Paper Abstract

A new technique to utilize a single optical fiber simultaneously for communication and sensing is proposed. The sensing channel's operation is based on the modulation of the interference pattern projected from the output end of a multimode optical fiber when the fiber is subjected to an external disturbance which changes its optical properties. It is demonstrated that the communication quality is not affected by the simultaneous operation of the sensing channel. Potential applications such as the protection of fiberoptic com-munication from information tapping, and the use of a data link simultaneously for intrusion detecting are also proposed.
