China Mobile, Huawei Announce Enterprise Private Line on NG OTN

China Mobile Guangdong and Huawei have jointly announced the launch of the world's first enterprise private line service based on Next-Generation Optical Transport Network (NG OTN) technology between Guangzhou’s Dongfengzhong and Liwan districts.

Launch of the service marks a significant upgrade of China Mobile Guangdong's smart private network, which will fully adapt to the differentiated private line connection requirements of enterprises of all sizes, accelerate the digital transformation of vertical industries, and lay a solid foundation for a booming digital economy in Guangdong Province.

New infrastructure construction represented by 5G and all-optical networks will be increasingly crucial in supporting high-quality economic development. In 2018, China Mobile Guangdong established an all-optical smart city group in the Greater Bay Area (covering Guangdong, Hong Kong, and Macao) and built an all-optical network in the region centering on Guangdong's major cities: Guangzhou, Shenzhen, Dongguan, and Foshan.

In 2019, China Mobile Guangdong built a smart private network covering the entire province, enhancing capabilities of virtual channel grooming based on the Greater Bay Area’s all optical network and providing premium private line services for industries such as finance and healthcare as well as government.

To further utilize the potential of the new all-optical infrastructure network, China Mobile Guangdong will continue to innovate in 2020 to promote application of smart private networks in additional industries and enterprises, supporting the rapid development of Guangdong's digital economy.

China Mobile Guangdong and Huawei’s joint innovation in NG OTN technology defines a smaller-granularity and more flexible optical network that supports an expanded number of service connections, higher resource utilization, and lower transmission latency, further enhancing the capability of smart private networks.

• Minimum service granularity is 2 Mbit/s, and the number of network connections is increased 100 times. 100G can support 1000 service connections, providing massive premium private line services for industries.
• Reducing processing latency of devices by up to 90% assures ultra-low latency for financial and industrial manufacturing scenarios.
• 2 Mbit/s to 100 Gbit/s stepless speed and hitless adjustment provides bandwidth on demand (BOD) without interrupting services.
• The integrated all-optical network is compatible with multiple technologies such as SDH, OTN, and NG OTN, supports flexible access of enterprise customers anywhere in the province, and ensures fast service provisioning within days.

Cai Weiwen, Deputy General Manager of China Mobile Guangdong, said, "China Mobile Guangdong insists on driving business development through technological innovation, enabling digitalization of the industry, and helping make breakthroughs for industry groups. In our collaboration with Huawei, smart private networks powered by NG OTN can provide more enterprise customers with high-quality private line services that are secure, convenient, and simplified, effectively supporting the innovation and development of vertical industries, and facilitating digital transformation in the Greater Bay Area."

Simon Lu, President of Huawei's Transport Network Domain, said, "The joint innovation of Huawei and China Mobile Guangdong in development of NG OTN is another milestone in our collaboration. As a next-generation optical transport technology, NG OTN will accelerate popularization of all-optical networks, provide a high-quality experience for various industries, promote success of the optical industry, and enable collaborative development of industry and business innovation."

In line with the strategic aim of the all-optical smart city group, China Mobile Guangdong has deployed Optical Cross-Connect (OXC) devices at more than 40 transmission nodes. The cloud-based OTN intelligent management and control system has managed over 55,000 NEs, facilitating China Mobile Guangdong's construction of a world-leading all-optical network.

The provisioning of NG OTN-based government and enterprise private line service will accelerate the penetration and convergence of all-optical networks as well as various fields and industries, paving the way for a new digital infrastructure in the Greater Bay Area. In the future, China Mobile Guangdong and Huawei will continue to explore innovations in the all-optical field, jointly promote construction of an all-optical smart city group, and drive technological innovation and industry upgrades.
