ADVANTAGES AND DISADVANTAGES OF FIBER OPTICS BENEFITS OF USING LIGHT AND FIBER OPTICS 1. Tremendous bandwidth and consequent high data rates are easily achieved. An optical fiber system can easily support 100 Mbits/s; advanced systems are carrying beyond 1 Gbits/s. 2. The light pulses travel entirely within the fiber. They cause no interference, known as electromagnetic interference (EMI) and radio-frequency interference (RFI) in adjacent wire cables or optical fibers. 3. The optical fiber system is also immune to nearby signals and EMI/RFI, regardless of interference magnitude. An optical fiber placed next to an operating multi-mega-watt transmitter will perform as if the transmitter were turned off. There is no interference with adjacent optical fibers. 4. There is complete electrical isolation between the ends of the link. This eliminates ground loops (current that flows between two circuit grounds when they are not really at the same potential, although they should be so ideally), which affects performance, as well as the danger of shock at one end if there is a misconnection or failure at the other. 5.
