The adjacent channels of CWDM 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 54x25x7mm, which Is about 3 timessmaller than that of standard CWDM package.
CCWDM optical module Is widely used In the fields of coarse wavelength division multiplexing system, PONnetwork, ATV link, telecommunication network enterprise network, metropolitan area network WDM system,4G/communication moble system, 100G solution, access network, metropolitan area network WDM system,optlcal fiber tools and so on.
