Beltelecom WDM network goes 100 Gbps with Huawei

Lightwave Staff

Huawei says it will supply 100-Gbps WDM network technology to Beltelecom of Belarus. The network will cover 1,200 km, with the longest service path connecting Grodno on the Polish border to Vitebsk (on the Russian border).

The Huawei equipment will use ePDM-QPSK coherent 100G technology, Huawei’s version of dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection. The 80-channel WDM systems will have a capacity of up to 8 Tbps.

The network will offer the bandwidth necessary to support a wide variety of data services in Belarus as well as leased-line services, transmitted between Europe and Asia, for Russian carriers.

"Huawei has been our long-time partner and we have witnessed the success of Huawei's 100G trial networks. I am confident that the commercial coherent 100G system will ensure ultra-broad bandwidth with high stability for the national backbone and ultimately help to serve our customers better than ever," said Sergey Sivodedov, chief technical officer of Beltelecom.
