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

Hi Ali

 

Because of some off-line consensus building discussions, I happen to have the LightCounting numbers and calculations for 40GE module cost ratios which may be of interest to the Study Group.

The LightCounting cost ratio for 40GE-LR4 to 40GE-SR4 in 2012 is about 6x. Since the LR4 cost includes CFP modules, a more accurate market cost ratio using only QSFP+ modules for 40GE-LR4 and 40GE-SR4 will be about 4x in 2012. This is also consistent with the LightCounting projection of the cost ratio of SFP+ 10GE-LR to 10GE-SR as below 3x in 2012. In practice, these ratios vary considerably depending on individual market circumstances.

 

I will also assume a MTP terminated 8x parallel MMF to LC terminated duplex SMF cost ratio of 4x.

 

Based on this, we can conclude that the cost cross-over point for parallel SMF solution over WDM duplex SMF solution is ~400m. This is consistent with your experience that several of your customers would like to push the SR4 link reach beyond 100/150m.

Talking to several customers they are saying they are currently deploying 40G-SR4 with 100 m reach on OM3 or 150 m on OM4,

they want to support the same reach on 100G-SR4.  Due to high cost of 40G-LR4 optics, in some case the 40G-SR4 links in 

proprietary application are pushed beyond 100/150 m reach, I expect you might have seen similar requests.

 

Thanks,

Ali

Hello Jeff

 

Thanks for the kind word.

 

Regarding the two conclusions on page 2, the second, “A 100 m OM4 …” is intended to include MMF cabling cost.  While I may not have reliable data on the relative costs of 100 m of OM4 OM3, I believe reducing the fiber count from 20 to 8 covers a large range of premium.  I will try to clarify my intent.

 

Thanks again,

 

John

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 17^th 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
