10 Gb ethernet range

Hi,

I am trying to specify a 10Gb backbone for a campus. The fibre links between buildings would ideally be multi mode OM4. What is the maximum range that HP SFP+ has achieved with this.

The website details only 300m but I think this is for OM3. Cisco claim 400m for their optical deviecs on OM4.

Thanks, Brian.

Re: 10 Gb ethernet range

OM4 is reasonably recent; I have really heard very little about it.

 

The connector interface type (SFP+, XFP, X2, etc) will not have a bearing on the distance. It is only the specific properties of the optics - SR in this case. 

 

http://en.wikipedia.org/wiki/Multi-mode_optical_fiber says SR = 400m+

 

But speak to your supplier/HP rep and confirm this!
