SHENZHEN, China -- 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 trial on a 1,033 kilometre 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 trial.
