8ch CCWDM Module

8ch CCWDM Module

4/8 Channels CCWDM Mux Demux, Single Fiber, Side A, Optional Connectors and Housing Compact coarse wavelength division multiplexers (CCWDM Mux) is the mini version of CWDM Mux. Compared with traditional CWDM technology, CCWDM technology uses free-space optics platform which can significantly improve optical performance, in a package less than 1/4 the size of conventional CWDM modules. Main advantages of CCWDM Mux are high wavelength accuracy and stability, low insertion loss, high isolation and low PDL(polarization dependent loss). It's protocol and rates transparent supporting such applications as the CWDM system, PON networks, and CATV Links.

8ch CCWDM Module

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.

Optico 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.
