We are building a new Residence Hall on our campus. The question has come up on what type of fiber to install SM verse MM. The backbone is 1GB and the distance is 2500 feet. It looks like Single mode fiber will deteriorate a 1GB connection at 300 meters and is pushing us to use Single mode fiber. What hardware or application limitations will we have by using single mode. There will be 3750's at each end of this fiber run.
