Leading Optical Companies Form Terabit BiDi MSA to Enable Cost-Effective Data Center Connectivity in order to:

  • Promote a common set of optical interface specifications based on 100 Gb/s per lane BiDi technology in order to advance the development and adoption of high density 800 Gb/s and 1.6 Tb/s multimode pluggable optical interfaces.
  • Facilitate development and adoption of 800 Gb/s and 1.6 Tb/s high density optical interconnects for data center and cloud networking that include multimode links with a focus on low-cost, low-power, proven and available optical component technologies.
  • Achieve cost-optimal and faster deployments of multi-mode 100 Gbps/lane signaling on high density 25.6 Tb/s and future 51.2 Tb/s switches by leveraging the existing significant parallel multimode fiber (MMF) installed base.

Specification

The Terabit BiDi MSA will publish a common set of optical interface specifications and recommendations to facilitate the development and interoperability of 800 Gb/s and 1.6 Tb/s capable BiDi optical interfaces. If you would like to support these efforts with our founding members - please .

About Us

The Terabit BiDi MSA will promote a common set of optical interface specifications based on 100 Gb/s per lane multi-mode technology in order to advance the development and adoption of high density 800 Gb/s and 1.6 Tb/s BiDi pluggable optical interfaces.

We are combining forces with like-minded industry leaders to promote the use of both new and existing physical interface standards which we believe can offer advantages in time-to-availability, diversity of supply base, and cost.

Contact

This MSA is open to interested parties who would like to support this effort. For more information about this MSA or membership please contact us at today.

FAQs

Q: Why does the industry need Terabit BiDi MSA?
A: Promoting the reuse of well-established and industry-standard high volume parallel multi-mode infrastructure used in 40 Gb/s and 100 Gb/s Ethernet SR4 deployments will enable a healthy ecosystem of partners and accelerate time to market of 800 Gb/s and 1.6 Tb/s multi-mode optical interconnects. The Terabit BiDi MSA will specify 100 Gb/s per lane optical specifications that can support 800 Gb/s and 1.6 Tb/s applications.
Q: Is the Terabit BiDi MSA dependent on other outside standards activity?
A: The Terabit BiDi MSA will promote interface solutions based on multi-mode 100 Gb/s per optical lane technologies and architectures, for use at 800 Gb/s and 1.6 Tb/s, several examples of which are already well defined or are under development in the IEEE 802.3 or by other MSAs. Where necessary the Terabit BiDi MSA will also draw from and refer to form-factor specific MSAs like the OSFP, QSFP-DD and OSFP-XD MSA and the Common Module Interface Specification (CMIS).
Q: Will this be compatible with the upcoming 800 Gb/s and 1.6 Tb/s Ethernet specifications?
A: Yes, it will build upon the base foundational Ethernet specifications (including PCS) that are in development.
Q: What are the anticipated use cases of the Terabit BiDi MSA?
A: The Terabit BiDi Multi-source Agreement will address end user needs for next-generation Ethernet network infrastructure based on 25.6 Tb/s and 51.2 Tb/s switch ASICs, by promoting fully interoperable optical links leveraging existing and proven IEEE standard 802.3cm and 802.3db optical interfaces with end-to-end KP4 FEC on multimode fiber.
Q: Can other companies join the Terabit BiDi MSA?
A: Yes. Interested parties are welcome to to join as a contributing member of this MSA.
