A : Multi-mode fibers have larger cores (about 2.5 x 10.3 inches or 62.5 microns in diameter) than single-mode fibers and transmit infrared light (wavelength = 850 to 1,300 nm) from light-emitting diodes (LEDs). Yo­u hear ab­out fiber-optic cables whenever people ta­lk about the telephone system , the cable TV system or the Internet. Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection.
