WDM Optical Receiver

Optical receivers, in contrast to laser sources, tend to be wideband devices. Therefore, the demultiplexer must provide the wavelength selectivity of the receiver in the WDM system. WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM).OverviewIn, wavelength-division multiplexing (WDM) is a technology which a number of signals onto a single by using different (i.e., colors) of. A WDM system uses a at the to join the several signals together and a at the to split them apart. With the right type of fiber, it is possible to have a device that does both s.
