Fiber Optic

GPS has its limitations in urban areas where signals can get noisy. Now, engineers in the Netherlands have developed “SuperGPS” – a hybrid positioning system that combines wireless and optical connections to pinpoint locations within centimeters.
-
Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second.
-
The speed record for data transmission using a single light source and optical chip has been shattered. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), almost twice the global internet traffic per second.
-
Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.
-
Researchers in Japan have clocked a new speed record for data transmission – a blistering 1.02 petabits per second (Pb/s). Better yet, the breakthrough was achieved using optical fiber cables that should be compatible with existing infrastructure.
-
Although fiber optic internet cable has many advantages over metal cable, it frequently has to be distributed underground – this limits its usability. Facebook, however, has developed a robot that could wrap the cable around existing power lines.
-
Although optical fibers are highly effective at data transmission, they're also relatively brittle. An experimental new type of optical fiber addresses that limitation, by incorporating a core made of liquid glycerol.
-
The record for fastest internet speed has been shattered with a data transmission rate of 319 Terabits per second through optical fibers. The record was set over more than 3,000 km of fibers, and is compatible with existing infrastructure.
-
Medical endoscopes may look small, but their tips are actually several millimeters wide, making them too big to image living cells within the body. A new system, however, lets users view images through a single ultra-thin strand of optical fiber.
-
A quantum internet could one day allow quantum computers to team up and tackle some gigantic problems. Researchers at Toshiba are a step closer, demonstrating quantum communications sent over a record-breaking 600 km (373 miles) of optic fiber.
-
Even though underwater remotely operated vehicles (ROVs) are getting smaller, their communications cables have remained relatively fat and hefty. That may about to change, though, thanks to a new fishing-line-based fiber optic tether.
-
Nokia and Vodafone have tested a new broadband technology that delivers a blistering 100 gigabits per second (Gbps). Conducted using the kind of network seen in the last mile between an ISP and a user, it could eventually be rolled out commercially.
