Pete, ‘refinements’ to 4x25G 10km baseline in COLE_01_0708 which
increases Rx sensitivity by 0.4dB over that proposed in COLE_01_0508 which I
agreed with. Not 100G but 40G: The budget for 10km 4x10G COLE_03_0708
has -11.5dBm OMA Rx sensitivity per lane which is 1.1dB tougher than the I know these numbers are subject to change at
this stage but I’d like to understand the underlying rationale for the proposed
changes in more depth than the time for Q&A in Alan Tipper Gennum Corp / Tacitis Ltd. From: Pete Anslow

[mailto:alan.tipper@xxxxxxxxxxxxx] Hi Pete, I’d certainly be interested
in joining in an informal discussion over these specs – I was a bit
concerned when going through the uploaded presentations. See you in From: Pete Anslow
[mailto:pja@xxxxxxxxxx] Dear Task Force members, During the process of discussing draft versions of contributions for the
Denver meeting aimed at filling in the details of the 100GBASE-LR4 and ER4
optical parameter tables it has become clear that there are differing opinions
over the detailed power budgets. Since the Task Force has not yet adopted baseline presentations for all
of its agreed objectives, it seems unlikely that there will be sufficient Task
Force meeting time available next week to enter in to detailed discussion on
optical parameter values for 100GBASE-LR4 and ER4. However, as the Editor
of the clause containing these PMDs, I will be tasked with creating the first draft of it during the period between the If there is sufficient interest, I will confirm the time and location
of the discussion during Tuesdays Task Force meeting. See you all in Nortel Networks UK Limited, External +44 1279 402540 ESN 742 2540 Fax +44 1279 402543 |
