Huawei and Rostelecom Successfully Complete Coherent 100G Trail on Rostelecom’s Live Network

[Shenzhen, China, October 19, 2011]: Huawei, a leading global information and communications technology (ICT) solutions provider, and Rostelecom, the leading fixed network operator in Russia, today jointly announced the successful completion of a coherent 100G trail on a 1,033 kilometer stretch of Rostelecom’s live network between the cities of Moscow and Samara.

Coherent 100G is the latest technology for transmitting high-speed 100G services, making them better adapted to fiber transmission so that services can be transmitted at a higher rate over a longer distance.

The rapid growth of bandwidth leasing has led to an explosive increase in broadband services transmitted between Europe and Asia. This traffic accounts for most of the transport capacity of Rostelecom’s backbone networks, and to ensure that it can continue to develop services in the future, Rostelecom has been exploring the possibility of constructing 100G backbone transport networks. This trial confirmed the possibility of using coherent 100G technology on Rostelecom’s live network.

The link between Moscow and Samara, an important industrial city in the Volga region, is one of Rostelecom’s busiest, and is therefore in urgent need of 100G technology. Huawei’s 100G technology, which uses ePDM-QPSK (enhanced Polarization Division Multiplexing Quadrature Phase Shift Keying), is the most advanced technology in the 100G transport network field. It is able to perform well in both anti-nonlinearity and ultra-long haul transmission, which made it perfectly equipped for this coherent 100G trail.

During the trail, Huawei’s 100G technology allowed 100GE services to be successfully transmitted over the 1,033 kilometers between Moscow and Samara without the use of an electrical regenerator. In addition, hybrid transmissions of 100G and 40G services were achieved.

“In 2002, Huawei deployed the first Wavelength Division Multiplexing backbone network for Rostelecom, and since then, Huawei’s WDM products have been deployed on 25,000 kilometers of Rostelecom’s backbone network,” said Evgeny Zhukov, head of technical solutions to regional transportation networks of Huawei in CIS. In addition to spurring the evolution of transport technologies from 10G to 40G and then to 100G, Huawei has also kept forging ahead in the development of WDM networks to provide customers with more valuable solutions and services.

“We are happy that our coherent 100G solution passed Rostelecom’s rigorous testing with flying colors. The experience gained during the test will be very helpful in deploying 100G services in the future.”

As an industry-leading transport vendor, Huawei is committed to providing operators worldwide with premium WDM/OTN, MSTP/Hybrid MSTP, and microwave products in addition to end-to-end transport solutions. According to consulting firm Ovum, Huawei leads the global optical network market, the WDM/OTN market, and the 40G market as of the second quarter of 2011.
