OIF Approves Agreement on Polarized Multiplexed Quadrature Modulator
Starts 112G inside Multi-Chip-Module Project, Google’s Bikash Koley speaks at Q1 Meeting
Members of the Optical Internetworking Forum (OIF) recently passed an Implementation Agreement (IA) for an optical integrated Polarization Multiplexed (PM) quadrature modulator for coherent applications with nominal symbol rates up to 64GBaud. The agreement supports the 16QAM modulation format for 400G applications.
“As we go to higher data rates, we need higher performing optical components that maintain a reasonable level of complexity.” said Karl Gass of Qorvo and the OIF’s PLL Working Group – Optical Vice Chair. “These components are targeted for 400G applications. RF bandwidth is the highest priority for this project.”
The forum members also started the CEI-112G in MCM project to support interconnect within Multi-Chip-Modules (MCMs). In addition to the CEI-112G-VSR specification that is being developed, there is a need to support high rate interconnect amongst large logic devices as well as to small driver devices within an MCM.
Members have also started a maintenance project to produce amendments to the User Network Interface (UNI) 2.0 and External Network to Network Interface (E-NNI) 2.0 specification documenting the extensions for support of OTN rates higher than 100G. Adding these extensions to UNI 2.0 and E-NNI 2.0 will facilitate vendor interoperability. The project seeks to assist the IETF as it develops the required routing and signaling extension by providing a description of the Byond100G data-plane and the operations to be controlled by GMPLS.
Also at the forums’ Q1 meeting, Bikash Koley, distinguished engineer and director of network architecture, engineering and planning at Google was invited as a guest speaker and presented on the Zero Touch Network.
Following the quarterly meeting in San Jose, a well-attended FlexE workshop was held. An overview of the completed and in process FlexE projects was provided, along with presentations and discussion on the future direction of FlexE. The workshop started with a summary of the FlexE 1.0 Implementation Agreement and was followed by an overview of the active FlexE 2.0 project. Speakers and panelists include Luca Della Chiesa, Cisco; Tad Hofmeister, Google; Maarten Vissers, Huawei; Dave Ofelt, Juniper; Tom Issenhuth, Microsoft; Scott Irwin, MoSys and Stephen Trowbridge, Nokia.
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.
