What is Wavelength Division Multiplexing?

Wavelength Division Multiplexing (WDM) is an optical transmission technique that carries multiple data channels on a single fiber by assigning each channel a distinct optical wavelength within the fiber’s usable spectrum. Expanded Explanation 1. Technical Function and Core Characteristics WDM transmits several independent optical signals over one fiber by using different wavelengths, or colors, of light as separate channels. Multiplexers combine these wavelengths at the transmitter, and

A glossary entry defines a term and stops there. It doesn't show where the term is actually being used or written about. We track and link every article that covers it.
