Abstract
Abstract This paper has demonstrated an experimental low power consumption underwater wireless optical communication (UWOC) system with 460-nm LZ1-00DB00 Blue LED and avalanche photodetector. With the LZ1-00DB00 Blue LED operating at a driving current of 1200 mA with an optical power of 5280 mW, UWOC link offering a data rate up to 20 Mb/s over a transmission range of 5 meters under an underwater channel link. The measured bit-error rate (BER) is 3 × 10 - 3 which pass well the forward error correction (FEC) threshold.
