  • External  Laser Small Form-Factor Pluggable (ELSFP) Module
    The External Laser Small Form-Factor Pluggable (ELSFP) IA is the second project initiated under the umbrella of the Co-packaged Framework Project.  The ELSFP IA will define a future proofed external laser source form factor to support co-packaged optical modules. . The form factor is a front panel pluggable module which employs a blind-mate optical connector located at the rear of the module for eye-safety considerations. The IA will define interoperability for mechanical, thermal, electrical, as well as for the optical connectors.  For more information, contact Jeff Hutchins, Physical and Link Layer WG, Co-Packaging Vice Chair.

  • APIs for Transport SDN
    As the industry looks at Transport Software Defined Networking (SDN), there is a lack of definition for how User Applications interact with Network Applications and Resource Functions. The programmability of Transport SDN requires some of the internal interfaces used by ASON in the past to become open. The expected outcome for this project is a series of Application Program Interface (API) documents addressing: Service Request, Connection Request, Topology, Link Resource Manager, Path Computation, and other APIs identified by the SDN Framework document. For more information on this project contact Jonathan Sadler, Networking Interoperability Working Group Chair.
  • Storage & Optical Connection Coordination
    Transaction failures caused by jitters, intermittent disconnection and bit errors over the unstable DCI links occur frequently in the financial industry, where storage and optical devices are commonly used. To leverage the advantages of fast fault detection of optical connections, it is helpful to coordinate storage and optical connections in the DCI network. This new project will describe the scenarios, key technical requirements, gap analysis to enable the coordination between storage devices and optical connections, and applicability of generic multi-layer protection solutions. For more information on this project contact Jia He, Networking & Operations Working Group Chair.

    This project will generate amendments to the UNI 2.0 and E-NNI 2.0 specifications including the routing and signaling extensions for Beyond-100G G.709 and will not allocate code points or define message formats.  Work on codepoint and message formats will be developed collaboratively with the IETF.  For more information on this project contact Jonathan Sadler, Networking Interoperability Working Group Chair.
  • Digital Twin Optical Network as an Enhanced Network Operation
    This project describes the motivation of introducing digital twin (DT) concept in the optical network. It specifies the DT optical network as an enhanced network operation and its applications. It also describes the relevant interface requirements, Input/output data requirements, which helps with the gap analysis of the exiting standards. This project proves a start of standardization activities of digital twin optical network. For more information on this project contact Jia He, Networking & Operations Working Group Chair.
