All – conversation is good, and highlighting an issue that needs to be addressed. There appears to be a trend of
I can see a path to relating Item A to be within scope of Beyond 400 GbE effort. I am not seeing that same path for Item B. John From: Ted Sprague <tsprague@xxxxxxxxxxxx> I’m used to the second definition (independent PHYs grouped in the same MSA, common interface for management). In the first case, the module may support a unified mode or multiple individual modes – but only the second is referred to as ‘breakout’. Thanks Ted From: David Ofelt <00000d9f58951f93-dmarc-request@xxxxxxxxxxxxxxxxx> CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe. I think there are two different concepts that end up being colloquially referred to as breakout. The first is that case you detaiil below- a set of parallel media lanes that can be grouped in various ways- either as a single unified PHY or as a number of slower PHYs. The other case is a module that happens to hold a number of PHYs that are completely independent- like a QSFP-DD/OSFP module that has 4 x 100GBASE-LR optics. I’m Ok with declaring that “breakout” just covers the first case and your list is a good start at scoping the definition, but if we do that, I’d like us to figure out a name for the other case. I find that when I talk to people about modules- it is important to clearly address both cases, since many folks have only one of the cases in mind and conversations can get confusing.
-- DaveO From: John D'Ambrosia <jdambrosia@xxxxxxxxx> [External Email. Be cautious of content] All, As I explore the scope for the Beyond 400 GbE effort, I have been having a number of conversations related to “breakout” While we all discuss it – I have never seen some actual formal definition that is agreed upon within 802.3. So I would like to get some input. I am going to start with breakout actually does and solicit input before proposing some definition to potentially use. I see break out of the following –
FR / LR / ER optics – I don’t see as being part of breakout. Thoughts?
