Classification: CPC H | IPC H

Claim 8:
9. An optical data transmission method performed by the data transmission system according to claim 1, comprising:
modulating the first audio signal to be transmitted to a swimmer and transmitting the first audio signal to the at least one light source,
converting the first electrical signal received from the at least one light source into the optical signal,
propagating the optical signals transmitted from the at least one light source through water and transmitting the optical signals to the at least one light sensor of the swimmer,
collecting aggregated optical signals by the at least one light sensor and converting the aggregated optical signals into the second electrical signal,
demodulating the second electrical signal received from the at least one light sensor to retrieve the data signal,
converting the data signal into the second audio signal, and
playing the second audio signal by an output unit.
