A unit of frequency that is equal to one billion cycles per second, 109 Hertz Graded-Index Fiber design in which the refractive index of the core is lower toward the outside of the fiber core and increases toward the center of the core; thus, it bends the rays inward and allows them to travel faster in the lower index of refraction region This type of fiber provides higher bandwidth capabilities for multimode fiber transmission
The gigahertz, abbreviated GHz, is a unit of alternating current or electromagnetic (EM) wave frequency equal to one thousand million hertz (1,000,000,000 Hz) The gigahertz is used as an indicator of the frequency of ultra-high-frequency (UHF) and microwave EM signals and also, in some computers, to express microprocessor clock speed
(GHz) Typically a term referring to the speed that your CPU processes information (I E ; an Intel P4 operating at 2 4GHz) One billion cycles per second High-speed radio frequency applications transmit in the gigahertz range
