Re: [10GMMF] TP3 3-impulse test slides
Hello Nick, Bill,
Thank you for your interesting contribution. Sorry for not attending
yesterday call but I was flying...
Few comments:
1 - I agree on the proposed investigation on slide 2. The intention
is to design the three pulse test in order to create a worst case ISI
but still reasonable and compliant with Cam results on their fiber
database
2 - According to PIE-L and PIE-D the calculated curves are
symmetrical respect to pre/post cursor balance. This is true for FFE but
it is not for DFE. How should those curves change (becoming
asymmetrical) due to MMSE FFE+DFE architecture?
3 - Looking at slide 4 the interesting combination would be unity
spacing (1.0 UI) with 1/2-1-1/2 pre/post cursor balance and with
a=0.7~0.8. This would lead to about 5 dB optical penalty.
Best regards
Stefano
