DWDM Wavelength ITU Channels Chart: A Complete Guide (2024)

WebCWDM supports up to 18 wavelength channels transmitted through a fiber at the same time. To achieve this, the different wavelengths of each channel are 20nm apart. DWDM, supports up to 80 simultaneous wavelength channels, with each of the channels only 0.8nm apart. CWDM technology offers a convenient and cost-efficient solution for shorter ... WebCollectively, CWDM and DWDM are commonly referred to as xWDM. The main difference between the CWDM and DWDM technologies is how the channels are spaced along the electromagnetic spectrum. While DWDM wavelengths are typically 0.8 nm apart, CWDM wavelengths are 20 nm apart. As a result, CWDM is limited to a maximum of 18 channels. WebFeb 16, 2024 · Cisco DWDM cards support 32 wavelengths in the C-band and 32 in the L-band, as shown in Table 1-3 and Table 1-4.
