 A fiber optic cable consists of a thin glass or clear plastic fiber encased
 in a protective jacket. Signals are sent through the cable in form of light.
 There are two types of fiber optic cable: single-mode, which uses a single
-wavelength, and multimode, which uses multiple multiple wavelengths in the
+wavelength, and multimode, which uses multiple wavelengths in the
 same cable. Fiber optic cable is completely invulnerable to EMI, and has no
 detectable emissions. However, it and its associated equipment are expensive
 compared to other types of cable, and the most difficult to install. Single-mode
