Researchers push 44.2Tbps through existing optic fiber cables

Australian researchers figured out a way to achieve a bandwidth of 44.2Tbps using existing fiber optic lines. The technique uses an optical device called a microcomb, it replaces the roughly 80 lasers found in modern telecom equipment. The main implication here is that cables that are currently in the ground still have a bright future:
The team -- which consists of researchers from Monash, Swinburne and RMIT universities -- achieved such a fast connection by using an optical device called a microcomb to replace the standard bunch of about 80 lasers found in modern telecom equipment. According Phys.org, a microcomb “generates very sharp and equidistant frequency lines in a tiny microphotonic chip.” This specialized technology is compatible with existing fiber optic lines, which hopefully means that the internet’s pipelines don’t need to be overhauled in order to reach such fast speeds. "What our research demonstrates is the ability for fibers that we already have in the ground...to be the backbone of communications networks now and in the future,” said Bill Corcoran of Monash University.
