Re: [10GMMF] task2 & task4 launch study table of launch recs rev 0.4
Jonathan, I think the tables are becoming clearer now. I have these comments:
(a) The OFL BW for OM1 fiber should be 160/500 ....
(b) Is there a specific meaning to "primary" & "alternative", and should that be given in another footnote.
(c) The previous use of encircled flux has been to quantify in some way the mode power distribution of launches with VCSELS. Our experimentation and modeling corresponding to options 1 & 2 has been with single mode launches equivalent to a DMD launch with some offset. If the launch is intended for small spot launches a la the DMD maybe we can do a better job specifying it, and if the launch is intended to be generalized to allow multimode mode VCSELS maybe we need to do some modeling of that like we did for OM3. (plus experiments if possible). (This comment applies to the offset launch specification not the center launch)

Thanks John
I'll compile references in in a final version of the 'summary of progress' slide set tonight;
there is a placeholder for that in the rev1 version (which includes suggestions from today's conference call) which was sent out to the reflector for comment about ten minutes ago !
best wishes Jonathan

Jonathan,
Thanks for compiling this table. Can you provide references to the any work showing the equivalence of the offset launch and the corresponding proposed encircled flux specifications, and of the centered launch and corresponding encircled flix specifications, in both cases for OM1, OM2, and OM3? Thanks.

Jonathan,
With 3 separate tables, as in the current materials, the universal launch can be presented in a much simpler way now that it is not commingled with the other launches. Given that it is universal, one need not call out fiber types or bandwidth, so the table simply collapses into one column with a title cell above a spec cell.

With attachment !
As discussed by the group today I've revised the single table into 3
options as proposed by David Cunningham and agreed by those on the call
includes 6um radius spec for OM1 as proposed by Joerg, and an attempt at
an advisory sentence in note 2 as proposed by Lew
feedback very welcome, ASAP
thanks for the input from all into today's call
best wishes
Jonathan
