Next-generation 200 Gb/s and 400 Gb/s MMF PHYs call for interest

The following request for agenda time for a Next-generation 200 Gb/s and 400 Gb/s MMF PHYs call for interest has been received from Robert Lingle. It will be discussed at the IEEE 802 LMSC November 2017 Plenary meeting in Orlando, FL, USA.

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

Links comprising multimode fiber cable and VCSEL-based transceivers have played a key role in implementing 40 Gb/s and 100 Gb/s Ethernet in data centers for short reach. The continual growth of bandwidth demand has driven evolution of higher Ethernet speeds, most recently with 200 Gb/s and 400 Gb/s Ethernet, as demonstrated by related IEEE 802.3 projects over the past 4 years. To better support the installed base of MMF cables and to reduce the relative cost of short reach links, we request a call for interest to assess support for a Study Group to develop the PAR and CSD for next-generation 200 Gb/s and 400 Gb/s PHYs over fewer MMF pairs than existing Ethernet projects.

The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 6th November. A call for interest consensus building meeting has been scheduled to occur from 20:30 to 21:30 on the evening of Tuesday 7th 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 9th November.
