Scientists hollow out fiber-optic cables, make data travel at near-light speed

Researchers create fiber network that operates at 99.7 percent speed of light and pushes data rates of 10 terabytes per second.

As it stands now, fiber optic cables provide the fastest broadband Internet to homes. I would know. I flipped out when it increased my regular Internet speeds by 15 times.

Researchers at the University of Southampton in the UK are pushing the possibilities of fiber even farther to the near-ridiculous limits of 99.7 percent of the speed of light. If you think that's fast, wait until you hear that this hollow fiber optic cable can put out data speeds of 10 terabytes per second.

Now that you have a fresh pair of trousers, we can tell you that the UK scientists pulled this off by hollowing out the inside of a regular fiber optic cable and filling it with air.

Scientists already knew that air-filled fiber cables can increase the speed of data transmission via light, but previous attempts have always resulted in data loss whenever the cables had to turn a corner. To fix this issue, the researchers improved the design of their hollow fiber tubes that limits the data loss to an acceptable 3.5 decibels per kilometer.

The researchers say these speeds would never be possible with a regular fiber optic cable because the silica glass causes the light to travel 31 percent slower than the full speed of light in a vacuum (186,282 miles per second speed or 299,792,458 meters per second).

This all sounds great, but we don't expect to see these 10 terabyte per second speeds coming to our homes anytime soon. Most likely, these blistering fiber optic cables will first be used in data centers with racks of supercomputers.
