Two strands of fiber are used for a single fiber optic connection to increase the overall bandwidth of the connection. This allows for higher data rates to be transmitted over the same amount of cable, as the two strands can be used to transmit signals in both directions simultaneously. Additionally, using two strands can help to improve reliability, by providing a redundant path in the event of a cable failure.
