[802.3_DIALOG] Call for interest - Hybrid (optical / electrical) automotive Ethernet data links

Dear Colleagues,

The following request for agenda time for a call for interest has been received from Carlos Pardo. It will be discussed at the IEEE 802 LMSC November 2019 Plenary meeting in Waikoloa, HI, USA. If you have any questions please get in touch with either Carlos Pardo <carlospardo@xxxxxxxxx> or myself directly.


Discussions and presentations to the Multi-Gigabit Automotive Optical PHY Study Group have highlighted that the majority of automotive Ethernet links will have asymmetric peak and aggregate data rates in the two link directions. For example, a link to a camera primarily carry the image data in one direction, with the reverse direction primarily carrying the much lower data rate camera control data. There is significant interest from Study Group participants in using multi-gigabit optical fiber to carry traffic in one link direction but use a significantly lower speed electrical path in the opposite link direction, optionally allowing power to be provided over the electrical balanced conductors. This Call for Interest is to consider expanding the scope of the Multi-Gigabit Automotive Optical PHY Study Group to also allow a PAR and CSD to include adding specifications for hybrid (optical/electrical) automotive Ethernet data links.


The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 11th November. A call for interest consensus building meeting has been scheduled to occur from 19:30 to 20:30 on the evening of Tuesday 12th 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 14th November.

David Law, Chair, IEEE 802.3 Ethernet Working Group
