Chinese firm FiberHome has developed a type of optic fiber¹ that can transmit 400 terabytes of data per second, breaking the world record for the amount of data that can be transmitted on optic fibers², the company said.

中国公司烽火通信近日表示，该公司研发出一种每秒可以传输400兆兆字节(T)数据的光纤，打破了光纤传输数据量的世界纪录。

Such capacity would allow for simultaneous phone calls by 4.8 billion people and the transmission of 40,000 blue-ray high definition movies (10 gigabytes per movie) in one second, according to the company based in Wuhan, the provincial³ capital of central China's Hubei province.

这家总部位于中国湖北省首府武汉市的公司表示，这样的传输能力可以让48亿人同时通话，1秒钟内可传输4万部蓝光高清电影，每部电影的数据大小为10千兆字节。

The transmission of 400 terabytes of data is accomplished⁴ on multi-core mono-mode optic fiber, which can be simply understood as breaking down the fiber into multiple paths to enhance transmission capacity, according to technicians.

技术人员称，完成400T数据的传输要基于多芯单模光纤，后者可简单理解为在一根光纤中开辟了多条并行道路，从而提升传输能力。

Such expansion in transmission capacity is a welcoming development amid growing demand for high speed transmission of data for virtual reality, the Internet of Things, cloud computing⁵ and other emerging technologies.

随着虚拟现实、物联网、云计算及其他新兴技术对高速传输数据的需求不断增加，此类传输能力的提升是一项大受欢迎的研发成果。
