Huawei tapped for China's first coherent 100-Gbps OTN infrastructure

Huawei says that Gansu Administration of Radio, Film and Television has selected the systems provider to deploy the country’s first network that will combine 100-Gbps coherent technology with Optical Transport Network (OTN) capabilities.

The administration, which oversees radio, film, and television production and provision in Gansu province, will use the Huawei technology to upgrade its current SDH-based provincial backbone fiber-optic network to better support such services as video on demand, high-definition video, and broadband. The administration expects the new network’s use of coherent 100G technology, OTN, and an automatically switched optical network (ASON) architecture, will meet its requirements for the next five years. The network deployment will comply with the specifications of the Next Generation Broadcasting (NGB) project of the State Administration of Radio, Film, and Television (SARFT), Huawei adds (see "China mandates consolidation in cable system operators market").

Huawei says the systems on the new infrastructure will support 8 Tbps per fiber while supporting a mix of 10G/40G/100G wavelengths. The intelligent ASON control plane will support resilient protection against multiple fiber cuts and guarantee high network reliability, the company adds. The control plane also will support a variety of service classes.
