  • Fiber Optic Communication Principles Wavelength Division

    Fiber Optic Communication Principles Wavelength Division

    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. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. Each wavelength, or “channel,” carries an independent data stream, allowing bandwidths up to 400. Wavelength divi-sion multiplexing allows transmissions on tbe fiber to use different colors of light (each color represents a different wavelength over which light propagates). WDM increases the capacity and efficiency of fiber optic.
