Re: [10GMMF] Loss of worst case test configuration
task 2 reviewed its presentation for the channel ad hoc session at the upcoming September interim ; During discussion on the standard link and the justification for connector offset it was suggested that it would be very valuable to show the justification behind the figure of 7 micron worst case offset; Would you be able to make a 1 or 2 slide summary of your work to be included in the task 2 update slides ?
If you're willing, could you send a power point version (without company logos and disclaimers) to me, which I can add to the presentation. David Cunningham is doing the same for the work he did - it works out very nicely that 2 experts in the field take different routes to arrive at similar numbers.

Subject: [10GMMF] Loss of worst case test configuration
In the discussion for the worst case test configuration there was some discussion about the loss of connector transverse offsets if the 70/70% launch condition (which should represent the so called steady state power distribution) is applied.
I calculated the connector loss vers transverse offset for various launch conditions including the 70/70% launch.
It turns out that the loss with the 70/70% launch is somewhat larger than the 23Ám offset launch. Therefore the total loss of our worst case test configuration would be larger than 1,5dB if such 70/70% launch would be applied.
It is common agreement today to use the defined offset patchcord and I do not want to change that but I want to share the results for the sake of completeness because it shows the sensitivity of our selection on the launch conditions.
