Dear All,
802.15 SC Maintenance reviewed the PARs and CSDs and has 1 question / comment:
802.3dj PAR and CSD
802.3dj PAR states:
5.2.b Scope of the project: Define Ethernet MAC parameters for 1.6 Tb/s. Define physical layer
specifications, and management parameters for the transfer of Ethernet format frames at 800 Gb/s and
1.6 Tb/s over copper, multi-mode fiber, and single-mode fiber physical medium dependent (PMD)
sublayers, based on greater than 100 Gb/s signaling technologies. Use this work to define derivative
physical layer specifications and management parameters for the transfer of Ethernet format frames at
200 Gb/s and 400 Gb/s.
802.3dj CSD states:
Distinct Identity
The proposed amendment will define derivative physical layer specifications
from those developed for 800 Gb/s and 1.6 Tb/s Ethernet to address copper,
multi-mode fiber, and single-mode fiber specifications, based on a reduced
number of physical lanes, for 200 Gb/s and 400 Gb/s Ethernet.
Economic Feasibility
In consideration of installation costs, the project is expected to use proven and familiar media, including electrical backplanes, twin-axial copper cables, multi-mode optical fiber cabling, and single-mode optical fiber cabling.
Under “Economic Feasibility”, multi-mode optical fiber cabling is struck out. Is this intentional and, if so, why?
Regards, Phil
