Huawei has collaborated with Transtelecom, Rostelecom, Vimpelcom, and Megafon in testing and demonstration of a 2000 km ultra-long haul (ULH) 100G coherent WDM (Wavelength Division Multiplexing) system at Huawei’s 100G testing center in Russia. Huawei was able to show that its solution could transmit 100 Gbps services in combination with existing 10 Gbit/s and 40 Gbit/s services over a regeneration-free transmission distance of more than 2000 km.
Huawei said its 100G ULH coherent WDM system is now fully mature and ready for deployment.
