提出了一种利用漏塑料光纤作为漏馈光纤的水下无线光通信新概念,并进行了实验验证。泄漏的POF可以潜在地改善UWOC覆盖。正交频分复用(OFDM)的演示,以提高频谱效率和鲁棒性的泄漏塑料光纤与大的核心模式色散。采用16正交幅度调制(QAM)-OFDM调制,在沿10 m泄漏POF馈线沿着的两个离散辐射点处实现了224.61 Mb/s的比特率(净比特率:183.69 Mb/s)。在30 cm水下信道上,两点的平均误码率分别为3.37×10− 5和3.35×10−3,低于前向纠错门限3.8×10−3。
A novel concept of using a leaky plastic optical fiber (POF) as the leaky feeder for underwater wireless optical communication (UWOC) is proposed and experimentally demonstrated. The leaky POF can potentially improve the UWOC coverage. Orthogonal frequency division multiplexing (OFDM) is employed in the demonstration to increase spectral efficiency and robustness to modal dispersion of the leaky POF with a large core. A bit rate of 224.61 Mb/s (net bit rate: 183.69 Mb/s) at the two discrete radiation points along a 10-m leaky POF feeder is achieved using 16-quadrature amplitude modulation (QAM)–OFDM modulation. Over a 30-cm underwater channel, the mean bit errors (BERs) measured at the two points are 3.37×10−5and 3.35×10−3, respectively, which are below the FEC threshold of 3.8×10−3.
