The technology of WDM is nothing but wavelength division multiplexing the full form of WDM. This technology widely used in optical transport networks. The technical requirement is only that the laser is of very specific and that the DWDM full form is capable of distinguishing each wavelength without cross-talk. This article gives some application of WDM to give more information about WDM.
- In SONET network
- Dense WDM multiplexing allow to muxed and demuxed numbers of channel closer to one another to achieve greater efficiency
- FDM to the optical fiber
- Optical transport network
- Local exchange network
