What is the L band DWDM?
WDM technology can be divided into WDM, CWDM, and DWDM according to different wavelength modes. The wavelength range defined by ITU-T, The CWDM range is 1271 to 1611nm based on ITU-T G 684.2. Considering the fiber attenuation of the 1270-1470nm band in the application, the band of 1470~1610nm is usually used. The channel space of […]
