Why are two strands of fiber used for a single fiber optic connection?

  • The two strands allow the data to travel for longer distances without degrading.
  • They prevent crosstalk from causing interference on the connection.
  • They increase the speed at which the data can travel.
  • They allow for full-duplex connectivity.
    Explanation:
    Light can only travel in one direction down a single strand of fiber. In order to allow for full-duplex communication two strands of fiber must be connected between each device.
