth in one of the industry’s smallest packages.The compact CWDM modules are based on free space optics technology.it is available in 4-or 8-channel configurationsIt have lower overall insertion loss and better uniformity across the channels.Its compact size and unique carrier tray set it apart, making it easier to deploy in a variety of field situations.
