All -
I have been asked to lead a group to study tradeoffs between cost and
performance specifications for TP2. We need to begin immediately with the
objective of bringing data to the September meeting. I apologize for not getting
this email out sooner, but I have been on vacation.
Reducing cost is an important motivation for this work. However, it is
clear that the optical power budget is also tight. Rx sensitivities are
challenging, there is some pressure on worsening fiber models, EDC
implementation budgets are still being discussed, and transmitter
powers need to be managed to control reliability, safety, EMI, etc. Therefore, I
recommend that the focus on this study is less about promotion of low cost
optics than it is about developing a set of tradeoff data for TP2 that the
larger committee can use to balance and optimize against TP3 and cable plant
specifications.
The starting point is slide 17 of lindsay_01_0704 (see attached - the
entire presentation, given by Paul Voois, can be found at http://grouper.ieee.org/groups/802/3/aq/public/jul04/lindsay_1_0704.pdf).
There are 5 main areas of required work:
More details are given in lindsay_01_0704. The last item, at a high level,
should consist of (set(s) of) recommended specs, test methods, penalties, and
cost impact data for TP2. The other 4 items would provide support
information.
To begin:
Thanks,
