实验研究了一种基于开关键控非归零码（OOK-NRZ）调制的水下高速无线光通信（UWOC）。通信链路使用商业TO-9封装的尾纤520 nm激光二极管（LD）作为光发射器，带宽为1.2 GHz，雪崩光电二极管（APD）模块作为接收器。在2.3 Gbit/s传输时，接收数据的测量误码率为2.23x10（-4），远低于无差错操作所需的前向纠错（FEC）阈值2x 10（-3）。高带宽的LD加上高灵敏度APD和优化的工作条件是在我们提出的系统中获得高比特率传输的关键使能因素。据我们所知，这一结果是迄今为止UWOC系统中达到的最高数据速率。(C)2015美国光学学会
We experimentally demonstrate a record high-speed underwater wireless optical communication (UWOC) over 7 m distance using on-off keying non-return-to-zero (OOK-NRZ) modulation scheme. The communication link uses a commercial TO-9 packaged pigtailed 520 nm laser diode (LD) with 1.2 GHz bandwidth as the optical transmitter and an avalanche photodiode (APD) module as the receiver. At 2.3 Gbit/s transmission, the measured bit error rate of the received data is 2.23x10(-4), well below the forward error correction (FEC) threshold of 2x10(-3) required for error-free operation. The high bandwidth of the LD coupled with high sensitivity APD and optimized operating conditions is the key enabling factor in obtaining high bit rate transmission in our proposed system. To the best of our knowledge, this result presents the highest data rate ever achieved in UWOC systems thus far. (C) 2015 Optical Society of America
