Huawei announced that, KPN International introduced the based on second generation of soft decision 100G WDM technology from Huawei. 100G signals transmitted from the existing network of Amsterdam to Paris, via Germany, transmission distance up to 1,400 km. Because the system has a great margin, and later at the end of the site added 300 km fiber, the signal is still being successfully transmitted. The successful launch marks the 100G technology entered into a new commercial era.
Soft-decision is the most leading optical signal powerful error correction technology, is the key of 100G technology to large-scale commercial. And the second generation of soft decision adopts oDSP module, developed for Huawei’s 400G technology, in essence is with 400G technology to enhance the performance of 100G, realizes the further optimization of the FEC algorithm, achieve a lower damage in transmission performance, lower single-bit power consumption. Benefit from the breakthroughs in key technologies, compare to the first generation of soft-decision system, the second generation soft decision improves the transmission distance from 3000 km to 4000 km, the transmission performance is improved by 30%.
KPN International introduced the second generation of soft decision technology sucessfully, fully demonstrated the new generation 100G technology has matured, and also verified the Huawei 400G core modules maturity. KPN International began using Huawei next WDM system in pan-European wavelength division trunk in 2008, the network is one of Europe’s largest and most leading WDM networks, KPN International was the first to deploy Huawei coherent 100G WDM technology in 2011.
“Customer success is the constant pursuit of Huawei,” Huawei Transport Network Product Line CEO Wang Weibin said, “Huawei has long-term cooperation with leading operators such as KPN , to meet the needs of customers, and work with customers to open a window to the future.”
Huawei is the best partner for next-generation WDM network customers, so far, has builded over 90 100G commercial network. According to industry authority consulting company Ovum statistics, as the first quarter of 2013, Huawei continues to rank first in the global optical network market, ranks first in the global WDM/OTN market, ranks first in the global 100G and 40G market.
