Advantages of optical fibers over wires

  • low loss, so repeater-less transmission over long distances is possible
  • large data-carrying capacity (thousands of times greater)
  • immunity to electromagnetic interference, including nuclear electromagnetic pulses (but can be damaged by alpha and beta radiation)
  • high electrical resistance, so safe to use near high-voltage equipment or between areas with different earth potentials
  • light weight
  • signals contain very little power
