Huawei makes stamp on 100G trend with Beltelecom network win

Beltelecom, the Belarusian state-owned fixed line and broadband operator, has employed Huawei to build out its 100G optical network.

The 1,200 km WDM-based network, which leverages the vendor's optical coherent detection technology, will transit Belarus via a link from Grodno on the Polish border to Vitebsk near the Russian border.

This deployment follows a 100G transmission trial that Beltelecom conducted with Huawei on its live national backbone network over the Grodno-Vitebsk route. Over a distance of 900 km, the trial tested the ability to concurrently transmit 10G and 40G services over the same fiber without regeneration.

For the live 100G long-haul network transmission test, Huawei leveraged Polarization Division Multiplexing Quadrature Phase-Shift Keying (ePDM-QPSK) modulation. Beltelecom will leverage the same ePDM-QPSK modulation format when the network is commercially launched to provide up to 8 Tbps of capacity.

Given all of the customer announcements for 100G by Huawei's key competitors--Alcatel-Lucent (NYSE: ALU) and Ciena (Nasdaq: CIEN)--lately, the win will Beltelecom gives the Chinese vendor its own proof point that its 100G systems are up to serve the task in large networks.

Overall, the ongoing deployments by Beltelecom reflects the larger trend where 40G and 100G deployments are driving 19 percent growth in the DWDM market as seen in a recent Dell'Oro report. Led by the trio of Huawei, Ciena and Alcatel-Lucent the 40G and 100G wavelength market grew over 60 percent, contributing almost one-third of the DWDM equipment segment's revenues in 2011.
