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.
Masterclass Series – The Optical Internetworking Forum” session
is being held Tuesday, May 21, 2019 from 08:00 – 10:00. 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
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
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”
