Re: [802.3_400G] Breakout Functionality Objective

I don’t see an issue with the wording as it is.   It isn’t saying that all variants have to support break out, just that the project as a whole should provide “appropriate support for breakout”.  Also the word “appropriate” means that the task force could determine that compelling arguments mean that breakout shouldn’t be supported.   What I think it does is legitimize us providing some weighting to potential variants that do support breakout.

Titan is in support of 4x100 as an initial PMD for 400Gbps.  The follows the trend of 4x10 and 4x25, and a migration path from CFP-CFP2-QSFP.  We are planning to present our ideas in the up-coming Nov and Jan meetings.

All,

Forgive the briefness of my last email, as I wrote it right after the minutes of the applications ad hoc.  Please see the following presentation for further input on my email below- http://www.ieee802.org/3/400GSG/public/adhoc/app/dambrosia_app_01_1013.pdf.

There could be much upside and little downside in including such an objective.   Meeting the objective could impact on PMD choices so the objective may need wordsmithing to avoid ruling out a useful PMD proposal that could not support breakout.

Subject: [802.3_400G] Breakout Functinoality Objective

 

All,

Per our call last week, what are the thoughts on the wording of this as a proposed objective –

 

Provide appropriate support for breakout functionality to 40G and / or 100G

 

There was some concern about potential impact or unintended consequences that people wanted to see this wording to discuss further.

 

Regards,

John
