What is the distance Limitation on 100Mbps Fiber for Single Mode and Multi Mode?

Multimode 100 Mb/s (FDDI or Fast Ethernet) is limited to 2 km (1.2 miles) by the dispersion of the fiber and the chromatic dispersion limits of the LED in the fiber. This holds for both 62.5/125 micron fiber and 50/125 which exists in some older installations. Single mode links are avaialble for over 20 km (12 miles) or more. All single mode fiber for 1310 nm is the same, with a core diameter of about 8-9 microns and cladding diameter of 125 microns.
