3. TP3 planning for Vancouver
Reviewed proposal from Mike
I've captured the following comments on my presentation... (new version attached)
In general I was proposing that we focus on TBD's. Work to an agreed deadline, and agree to use voting if necessary in order to close off issues and proceed.
ACTION: Each member review timeline and come to the next meeting ready to accept or reject
p3 Nick W: signal characterisation and measurement ... shouldn't that at TP3 itself and not as shown coming out of ISI block with filter
p5 Tom L: Slide misses the fact we have agreed the OMA value and SNR required at TP3 (Tom, My notes here were abit vague ... is this right?)
p6. Discussed outstanding work.
Key issues which were raised:-
PIE-D has variables associated with it (rise time, sigma^2, ZF vs MMSE calculation) - how do we handle that?
Different launches will produced different fiber sets and PIE-D distributions - Do we need to emulate different fiber IPRs or can we just use
different PIE-D distributions to represent results for different launches?
What would be the best approach, synthesis, selection, or measurement?, these terms need defining as used in the context or our discussion:-
- by synthesis we meant developing an algorithm which could generate 3 IPRs for any given PIE-D
- by selection we meant ranking a fiber set (Monte Carlo or 108) by our chosen Metric and then selecting appropriate channels to emulate
- by measurement we taking known fibers that are "appropriate" and then measuring either their IPR or their soft waveform at the Rx
ACTION: Each member to consider these approaches and come the next meeting ready to select our chosen technique.
p7. Timeline
ACTION: Tom and Piers agreed to work towards closing off jitter on our Nov 30 call
ACTION: Sudeep kindly agreed to look at PIE-D vs BT filters for our informative test. Aim is to remove TBDs on 7 Dec call
Time line needs to have Comment resolution deadline added ... Jan 7
Jan 4 meeting may not work as it will be first day back fo many? due to Jan 3 being a public holiday
4. TP3 Jitter testing Tom L.
Tom got agreement on two comments he will now submit:-
i) on a low frequency jitter test
ii) on an informative note to say that either Phase or Frequency modulation can be applied.
Tom and Piers still working on pk-pk UI figure for high frequency test.
5. Walk in items
Discussion on above and below the line items in Link budget. No changes just clarifications.
Any comments/corrections please get back with me.
Best Regards
Mike
