WDM: Wavelength Division Multiplexing

Wavelength Division Multiplexing (WDM) is a technology that uses optical signals on different wavelengths to increase the capacity of fiber optic networks in order to handle a number of services simultaneously. WDM conversion modules have one strand of single mode fiber coming into them. They transmit and receive on the same fiber strand. The MIL-RC3xW13 transmits at 1310 nm and receives at 1550 nm. The MIL-RC3xW15 transmits at 1550 nm, and receives at 1310 nm wavelengths. One of each is required at opposite ends of the fiber to work properly.
