China Telecom chooses Huawei for global backbone OTN deployments

It may have lost out to ZTE at China Mobile (see “ZTE trumpets China Mobile 100-Gbps OTN awards”), but Huawei has found more than adequate compensation at China Telecom. The Chinese systems vendor says it will supply its Optical Transport Network (OTN) and WDM fiber-optic network technology for an upgrade of China Telecom’s international SDH network.

It may have lost out to ZTE at China Mobile (see “ZTE trumpets China Mobile 100-Gbps OTN awards”), but Huawei has found more than adequate compensation at China Telecom. The Chinese systems vendor says it will supply its Optical Transport Network (OTN) and WDM fiber-optic network technology for an upgrade of China Telecom’s international SDH network.

China Telecom expects the upgrade from SDH to OTN will improve its ability to provide high-bandwidth international private line services. SDH’s access, switching, line capacities, and scheduling capabilities have become inadequate to accommodate the rapid expansion of the carrier’s private line services, Huawei says. Moving to OTN will provide China Telecom with greater access capacities and more flexible scheduling.

The backbone upgrades will cover networks in the U.S., UK, Sweden, Germany, Singapore, Hong Kong, and eight provinces of mainland China. The deployment will include multiple core nodes in these regions, Huawei says. The networks will connect to various carrier networks around the world and expand with the development of services.

Huawei says it won the awards based on its ability to demonstrate to deliver high-capacity OTN technology, a global supply and delivery system, “mature applications” and experience, and long-term network evolution capability.
