CWDM/DWDM ITU Channels Guide
CWDM / DWDM ITU Channel Guide
CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) enable carriers to deliver more services over their existing fiber infrastructure by combining multiple wavelengths on a single fiber.
We provide a line of CWDM/DWDM solutions and products that help alleviate your fiber exhaust in a reliable, cost-efficient way.

CWDM ITU Channels Overview
ITU-T G.694.2 defines 18 wavelengths for CWDM transport ranging from 1270 to 1610 nm, spaced at 20 nm apart. The complete CWDM grid is shown below.
Each CWDM channel is transparent to the speed and type of data, meaning that any mix of SAN, WAN, voice and video services can be transported simultaneously over a single fiber or fiber pair.

DWDM ITU Channels Overview
ITU G.694.1 standard DWDM region is from 1528.77nm to 1563.86nm that resides mostly within the C band. DWDM can have 100GHz (0.8 nm) wavelength spacing for 40 channels, or 50GHz (0.4 nm) spacing for 80 channels.
The complete channel grid for 100GHz DWDM is shown below.
