I was completely frustrated by the 802.3 Working Group’s lack of constructive
response to Walter Thirion’s plea for their help in clarifying the PMD objectives
at the thursday meeting. I believe that Walter was trying to re-center the debate on
the PMD objectives in order to break the impasse on their implementations.
I believe Walter was on the right track. I propose that the committee should debate
the objectives of the PMD’s to clearly identify the application space and cost considerations.
I offer the following as a point of departure.
Objectives for debate:
- support of installed (legacy) 62.5 and 50 micron multimode fiber to 300 meters.
- support of a low-cost short-reach fiber solution for the Internet Data Center, Central Office,
equipment room, and premise application to 300 meters (new installations).
Potential 10 Gb/s Ethernet customers addressing the committee have voiced strong
support for inclusion of a low-cost short-reach fiber objective to address the application space
of the Internet Data Center, the Equipment Room and the Central Office.
