Scientists at Karlsruhe Institute of Technology (KIT) have succeeded in encoding data at a rate of 26 terabits per second on a single laser beam, transmitting the data over a distance of 50 kilometers, and decoding the information successfully. This is the largest data volume ever transported on a laser beam. The process developed by KIT enables the transmission of 700 DVDs' worth of content in just one second. The advance is reported in the journal Nature Photonics. In this experiment, KIT scientists led by Professor Jürg Leuthold beat their own record in high-speed data transmission of 2010, when they...

The first IP router on a commercial satellite has successfully passed its in-orbit test, moving the military and commercial customers closer to an era of faster satellite communications. The Internet Routing in Space (IRIS) technology is expected to reduce latency and increase efficiency, said Steven Boutelle, vice president of Cisco Global Government Solutions Group. Boutelle, who served as the U.S. Army’s chief information officer prior to joining Cisco, said IRIS can route data to multiple ground receivers in a single step, eliminating the need to double-hop to a teleport, reducing latency and increasing transponder utilization. The router and modem software...
