WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM). Coarse WDM provides up to 16 channels across multiple transmission windows of silica. Wavelength division multiplexing (WDM) is a technology for increasing the transmission capacity of optical fiber communications by sending multiple data channels simultaneously through a single fiber, each on a different wavelength of light. Applications: Short to medium reach (up to 80km), cost-sensitive metro access, enterprise networks, point-to-point links. Pros: Very. CWDM stands for Coarse wavelength division multiplexers. These are modules that increase the amount of bandwidth the fiber optic system will carry by transmitting multiple signals at various wavelengths along the fiber optic cables. Learn all about CWDM, how it differs from DWDM, and whether a CWDM solution is right for your business's network.
