Re: [8023-10GEPON] [PRX-U3] Power budget for PRX-U3
Dear Ken-Ichi,
I think the pdf file is with problems. It requires addition of Japanese fonts and even then there are some wierd quirks inside. Please prepare it again or send over the ppt.
Regardign the assumptions for the power budget - I suppose me and Frank used the same sensitivity when working on the PRX-U3. The penalty allocation was selected differently since we did not have any feedback on this particular topic.
Cheers

Assunto: Re: [8023-10GEPON] [PRX-U3] Power budget for PRX-U3
Dear Marek,
I am sorry for late response.
I and Otaka-san would like to propose the revised power budget
for PRX30.
Attached please find the PPT document.
(1)I think NTT has already proposed IEEE_Rx_Str_Sen_OMA as
-27.6 dBm. Basically, I would like to use this value.
(2)If PRX_U3 use a DFB-LD, TDP and ECP (eye closure penalty)
should be reduced. (I recommend those values be 1.4 dB.)
(3)In comparison of the sensitivity difference to confirm
possible dual-rate receiver technologies, I think we should
use ideal receiver sensitivities such as IEEE_Rx_Sen_OMA.
Best regards,
Ken-Ichi
