Acoustic Communication refers to the use of sound waves to transmit information through an optical fiber. Fiber-optic sensors are devices that utilize the principles of fiber optics to detect and measure physical parameters such as temperature, pressure, strain, or acoustic signals. Acoustic communication involves employing the optical fiber as a medium to transmit and receive acoustic signals for sensing applications.


Distributed Fiber-Optic Sensor as an Acoustic Communication Receiver Array

A novel acoustic transmission technique using distributed acoustic sensors is introduced. By choosing better incident angles for smaller fading and employing an 8- channel beamformer, over 10KB data is transmitted at a 6.4kbps data rate.

OFDM Signal Transmission Using Distributed Fiber-Optic Acoustic Sensing

Acoustic data transmission with the Orthogonal Frequency Division Multiplexing (OFDM) signal has been demonstrated using a Distributed Acoustic Sensor (DAS) based on Phase-sensitive Optical Time-Domain Reflectometry (?-OTDR).
