Wavelength-division multiplexing
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single

This phenomenon occurs due to the varying interactions between the light and the fiber material at different wavelengths. For fiber optics with glass fibers, we use light in the infrared region which has wavelengths longer than visible light, typically around 850, 1300 and 1550 nm. The most important elements of optical communication are a transmission medium with extremely low optical attenuation and a highly stable, long-life light source that operates with a small current. Their wavelength adaptation relationship is the first step in optical fiber system design.
