Facebook built a new fiber-spinning robot to make internet service cheaper

Facebook has designed a robot that can install fiber on traditional power lines, as shown in this rendering.

 The robot’s code name is Bombyx, which is Latin for silkworm, and pilot tests with the machine begin next year.

The robot rests delicately atop a power line, balanced high above the ground, almost as if it’s floating. Like a short, stocky tightrope walker, it gradually makes its way forward, leaving a string of cable in its wake. When it comes to a pole, it gracefully elevates its body to pass the roadblock and keep chugging along.

This isn’t a circus robot. Facebook developed the machine to install fiber cables on medium-voltage power lines around the globe. The aim is to make it cheaper for internet service providers to build out their networks using super-fast and reliable fiber connections. Installing fiber is a pricey endeavor, limiting where it can be deployed. If the cost of installation goes down, says Facebook, so too does the cost of service for the end user.

‘Twisted’ fibre optic light breakthrough could make internet 100 times faster

A new development in fibre optics could make internet speeds up to 100 times faster – by detecting light that has been twisted into a spiral.

The research, published in the journal Nature Communications, can be used to easily upgrade existing networks and significantly boost efficiency, scientists say.

Fibre optic cables use pulses of light to transmit information, but currently information can only be stored through the colour of the light, and whether the wave is horizontal or vertical.

By twisting light into a spiral, engineers effectively create a third dimension for light to carry information: the level of orbital angular momentum, or spin. “It’s like DNA, if you look at the double helix spiral,” said Min Gu from RMIT University. “The more you can use angular momentum the more information you can carry.”
