[802SEC] IEEE P802.3cz draft PAR and CSD response - Multi Gigabit Automotive Optical PHYs

Dear EC members,

In support of subclause 9.2 'IEEE 802 LMSC Approval' of the LMSC Operations Manual please find below the required information in respect to the IEEE P802.3cz Standard for Ethernet Amendment: Physical Layer Specifications and Management Parameters for Multi-Gigabit Optical Automotive Ethernet PAR for consideration at the March 2020 plenary.

Best regards,
  David

[1] Draft PAR and CSD responses:

Draft PAR: <https://mentor.ieee.org/802-ec/dcn/20/ec-20-0010-00-00EC-ieee-p802-3cz-draft-par-response.pdf>
Draft CSD: <https://mentor.ieee.org/802-ec/dcn/20/ec-20-0011-00-00EC-ieee-p802-3cz-draft-csd-response.pdf>

[2] Explanatory technical background material:

Applications in automotive industries have begun the transition of legacy automotive networks to Ethernet to support Advanced Driver Assist Systems. This has generated a need for data rates greater than 1 Gb/s in the automotive environment. Optical fiber has been used in automotive applications both for Ethernet and other protocols. This project will complement other 802.3 projects working on specifications for electrical media operation at rates greater than 1 Gb/s in the automotive environment. The number of cameras in vehicles is increasing as is the camera data rate with movement to higher resolution video. Optical data links are applicable to both the vehicle network backbone as well as connection of selected devices where location or other factors favor using an optical link

[3] Status of the development of the PAR:

The draft PAR and CSD responses are pending IEEE 802.3 Working Group approval at the March 2020 plenary.
