Nokia says its Chinese subsidiary Nokia Shanghai Bell (NSB) has been awarded the State Grid Corporation of China (SGCC) optical transport network (OTN) project to support the corporation as it upgrades its Beijing and Tianjin networks from 10 Gbps to beyond 100 Gbps.
SGCC is focusing on supplying power that is economical, safe, and sustainable to improve its production and management process, Nokia affirms. To address the demand for bandwidth capacity and lay the foundation for developing smart grids in the future, an improved OTN supporting integrated data network and operations network services is essential.
At the center of the new SGCC optical network is Nokia's 1830 Photonic Service Switch-32 packet-optical transport systems platform. The 1830 Photonic Service Switch (PSS) family is made up of platforms maximized for optical network deployment environments, including interconnecting data centers, and scaling large long-haul, metro, and regional optical networks (see "Nokia upgrades 1830 PSS packet-optical transport family with new coherent chipsets, improved multi-rate performance"). The platforms each use common software, hardware, management, and control to deliver straight-forward operations throughout.
With 1.72 million employees, SGCC is a state-owned enterprise that operates as a group with RMB 536.3 billion registered capital, Nokia asserts. It builds and operates grids that deliver power to more than 1.1 billion people in 26 provinces, autonomous regions and municipalities, covering 88% of China.
"The new OTN network can provide better technology support for communications, deliver higher level of security and reliability for the power grid, and raise operational efficiency, while improving the business environment to help us deliver better services to our customers," said Zhang Huijian, SGCC Tianjin Electric Information and Communication Corp.'s vice-general manager. "We are pleased to be working with Nokia, which has advanced optical/IP technologies and provides high-quality and professional services to support us in this project."
This project follows the deployment by Nokia Shanghai Bell in Hebei of a comparable optical network serving 100 million SGCC Jibei customers.
Nokia was also chosen by China Mobile Communications Corp. (CMCC) to supply equipment for its regional OTN in April of this year (see "Nokia chosen by China Mobile to supply equipment for regional optical transport network").
