Huawei and Rostelecom complete coherent 100G trail on Rostelecom’s network


Huawei and Rostelecom, a fixed network operator in Russia, jointly
announced the 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 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, 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.

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.
