Re: [802.3_400G] Breakout Functinoality Objective

Jonathan,

Thank you for the summation of my concern. 

The selection of a PHY will be based on its ability to meet the objectives. For example, if there are two PHY/PMD proposals where #1 provides a significant cost and implementation benefit but #2 provides breakout capability, then this objective could be used to defeat #1 in favor of #2.

Maybe the question the study group needs to answer is: Is breakout a critical requirement for 400G that we wish to exclude proposals that do not support it?

Thanks,
Brad

To avoid locking out an otherwise compelling technology option….

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
