What is WDM?

Wavelength Division Multiplexing (WDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. It's commonly used in telecommunications to increase bandwidth and capacity on existing fiber optic networks.
