Huawei and Beltelecom Successfully Test 100G Coherent Transmission on Beltelecom’s Live Network

[Shenzhen, China, November 09, 2011]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced that it successfully tested the first 100G coherent transmission on the live network of Beltelecom, a national telecommunications operator of the Republic of Belarus.

The trial was performed on a link in the Beltelecom backbone WDM (wavelength-division multiplexing) network that connects Russia and Poland and travels across Belarus. During the trial, 100G services were transmitted together with existing 10G and 40G services over the same fiber, while achieving non-regeneration transmission over a distance of 900 kilometers.

Beltelecom had been facing several challenges in meeting the increasing demands for FTTx (Fiber to the x) bandwidth access services and international bandwidth leasing services. Although ample 10G and 40G services had been deployed on the network using Huawei’s OTN (Optical Transport Network) devices, the heavy demand on Beltelecom’s network necessitated 100G ultra-high speed transmissions in order to quickly and effectively expand the network’s capacity. To meet this need, Huawei and Beltelecom deployed this 100G coherent transmission test on Beltelecom’s WDM network.

During the testing process, Huawei used the ePDM-QPSK (enhanced Polarization Division Multiplexing Quadrature Phase-Shift Keying) modulation technique, which is recognized as the single best modulation technique for 100G long-haul transmission. Without making any changes to the live Beltelecom network, Huawei successfully achieved transmissions of 10G, 40G, and 100G services over the same fiber, enabling every wavelength in the network to carry 100G services without adversely affecting existing 10G and 40G services. This achievement will help Beltelcom further leverage the investment it has already made in its current network.

Sergey Sivodedov, chief technical officer of Beltelecom, said, “Collaborating with Huawei in testing 100G coherent transmission has successfully demonstrated that the 100G transmission system is mature and ready for commercial applications. This solution will help us accelerate the building of ultra-broadband networks so that we can provide users with a wider range of services.”

Xu Zhidong, CEO of Huawei Belarus, said, “Huawei is committed to the continuous improvement of its technical innovations and its customer-oriented solutions and services. Last year, Huawei successfully upgraded the service rate of Beltelecom’s live network from 10G to 40G, and this most recent 100G coherent transmission test further demonstrates Huawei’s ongoing commitment to providing the most advanced technologies so that operators can expand their networks and create value. This accomplishment again shows that Huawei is a trusted partner for operators.”

As an industry-leading transport provider, Huawei is committed to providing operators worldwide with premium end-to-end WDM and OTN transport solutions. In 2007, Huawei’s OTN-based large capacity, full service solution was awarded an InfoVision Award from the International Engineering Consortium (IEC) in recognition of its contribution to the evolution of the WDM industry.

According to the most recent information available from Ovum, a leading market research firm, Huawei currently leads the global optical network market, the WDM/OTN market, and the 40G market.
