Re: [802.3_100GCU] Discussion of Objectives



Looks good,but maybe there should be something about which wire type we aim for in the cable statement.
......cables (AWG 26) for... or something similar.

Subject: [802.3_100GCU] Discussion of Objectives

All,

I wanted to try and foster some discussion on the reflector regarding objectives for the project to help all focus their planning of presentations for March. 

 

So what do we appear to have consensus on so far?

a)      We are in a  study group looking at 100GbE over backplane and copper twin-ax

b)      Legacy support indicates broad market potential would be aided by 4 lane solutions

 

What appears to need further consensus building?  Well the big ones would seem to be reach for both backplane and cu cabling objectives. 

 

So if we can combine where we appear to have consensus with what we need to resolve, the following two statements could be used as strawmans for objectives for the group to work towards (leaving the reach #’s as variables for now):

 

·         Define a 4-lane 100 Gb/s PHY for operation over copper traces on improved FR-4 for links consistent with lengths up to at least “X” m.

 

·         Define a 4-lane 100 Gb/s PHY for operation over copper twin-axial cables for links consistent with lengths up to at least “Y” m.

 

Feedback?

 

John
