34.5 m Underwater optical wireless communication with 2.70 Gbps data rate based on a green laser with NRZ-OOK modulation

This study proposed and experimentally demonstrated a high-speed long-distance underwater optical wireless communication (UOWC) system using a 520 nm green laser diode (LD) with non-return-to-zero on-off keying (NRZ-OOK) modulation scheme. The UOWC link offers maximum data rates up to 4.60 Gbps, 3.93 Gbps, 3.48 Gbps and 2.70 Gbps over the underwater distances of 2.3 m, 11.5 m, 20.7 m and 34.5 m with the bit-error rates below the forward error correction (FEC) criterion of 3.8 χ 10−3. To the best of our knowledge, UOWC data rate of 2.70 Gbps at 34.5 m is the highest at present.
