Fiber Optics 100 GBPS

100 GBPS Fiberoptics

Thanks to data-hungry devices such as smartphones, the world now has an almost unquenchable thirst for bandwidth. A new generation of fiberoptic cables promises to meet the need, reaching a threshold of 100 gigabits per second—a significant jump from existing 10- and 40-gigabit-per-second cables, and enough to carry 15,000 HDTV channels simultaneously. Because the new cables encode two bits each in the polarization and phase of a light pulse, rather than a single bit in its intensity, they can pack four times as much data into the signal and reduce the impact of microscopic imperfections in the cables. Alcatel-Lucent has installed a 38-mile test link between two German universities and separately tested its 100 gigabit-per-second Ethernet equipment on Verizon's network in Dallas. The higher-speed cable is now available commercially and will likely carry some of the data you use in the coming year
