Re: [802.3_100GNGOPTX] SMF Ad Hoc



Hi All,

I agree with John's point below, but would like to suggest a minor contextual addition.

The role of the Task Force is to identify the best alternative by weighing all available parameters under consideration which include latency, performance, complexity/simplicity etc.

Clearly, cost, size and power were used as our justification and they should continue to receive priority in the overall analysis, but we want to keep all relevant parameters on the table for discussion.


Regards,

Dan

Hello Jeff

 

Unfortunately, justification of the 500m SMF objective for the project is explicitly cost, size and power.  While I can sympathize with other with other issues, I would need a lot of help explaining why cost, power or sized was sacrificed.

 

Regards,

John

All,

 

We have to make sure that the assumption of the use of FEC is explicit.  Although we might argue not to count the cost of the FEC encoder/decoder itself, we do need to understand the impact on cost that the use or lack of use of FEC poses.  It is good thus to make analysis of the impact on cost of designs presuming the use of FEC versus designs presumed NOT to use FEC.  I see the potential lack of need of FEC as one of the technical advantages of parallel single mode as well as market-acceptance advantages.

Hi,

 

As previously announced, there is an SMF Ad Hoc meeting starting at 8:00 am Pacific today Tuesday 18 December.

I have currently received two requests for presentations, so the draft agenda is:

 

·         IEEE patent policy reminder

o   http://www.ieee802.org/3/patent.html

 

·         Approval of the draft minutes from 4 December call

 

·         Presentation

o   PSM4 Technology & Relative Cost Analysis Update                                                                           Jon Anderson, Oclaro

o   Basic Study on Receiver Bandwidth Requirement  for Discrete Multi-tone Modulation    Masato Nishihara, Fujitsu

 

·         Discussion

 

·         Future meetings (next opportunity - 8 Jan)

 

I hope to post both presentations on the SMF Ad Hoc web page  just prior to the meeting.
