Crowd Spacing in Coarse Wavelength Division Multiplexing CWDM

Home / Crowd Spacing in Coarse Wavelength Division Multiplexing CWDM

The wide spacing accommodates the uncooled laser wavelength drifts that occurs as the ambient temperature varies. This capability enhances system design flexibility and efficiency, making CWDM a valuable technology in modern broadcast and production environments. Wavelength Division Multiplexing (WDM) is an optical transmission technique that allows multiple independent optical signals to be carried over a single fiber by assigning each signal a different wavelength. Applications: Short to medium reach (up to 80km), cost-sensitive metro access, enterprise networks, point-to-point links.
