Uplinking 3750Es using 62.5 micron fiber
I have read that it is possible to uplink 3750Es using the 62.5 micron fiber cable instead of having to replace all your existing fiber runs with 50 micron. I also read that this is only possible if you are going shorter distances then 300m and if going longer distances it is recommended to change over to 50 micron. Does anyone have experience with this? How has it worked out for you? I was not able to find any write up on this on Cisco's site so I am kind of hesitant about it. Thanks for any help.

62.5 micron is fine for short links. For 10GBe it is rated up to 82ft. 50 micron comes in 3 flavors OM2, OM3, and OM4. They basic difference is the distance they will perform at 10GBe. -

Yes sorry forgot to mention that we would be using the 62.5 for 10GB. So 82ft? Hmmm we may have a problem then -

I'd save yourself a lot of headaches and just go with the vendor recommendation.An expert is a man who has made all the mistakes which can be made. -

The standard right now is OM3 and OM4 for MM cabling. To support future 40GB and 100GB deployments you should redo your runs with the good stuff, or switch everything to single mode.
