[802SEC] IEEE P802.3bs draft PAR and CSD modification - 200 Gb/s and 400 Gb/s Operation

Dear EC members,

In support of subclause 10.2 'IEEE 802 LMSC Approval' of the LMSC Operations Manual please find below the required information in respect to a PAR modification request for IEEE P802.3bs Standard for Ethernet Amendment: Media Access Control Parameters, Physical Layers and Management Parameters for 200 Gb/s and 400 Gb/s Operation for consideration at the March 2016 plenary.

Best regards,

[1] Draft PAR modification and CSD responses:

Draft PAR modification request: <>
Draft modified CSD responses: <>

[2] Explanatory technical background material:

During the development of IEEE P802.3bs 400 Gb/s Ethernet, it was decided to develop 50 Gb/s optical and electrical signaling. With this signaling available, a family of Ethernet rates, based on multiple instantiations of 50 Gb/s, e.g. 50 Gb/s Ethernet, 100 Gb/s Ethernet, 200 Gb/s Ethernet, and 400 Gb/s Ethernet is emerging. The development of 200 Gb/s Ethernet physical layer specifications equivalent to the existing 400 Gb/s Ethernet specifications is being added to this project.

[3] Status of the development of the PAR:

The draft PAR modification and CSD responses are pending IEEE 802.3 Working Group approval at the March 2016 plenary.
