Commonly available optical fibers are generally divided into multimode and single-mode categories. The graded-index multimode fibers have core diameters of 50, 62.5, 85 or 100microns, and the conventional single-mode fibers have mode field diameters of 8.8, 9.5 or 10.0microns. Historically, multimode fibers have been used for transmitting light near 825 and 1300 nm and single-mode fibers have been used near 1310 and 1550 nm.
