IPoDWDM


IP over DWDM is a technology used in telecommunications networks to integrate IP routers and network switches in the OTN.
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 specified by ITU-T G.709/Y.1331 or Super FEC functionality defined in ITU-T G.975.1.

Benefits

This approach saves network components including shelves, processors, interfaces cards and hence it permits to reduce the power consumption, OPEX and CAPEX.
This approach brings also a simplification of the network, eliminating the SDH/SONET intermediate layer.

Multivendors

A DWDM network can be implemented using different vendor technology from the IP devices as long as they support alien wavelength transmission specified by ITU-T G.698.2.
