OIF Marks Progress in Pluggable Coherent Modules, OTN, Transport SDN

The Optical Internetworking Forum announced a new, second project for a pluggable coherent optics transceiver (CFP2) module, saying standardization of a micro Integrated Coherent Receiver (ICR) will enable component manufacturers to quickly ramp up production while also reducing the cost and time to market for high volumes of pluggable modules.

Following its quarterly meeting, the OIF also cited progress on projects addressing thermal aspects, CEI-56G, E-NNI multi-domain recovery, OTNv3, and transport SDN:

  • The OIF Physical Layer Users Group is working to specify the surface smoothness and flatness of optical modules, which are key elements for thermal management by helping to improve heat dissipation.
  • For CEI-56G, simulations of this proposed interface were presented to members of the Physical and Link Layer (PLL) working group. The CEI-56G work effort potentially supports both narrower 100Gbps as well as 400Gbps efforts.
  • The E-NNI Recovery Amendment adds extensions to the E-NNI to allow automated backup from failure or maintenance in multi-domain carrier networks, a critical feature of the optical control plane.
  • The OTNv3 Amendment adds updates to the E-NNI to support the latest OTN control plane standards, now supporting rates from 1Gbps up to 100Gbps.
  • The Carrier completed documenting an initial set of carrier requirements for Transport SDN, providing a framework for Transport SDN in a multi-domain carrier network and identifying requirements on signaling network, control plane and management for deploying SDN in a reliable, secure and high performance manner. OIF members are reviewing this document before it is available to the public.

In addition, the OIF announced the election of Evelyne Roch of Huawei as the Networking & Operations Working Group chair and plans for workshops on Next Gen efforts and Transport SDN in early 2014.  New Members to date in 2013 include Google, KAIST, Mellanox, Optelian, Ranovus, Sandvine, TELUS and US Conec.
