IPoDWDM

IP over DWDM (IPoDWDM) is a technology used in telecommunications networks to integrate IP routers and Switches in the OTN (Optical Transport Network). This approach safes network components including shelves, processors, interface cards and hence it permits to reduce the power consumption and OPEX (Operational expenditures).

A true IPoDWDM solution is implemented only when the IP routers and switches  support ITU-T G.709. In this way IP devices can monitor the optical path and implement the transport functionality as FEC (Forward Error Correction) specified by ITU-T G.709/Y.1331 or Super FEC functionality defined in ITU-T G.975.1.

This approach realize also a simplification of network, eliminating the SDH/SONET intermediate layer. See for example,.

A DWDM network can be realized using different vendor technology of the IP as far as they support Alien Wavelength transmission as it is specified by ITU-T G.698.2 specification,.
