| 摘 要： | 介绍了一款基于并行光纤通信技术的高清视频信号(high-definition multimedia interface, HDMI）传输线缆的研制技术方案。这种新型HDMI线缆采用垂直腔面发射激光器(vertical cavity surface emitting laser, VCSEL）阵列作为发射端，光电探测器（photodiode, PD）阵列作为接收端，两者之间采用多模光纤阵列互连，通过将电信号转变为光信号传输解决了铜缆损耗对电信号传输速率和传输距离的限制。与铜缆HDMI线相比，这种新型HDMI线能够以4信道×3.4Gbps的传输速率实现长达300m的传输距离，为当前高清视频信号和下一代超高清视频信号远距离传输提供了可行的技术方案。

| Abstract: | A 4-channel parallel optical module used for long distance transmission for high-definition multimedia interface (HDMI) signal is implemented and tested. An 850nm vertical cavity surface emitting laser (VCSEL) array is used as the light source of the transmitter, and a photodiode (PD) array is adopted as the detectors of the receiver. Connected by a multimode fiber array with maximum length of 300m, bit rate of each channel is up to 3.4Gbps. While high speed signal can not reach far with traditional copper lines, HDMI fiber is a good solution to meet the needs for long-distance transmission of high definition video signals. |
