根据发表在《自然光学》上的研究报告，美国贝尔实验室的研究人员发现，耳机主动式降噪技术可用于提高光纤连接的速度和可靠性。降噪耳机接收外界的噪音，然后通过耳机内部的电子电路产生与噪音音波相位相反的信号，以此来消除外界噪音。研究人员认为，他们可以在光缆上做同样的事情，只是用光信号取代电信号。领导这项研究的Xiang Liu称他们的光缆降噪技术为相位共轭，使用这项技术能通过12800公里长的光缆发送400Gbps的信号，400倍于Google光纤服务。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
