I respectfully disagree. I have several multimode installations in excess of 1500' working with no problem on multimode fiber. Of course it does depend on the the speed you want to run on there and the quality of the fiber, installation and equipment.
According to the BICSI Telecommunications Distribution and Design Manual, which I realize is not the bible but certainly a valid source of information:
As a general guideline in premises applications for backbone cabling:
*62.5/125 um or 50/125 um multimode optical fiber is recommended for distances under 2km (1.2 miles) and data rates up to 155 Mbs.
*single mode fiber is recommended for for greater distances or higher data rates
Now if you are going to push it to gigabit ethernet, it is a bit more critical, however General for one makes a Gigabit fiber for up to 600 meters and there are others with similar products.
Short simple fiber hops are obviously easy to do, you can get almost any fiber and any tranceivers and make it fly. As you approach the upper limits of distance and/or bandwidth, one should give some serious thought to having the circuit designed and tested when installed to insure that you get what you were intending.
It is only my opinion, based on my experience and education...I am always willing to learn, educate me!
