KEPCO Develops 80Gbps/wave Optical Communications Technology.Tokyo, Japan, Nov 2, 2005 - (JCNN JCNN Japan Corporate News Network ) - Kansai Electric Power (KEPCO KEPCO Korea Electric Power Corporation KEPCO Kansai Electric Power Company, Inc. (Japan) KEPCO Kyushu Electric Power Company, Inc. (Japan) ) has successfully transmitted optical signals at 80Gbps on 16 waves, an equivalent of 1.28Tbps, over a distance of 116km via optical ground wires (OPGWs), a long optical fiber network that is owned by a power company. The KEPCO technologies that have been newly developed in association with the experiment include variable dispersion dispersion, in chemistry dispersion, in chemistry, mixture in which fine particles of one substance are scattered throughout another substance. A dispersion is classed as a suspension, colloid, or solution. control, a system to enable real-time detection for the fiber's dispersion caused by different weather conditions, especially temperature, so it can reduce deteriorations in signal waveforms to achieve stable data transmissions. Also employed is an optical signal amplification technology based on dispersion compensation fibers, which are used for high-speed communication paths, preventing optical signal attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. from occurring for a transmission distance of 60km or longer. Through further tests, KEPCO aims to make these technologies feasible for commercial use in trunk line communications between large cities.
