OIF’s Optical Masterclass Series at NGON to Include Updates on 400ZR, Common Electrical I/O, Flex Ethernet & SDN Projects

Fremont, Calif.—May 8, 2019 – At NGON, May 21-23, 2019, OIF experts will kick off the Optical Masterclass Series with a comprehensive update on its 400ZR, Common Electrical I/O (CEI)-112, Flex Ethernet (FlexE) and Software Defined Networking (SDN) projects.

“OIF’s interoperability solutions are vital to the global network and with many of the key network operators in attendance, NGON is the ideal platform to provide updates on OIF’s work in 400ZR, CEI, FlexE and SDN,” said Dave Brown, Nokia and OIF Director of Communications.

The “Optical Masterclass Series – The Optical Internetworking Forum” session is being held Tuesday, May 21, 2019 from 09:00 – 11:00 (NEW TIME AS OF 5/16). Brown and Karl Gass, OIF Physical & Link Layer Working Group Vice Chair, Optical, will discuss how OIF is assuring interoperability in open, agile, next-generation optical networks and provide updates on crucial industry projects.


OIF’s 400ZR project is critical in facilitating the reduction of cost and complexity for high bandwidth data center interconnects and promoting interoperability among optical module manufacturers. This Implementation Agreement (IA) will specify an interoperable digital coherent 400ZR interface targeted at short reach (80 km or more) DWDM amplified noise limited links and unamplified loss limited links.


The CEI project update will include discussion of the multiple 112 Gb/s interfaces being defined by OIF including CEI-112G MCM, XSR, VSR, MR and LR. Applications of these 112 Gb/s interfaces include die-to-die, die-to-OE (optical engine) on package, chip-to-module, chip-to-chip and chip-to-chip long reach over backplane and cables.


OIF continues to lead in FlexE aggregation architectures through its newest FlexE 2.1 project for FlexE over 50GbE PHY applications, an extension to its FlexE 2.0 Implementation Agreement (IA). FlexE 2.1 will specify a 50G FlexE frame and multiplexing format and will address FlexE applications with lower bandwidth needs and provide an implementation foundation for applications including the access layer of the future 5G mobile network.


In November 2018, OIF announced the launch of “Requirements for Integrated Packet Optical SDN.” The project outlines requirements for a multi-layer SDN reference architecture as a use case for packet optical transport networks. It will generate functional requirements, a reference architecture and use cases for packet/optical networks guided by the vision to enable agile, open network solutions that simplify operations and optimize resource utilization.


The session will also include an update on the Integrated Coherent Transmit-Receive Optical Sub Assembly (IC-TROSA) project that defines a standard optical component containing a complete coherent modem. The availability of highly integrated components accelerates the adoption of coherent transmission into additional markets.

Additionally, Gass will participate in Wednesday’s Plenary session, 09:30 – 10:10, “Present View: To the terabit & beyond – practicalities for coherent transmission.” Also on Wednesday, from 14:35 – 15:30, Brown will speak on the “Open Source Approach: Looking at disaggregation as a pathway for multi-vendor cooperation, interoperability and driving enhanced network interfaces” panel.
