All of the data centers I go to (which are carrier hotels mainly) are all single mode – multimode is prohibited in some locations (as a way of standardizing). That said, individual cages in some data centers you can still run multimode but definitely not between cages/locations/floors

All BIDI interfaces need single mode as best as I can tell. That might have changed my decision to use multimode in a few cases. These days, I don't think there is any good reason to use multimode any more. bp <part15sbs{at}gmail{dot}com> On 5/27/2015 12:07 PM, Nate Burke wrote: Is there a MultiMode BIDI SFP? I need to run a connection across a warehouse, they have 3 pair of multimode fiber, but all 3 are already in use. They won't let me tunnel connections together, because that would be touching 'their' network, but I could probably talk them into using only a single Strand, to let me have one. Googling around hasn't yielded any results yet, but I'm still searching. Any other passive deivce to get 2 connections on one/pair Multimode fiber? Nate
