CWDM SFP is a kind of optical transceiver combined with CWDM technology. It is an economical and high efficient network connection solution, widely used in campus, data centers and the Gigabit Ethernet and fiber channel (FC) in metropolitan area network and other network applications.

CWDM SFP with different wavelengths
Generally the CWDM SFP has eight wavelength ranges from 1470nm to 1610nm. In order to better determine the wavelength of the use of the Gigabit Ethernet channel mapping when using, so we will use different colors to match and distinguish these CWDM SFP. That's why the SFP modules of different colors have different applications. Take Cisco as an example, following list the wavelength and color of different CWDM SFP.
