WUHAN -- Chinese firm FiberHome has developed a type of optic fiber that can transmit 400 terabytes of data per second, breaking the world record for the amount of data that can be transmitted on optic fibers, the company said earlier this week.

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 provincial capital of central China's Hubei Province.

The transmission of 400 terabytes of data is accomplished 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.

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