100 Gb/s Lambda call for interest


The following request for agenda time for a 100 Gb/s Lambda call for interest has been received from Mark Nowell. It will be discussed at the IEEE 802 LMSC November 2018 Plenary meeting in Bangkok, Thailand.

If you have any questions please get in touch with either or directly.


Ethernet has a successful track record of reusing and leveraging technology in order to enable new cost-optimized solutions for broad market adoption. Recently, both the IEEE 802.3bs and IEEE 802.3cd Ethernet projects defined optical interfaces based on 100 Gb/s PAM4 per lane optics for 500m reaches on single-mode fiber. This technology enables a lower component count implementation that can lead towards a lower cost solution.

The successful industry adoption of 100 GbE is resulting in higher volumes and continuing cost pressures on optical interfaces and the hyper-scale data centers, being aggressive adopters of cost-effective solutions, are looking to enable the next generation of lower cost solutions for 400 Gb/s Ethernet interfaces.

At this time, no IEEE 802.3 Ethernet specifications exist for greater than 500m reaches on single-mode fiber using this advanced technology. This Call For Interest is a request for the formation of a Study Group to explore the potential market requirements and feasibility of extending 100 Gb/s PAM4 per lane optical technology to longer 100 Gb/s and 400 Gb/s Ethernet reaches.


The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 12th November. A call for interest consensus building meeting has been scheduled to occur from 18:30 to 19:30 on the evening of Tuesday 13th November. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 15th November.
