The adjacent channels of CCWDM use parallel beams to cascade in free space instead of using optical fibers. Without the fiber used in cascade, the size of CCWDM package can reach 70x60x7mm, which is about 4 times smaller than that of standard CWDM package.
CCWDM optical module is widely used in the fields of coarse wavelength division multiplexing system, PON network, CATV link, telecommunication network, enterprise network, metropolitan area network WDM system, 4G/5G communication mobile system,100G solution, access network, metropolitan area network WDM system, optical fiber tools and so on.
