Open Eye Consortium 53Gbps-per-lane multi-mode SR4 and single-mode LR PAM-4 specs available to public

The Open Eye Consortium multi-source agreement (Open Eye MSA) has announced two new specifications targeted for 53Gbps-per-lane applications: SR4 for 100m reach over a multi-mode fiber and LR for 10km reach over a single-mode fiber, complementing the existing 200Gbps FR4 spec. The single-mode LR spec is to be finalized and available at the 22nd China International Optoelectronic Exposition (CIOE 2020) in Shenzhen, China (9-11 September).

The MSA defines the requirements for analog PAM-4 (4-level pulse amplitude modulation) solutions for 50G SFP, 100G DSFP, 100G SFP-DD, 200G QSFP, 400G QSFP-DD and OSFP modules.

Due to the growing demand for data, wireless, enterprise and data-center network managers are continually looking for ways to drive lower power, smaller size and lower costs. The Open Eye MSA’s new specifications will provide customers with an alternative to higher-power and higher-cost digital signal processing (DSP)-based solutions. These specs are suitable for 53Gbps SFP28 long-reach (LR) and 200Gbps QSFP short-reach (SR) optical module designs for next-generation 5G wireless, enterprise and data-center networking applications.

The Open Eye MSA aims to accelerate the adoption of PAM-4 optical interconnects scaling to 50Gbps, 100Gbps, 200Gbps and 400Gbps by expanding on existing standards to enable optical module implementations using less complex, lower-cost, lower-power and optimized analog clock & data recovery (CDR)-based architectures in addition to existing DSP architectures.

For interested parties to learn more about the Open Eye’s MSA mission and latest technical information, a whitepaper is available to view and download from the Open Eye Consortium’s website.

In addition, the Open Eye MSA is hosting two webinars (available to the general public) aimed at introducing network planners and optical module developers to the new technology:

  • ‘Reduce Cost, Power and Latency with Open Eye MSA based Optical Connectivity’ (26 August) - targeted for data-center, enterprise and telecom network architects. Presenters overview the benefits of the Open Eye MSA approach enabling low-cost, low-power and low-latency optical modules for 200Gbps and 400Gbps connectivity deployments.
  • ‘Reducing the Cost of 200Gbps and 400Gbps Optics using Open Eye MSA compliant Chipset Solutions’ (2 September) - targeted for manufacturers of optical modules. The Open Eye MSA approach is a natural evolution relative to today’s high-volume optical nodes, enabling users to scale to next-generation Baud rates. Presenters overview chip-set and test solutions for implementation of modules based on Open Eye MSA specifications.

The Open Eye MSA also says that its membership has grown to 37 with the addition of Credo Semiconductor, Fuji Xerox and Lumentum.

Promoters include: Applied Optoelectronics Inc, Cambridge Industries Group (CIG), Juniper Networks, Luxshare-ICT, MACOM Technology Solutions Inc, Molex, and Semtech Corp.

Contributors include: Accelink, Anritsu, Broadex Technologies, Cloud Light Technology, ColorChip, Credo Semiconductor, Fujitsu Optical Components, Fuji Xerox, HG Genuine, HiLight Semiconductor, InnoLight, Inopticals, Keysight Technologies, Lumentum, Marvell, Maxim Integrated, MultiLane, O-Net, Optomind, Renesas, SAMTEC, Sicoya, Source Photonics, Sumitomo Electric, TE Connectivity, Tektronix, TRUMPF and two more members.
