80×100-Gbit/s transmission over a record 9,000km distance using erbium-doped fiber repeaters only
19 September 2010
: A record transoceanic transmission distance at 100Gbit/s is demonstrated with EDFA repeaters only. The result was obtained with coherent detection, ultra low-loss large effective area fiber, and PDM-QPSK modulation format. ©2010 Optical Society of America OCIS codes: (060.1660) coherent communication; (060.4510) optical communication
