OIF Launches Flex Coherent DWDM Framework Effort, Elects New Officers

Members of the Optical Internetworking Forum (OIF) are working to specify a framework for Flex Coherent DWDM Transmission in the application fields of long haul, metro, and data center inter-connection. The framework will build upon work the OIF completed for 100G LH DWDM and provide guidance for 400G.

“We’ve discussed the hardware implications of SDN for a couple years now,” said Junjie Li, of China Telecom and OIF board member. “We need to move away from fixed performance transceivers in order to provide Service Providers with a flexible solution, complete with software ‘knobs’ that can be dialed-in to achieve the desired performance.”

Dynamic networks require flexibility in reach, data rate, and spectral efficiency. This can be accomplished through the following flexible transceiver attributes: modulation formats, symbol rates, and number of subcarriers. Flex Coherent DWDM will outline a software-defined optics ecosystem that initially leverages past and current OIF projects for tunable lasers, high bandwidth PMQ modulated transmitters and integrated coherent receivers. The Flex Coherent DWDM Transmission will start with the following modulation formats suitable for different scenarios; QPSK, 8QAM, 16QAM for long haul and metro applications and 32QAM, 64QAM for data center inter-connection applications.

Board Elections

The OIF announced the results of its recent leadership elections, welcoming Peter Landon of BTI Systems as the chair of the Networking & Operations Working Group committee for 2-year term.

Newly elected to the Board of Directors are Ian Betty of Ciena for a 2-year term, Tom Issenhuth of Microsoft for a 2-year term and Mike Tessaro of Qorvo for a 1-year term. Junjie Li of China Telecom was re-elected to the board for a 1-year term. John McDonough of NEC America will serve as president. Dave Brown of Alcatel-Lucent continues to serve as VP of Marketing and Dave Stauffer of Kandou Bus continues to serve as secretary/treasurer.

OIF Day at Huawei Technologies

In conjunction with the Forum’s recent quarterly meeting in Shanghai, the OIF and Huawei Technologies hosted a day of interactive and educational workshops featuring OIF and Huawei Technologies subject matter experts. Topics covered included OIF projects and technical work, intelligent optical networking, and 400G. The exclusive event was focused on helping attendees understand system vendor challenges and strategies, strengthening member/executive support for the OIF and establishing an input and validation process for strategic/project planning.

About the OIF
The OIF facilitates the development and deployment of interoperable networking solutions and services. Members collaborate to drive Implementation Agreements (IAs) and interoperability demonstrations to accelerate and maximize market adoption of advanced internetworking technologies. OIF work applies to optical and electrical interconnects, optical component and network processing technologies, and to network control and operations including software defined networks and network function virtualization. The OIF actively supports and extends the work of national and international standards bodies. Launched in 1998, the OIF is the only industry group uniting representatives from across the spectrum of networking, including many of the world’s leading service providers, system vendors, component manufacturers, software and testing vendors.
