Re: [802.3_NGEPON] Wavelength comparison model

All,

 

Attached is the updated (1a) version of the wavelength plan comparison contribution. 

 

Changes:

Slide 9: updated scores after fixing the error that Alan pointed out (no qualitative difference)

Slide 10: clarified that Plan C TDM supports GPON co-existence for 25G only (not 100G)

Slide 13: added item to “next steps” based on today’s discussion on possible lower Ge/Si performance outside of O-band.

Alan,

 

Thanks for catching that bug!  Fixed spreadsheet is attached.

Hi Ed,

Great work; thank you!

I’m wondering about the formula for "Total weighted scores" cells D25:D30.  I thought each would have summed across columns “D” through “M”, but instead stop at column “L”.  It affects only one relative score: plan “A" vs. "C WDM".

All,

 

You can see our contribution on the updated wavelength plan comparison model here: harstead_3ca_3_1116.pdf.

 

Until last week the model showed Plans A, B, C about equal, similar to the original model.  But then based on feedback from Dekun and others, I separated out the criteria that did directly affect cost.  So I am a little embarrassed that the model now strongly indicates that the proposals that we have made “win” (slide 9).  However, I put those “other factors” now into a separate table (slide 10).  So the answer lies with the balancing of low cost with these other factors.

 

In case anyone is interested in playing with the model, I have attached the spreadsheet.  The weights in the yellow highlighted cells can be adjusted.
