10GBASE DWDM Ethernet SFP + Fibre Optic Transceiver Made in China

SFP+ DWDM 1540.56nm 40km is a DWDM SFP+ optical transceiver module.

DWDM is Dense Wavelength Division Multiplexing. DWDM CWDM and WDM Transceiver Module are all based on the same concept of using multiplexing wavelengths on single fiber, but differ in the spacing of the wavelengths. DWDM MSA standard wavelength spacing is 0.8nm, for exp. by C Band MSA, there are 39 DWDM channels from 1540.56nm~ 1530.33nm. C-Light supplies DWDM SFP+ XFP modules for upto 80km fiber transmitting.
