In order to know more better about the parameters of the CWDM, and show the professional knowledge when having business , we share the information with you today.

Waht is CWDM SFP?
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.

The color of the CWDM module is colorful, with a total of 18 wavelengths, every 20nm is one wavelength, include forward wavelength and post wavelength.
Forward wavelength: 1270nm, 1290nm, 1310nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1450nm; transmit distance is 20km/ 40km
