[802.3_NGEPON] 答复: [802.3_NGEPON] Clarifying questions on guo_3ca_1_0716.pdf

[Yong Guo <guo.yong3@xxxxxxxxxx>]

Dear Ed,

Thank you very much for your comments, 

For your clarifying questions, following are my quick answers.

1. Yes, in the table of page 5, minimum of 6dB ER is indicated. However,
AVPmin, OMAmin and sensitivity are all based on ER=9dB. I'm just keeping
the same style with the Table 75-5 in 802.3. Please correct me if I'm wrong.

2. Some of these contributions are listed as follows, I will update them
as back up slides before the meeting. The proposed downstream sensitivity
is based on 9dB ER.

3. Yes, actually all of our lab results are better than -28dBm. We also
had test from our 25G-PON prototype, results show better than -27dBm. We
believe performance could be further improved in the future. However, in
contrast, we don't think increasing minimum average power more than 3dBm
for EML is feasible without using postamplifier. This is actually an issue
that where you choose to put more pressure, transmitter side or receiver
side. We think improving the sensitivity is much easier than increasing
the transmitter power. Larger output power with amplifier can be used to
compensate WM insertion loss. 

Thank you very much, and look forward to seeing you next week.

Yong

Yong Guo,
 
Thanks for your interesting contribution guo_3ca_1_0716.pdf,  
 
I do have a few clarifying questions:
 
On slide 5:
1.       In the table ER=6 dB is indicated, while in the notes ER=9 is indicated.  Could you please clarify?  (I think you used 9 dB, and the 6 is a typo).
2.       It is stated that “-27dBm sensitivity using 25G APD is feasible based on results from multiple contributions”.  Could you please cite those contributions?  Also, could you please confirm that this is for ER=9 dB.
3.       Are these lab results, or do you consider -27 dBm would be a viable commercial value for our standard (i.e. high yield, over temperature and end-of-life).  
 
Thanks for your help.

Subject: [802.3_NGEPON] contributions for the July meeting
 
Dear Colleagues,
 
 
We have 33 contributions to be considered at the meeting next week.
It will take me some time to create the html page with all the links. But the files are now available as a directory listing at the URL below, in case you want to start reviewing the presentations sooner.

Also, if you have submitted a file and don't see it uploaded, please let me know ASAP.
 
Regards,
Glen
