The researchers overcame these issues by fundamentally improving the hollow core design, using an ultra-thin photonic-bandgap rim. This new design enables low loss (3.5 dB/km), wide bandwidth (160nm), and latency that blows the doors off normal optic fiber — light, and thus the data, really is travelling 31% faster down this new hollow fiber. To achieve the transmission rate of 73.7 terabits per second, the researchers used wave division multiplexing (WDM), combined with mode division multiplexing, to transmit three modes of 96 channels of 256Gbps. Mode division multiplexing is a new technology that seems to involve spatial filtering — rotating the signals with a polarizer, so that more of fiber can be used. As far as we’re aware, this is one of the fastest ever transmission rates in the lab. (See: Infinite-capacity wireless vortex beams carry 2.5 terabits per second.)

As for real-world applications, loss of 3.5 dB/km is okay, but it won’t be replacing normal glass fiber any time soon. For short stretches, though, such as in data centers and supercomputer interconnects, these speed-of-light fibers could provide a very significant speed and latency boost.

The core and cladding are usually made of ultra-pure glass, although some fibers are all plastic or a glass core and plastic cladding. The core is designed to have a higher index of refraction, an optical parameter that is a measure of the speed of light in the material, than the cladding, which causes "total internal reflection" to trap light in the core up to a certain angle, which defines the "numerical aperture" of the fiber. More technical details are below.

Glass fiber is coated with a protective plastic covering called the "primary buffer coating" that protects it from moisture and other damage. More protection is provided by the "cable" which has the fibers and strength members inside an outer protective covering called a "jacket".
