Huawei this week won a deal to provide 400G core network routers to Russian operator MegaFon as it upgrades its IP backbone to cope with increasing mobile data demand.
"Traffic growth brings great pressure to the network," said Zha Jun, president of Huawei's fixed network business, at Broadband World Forum on Wednesday. "If we take 100 minutes of HD TV, that's equal to the voice traffic of the last 10 years."
Just two Huawei routers "provide the equivalent capacity of 10 of MegaFon's existing core routers," he claimed.
As well as offering a significant capacity upgrade, he said Huawei's NE5000E 400G core router also consumes one eighth the amount of power and takes up one sixth the amount of floor space compared to the current crop of 100G routers.
"It lowers the opex of carriers," Zha said.
Wednesday's deal brings the total number of 400G router contracts secured by Huawei to 20. The Chinese vendor is aiming to increase that figure to 50 by the end of 2013.
As well as MegaFon, Huawei's 400G customers include Etisalat's Saudi unit Mobily, and Thai mobile operators True and DTAC.
Zha said the 400G customers it has signed up are based in the Middle East, Africa, Russia and Asia-Pacific.
"In Europe, progress is slower," he admitted, although he expects it to pick up the pace going forward.
