Re: [802.3_400G] Breakout Functinoality Objective

Chris,

There are a number of ways to enable breakout, which could be via the architecture itself.  Also, note that there is no timing related to this.  It might apply to a future PMD.  And as Mike noted in his response, there is nothing in here that says all PMD variants have to support break out.

John,

 

Does this objective preclude a duplex SMF (pair) PMD, for example 8x50G or 4x100G WDM?

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
