Note

Multimode cables are used to send more than one signal at a time over shorter distances. They are generally less expensive and easier to work with because the core diameter is much wider (usually either 50/125 or 62.5/125 micron) and the tolerance for alignment isn't as critical as it is for single mode. They are used for most general data and voice transmissions up to 550 meters.

Single Mode cables on the other hand are used for much longer distances, up to 50 times as long as multimode fiber. Since the core is much smaller in diameter (usually 9/125 micron) only one signal can be sent at one time. This also takes away the possibility of cross-signal distortion. Single mode cables are used in applications such as digital cable TV or across a large college campus.
