[Moscow, Russia, October 27, 2011]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced that it had sequentially collaborated with top Russian operators such as Transtelecom, Rostelecom, Vimpelcom, and Megafon in testing and demonstration of the 2000 km ultra-long haul (ULH) 100G coherent WDM (Wavelength Division Multiplexing) system at Huawei’s 100G testing center in Russia. This announcement marks the beginning of Russia’s commercial applications of 100G WDM transport networks. The stability of the 100G ULH coherent WDM system has fully demonstrated the maturity and state-of-the-art attributes of Huawei’s 100G transport solution.
Coherent 100G technology, with a maximum line rate of 100 Gbit/s, is considered the most up-to-date technology that is able to deliver superior performance in mitigating chromatic dispersion and polarization mode dispersion. Using this technology, 100 Gbit/s signals are more adaptable to fiber transmission while yielding a remarkable increase in bandwidth capacity for WDM systems. As such, the bandwidth capacity can reach as high as 8 Tbit/s over a single fiber and the regeneration-free transmission distance is significantly extended.
Russia is vast and has been in constant need of a solution that can transmit high-speed signals over ultra-long spans. Transtelecom, for example, owns the world’s longest WDM backbone that is 18713 km long. Through collaboration with Huawei, Transtelecom created several new records in WDM transmission distances for its WDM commercial applications. Such breakthroughs included regeneration-free transmission of 10 Gbit/s signals over a distance of 2500 km during the 10G era and 40 Gbit/s signals over a distance of 1200 km during the 40G era. As coherent 100G technology is maturing, top operators in Russia have continued to collaborate with Huawei and are primed to pave the way for 100G commercial applications.
The testing fully demonstrated the superior service performance and stability of Huawei’s 100G coherent systems. Huawei was able to show that its solution could transmit 100 Gbit/s services in combination with existing 10 Gbit/s and 40 Gbit/s services over a regeneration-free transmission distance of more than 2000 km.
Sergey Varyukhin, regional vice president of Huawei in Russia, Ukraine and Belarus, said, “As the largest and best partner of Russian operators in the 10G and 40G WDM transport field, Huawei continues to deliver industry-leading 100G solutions that help customers in Russia smoothly upgrade their networks into the 100G era. Huawei will sustainably help customers build the most advanced high-speed transport networks.”
As an industry-leading transport vendor, Huawei is committed to providing operators worldwide with premium WDM/OTN, MSTP/Hybrid MSTP, and microwave products as well as end-to-end transport solutions. Huawei led the global optical network market, WDM/OTN market, as well as the 40G market according to information released during the fourth quarter of 2010 by Ovum, a well-known consulting firm in the telecom industry.
