WDM Technology of Things

Wavelength Division Multiplexing (WDM), A WDM technology that multiplexes several optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber, also called wavelength-division duplexing, as well as multiplication of capacity. Transmission from combined sources is separated at … Continued
