Re: [802.3_100GNGOPTX] - MMF Ad Hoc - 17th Jan meeting timing



If copper fits in a QSFP+ then of course it will also fit into larger forms, and it is not restricted.  But for access switch ports, which is where copper would be deployed, then higher density is a big driver due to blade server density trends.

Paul

 

What is the basis for your statement that 100G copper is restricted to QSFP+?

John,

Thanks so much for this exploration, which addresses just the sort of questions that have been puzzling me.  In fact I was wishing for a good comparison to SR10 just today.  I see some good parallels to Ali’s work emerging. 

 

While it is not clear to me how much support exists for FEC behind optical interfaces, it would be quite helpful if your material could address how the addition or substitution of FEC affects the numbers.  If the outcome is that FEC allows QSFP+ form factor, then that seems to enable common forms between fiber and copper media, which to me look like a big advantage to the user and vendor, if not for near-term aggregation switch ports at least for future server and access switch ports. 

 

I also request the same clarification as Jeff.  If you need assistance with cabling cost particulars, I can help.  I have been analyzing cabling costs in my efforts to add such analysis to the solution analyzer spreadsheet.  A reasonable assumption for the cost of SR4 cabling is ~40% of SR10 cabling cost.

 

Regards,

Paul

John,

 

Great effort.

 

On your slide 2, can you make clear whether your conclusion includes the MMF cabling cost?

 

Jeff

Hello Jonathan

 

Attached is a draft presentation prepared for the Newport Beach meeting.  Although I’m not sure of my schedule/availability for Tuesday morning, I would appreciate feedback from any who care to offer some.

 

Have MMF ad hoc conference contact details for Tuesday been distributed?

 

Regards,

 

John

Dear all

A reminder  that there will be an MMF ad hoc meeting on Tuesday 17th Jan 2012, from 8am to 10.30 am PCT, in order to minimize the overlap with a concurrent OIF meeting.

If you have material to present, please let me know before hand.

 

Thanks

Jonathan
