Infinera is launching a set of end-to-end Digital OTN solutions to deliver the benefits of Infinera’s Digital Optical Networks combined with full compatibility with international OTN standards. Infinera is delivering Digital OTN solutions with new hardware and software.

OTN (Optical Transport Network) is a set of standards developed by the ITU-T specifying optical network architecture and specific signal structures and interfaces to promote transparent multi-service transport, improved network performance and greater interoperability for wavelength division multiplexing (WDM) networks. OTN promises to simplify, flatten, and reduce capital and operating cost in optical networks.

The Infinera DTN supports OTN switching at every node, enabling grooming and switching of OTN-encapsulated client services to maximize service reconfigurability and network performance monitoring throughout the network, for increased network bandwidth efficiency. The enhancements announced today add the capability to support native OTN end-to-end services from metro/edge networks across backbone/core networks and standard-compliant OTN networking across multiple operator networks.

By enhancing Infinera’s Digital Optical Networks architecture to support OTN service interfaces, an Infinera network offers significant benefits over a conventional OTN transport-only WDM network. With integrated bandwidth management, an Infinera network offers OTN switching in the network core. This enables capacity in the network to be used more efficiently, minimizing wasted bandwidth. In addition, the implementation of OTN solutions in both the Infinera ATN and Infinera DTN platform enables end-to-end aggregated OTN hand-offs throughout the network, from metro edge to metro core to long-haul core.
