The Open Eye Consortium has established a Multi-Source Agreement (MSA) with the aim to standardize advanced specifications for lower latency, more power efficient and lower cost optical modules.

The MSA aims to accelerate the adoption of PAM-4 optical interconnects scaling to 50Gbps, 100Gbps, 200Gbps, and 400Gbps by expanding upon existing standards to enable optical module implementations using less complex, lower cost, lower power, and optimized clock and data recovery (CDR) based architectures in addition to existing digital signal processing (DSP) architectures for datacenter interconnects over single-mode and multimode fibers.

Minimizing the need for digital signal processing in optical modules has many advantages including significantly lowering latency, power consumption and cost.

The Open Eye MSA consortium’s approach is a natural evolution relative to today’s high-volume optical nodes, enabling users to scale to next generation baud rates. The initial Open Eye MSA specification will focus on 53Gbps per lane PAM-4 solutions for 50G SFP, 100G DSFP, 100G SFP-DD, 200G QSFP, and 400G QSFP-DD and OSFP single-mode modules. Subsequent specifications will aim to address multimode and 100Gbps per lane applications.

MACOM and Semtech Corporation initiated the formation of the Open Eye MSA with 19 current members in Promoter and Contributing membership classes. Promoters include Applied Optoelectronics Inc., Cambridge Industries (CIG), Color Chip, Juniper Networks, Luxshare-ICT, MACOM, Mellanox, Molex and Semtech Corporation.

Contributors include: Accelink, Cloud Light Technology, InnoLight, Keysight Technologies, Maxim Integrated, O-Net, Optomind, Source Photonics and Sumitomo Electric. The initial specification release is planned for Fall 2019, with product availability to follow later in the year.
