Hauppauge, NY, Spellman High Voltage Electronics Corp, the world’s leading high voltage power supply, X-Ray generator and Monoblock® X-Ray source manufacturer, is pleased to announce that our land-based, PFE Series high voltage power supplies, provided power to the MAREA transatlantic fiber optic cable that recently broke a data transfer speed record. The MAREA cable, owned by Microsoft, Facebook and Telxius, stretches over 4100 miles (6,605 km), from Bilbao, Spain to Virginia Beach, VA.
Researchers at Infinera reported that, during a 16QAM modulation experiment, they reached peak data rates of 26.2 terabytes per second. The theoretical speed was expected to be 20 terabytes per second. At these data rates, and with 8 pairs of optical fibers, close to 5 million HD movies could be streamed at the same time. The MAREA cable normally transmits at 9.5 terabytes per second, still a very high data rate.
Spellman is extremely proud to be part of this technological feat.
