Rostelecom, the leading fixed network operator in Russia, has completed a coherent 100G trail on a 1,033 kilometer stretch of it’s live network between the cities of Moscow and Samara using Huawei’s platform. This route is one of the busiest in Rostelcom’s network.
Huawei’s 100G uses ePDM-QPSK (enhanced Polarization Division Multiplexing Quadrature Phase Shift Keying) and is able to perform well in both anti-nonlinearity and ultra-long haul transmission. Huawei said the trial successfully carried hybrid transmissions of 100G and 40G services without the use of an electrical regenerator. http://www.huawei.com
