Huawei and China Southern Power Grid jointly released the "Smart Grid Next Generation Bearer Technology Liquid OTN White Paper"

In the F5G era, Liquid OTN is the next-generation optical bearer technology. It inherits the high security features of traditional SDH hard pipes while being innovative for the future. It provides better low-latency performance through protocol simplification and reduces equipment latency by 30%. It uses innovative fusion technology to create a minimalist network architecture, saving 30% of the TCO of the entire network.

As an important national basic industry, smart grid also combines tradition and innovation. Safety is the highest priority requirement in any era. As a relay protection service that requires real-time control, it requires 99.999% reliability and strict latency requirements of less than 5ms. With the development of smart grids, intelligent perception of equipment and cloud-based applications have triggered an exponential growth in grid data. The device interface rate ranges from 4Mbps to 100Mbps. It is estimated that by 2025, the daily increase in data collected by the entire network will exceed 100TB. At the same time, a large number of centralized and distributed new energy power generation projects are connected to the grid, the network layers are increasing simultaneously, and network operation and maintenance management is becoming increasingly complex.

The white paper released this time introduces the next-generation optical bearer technology Liquid OTN in detail, pointing out that this new technology is the choice for the next-generation power production bearer network in the face of the needs and challenges brought by the development of smart grids, with its highly competitive high security, deterministic low latency, and simple architecture. It provides physical isolation and protection against multiple fiber breaks for key businesses of power production and scheduling, ensuring absolute security and stability; based on a converged platform, it meets the diverse needs of both traditional small-granularity businesses and future rapidly growing large-data volume businesses; simplifies the bearer network layer and reduces operation and maintenance costs.

The State Grid Corporation of China believes that the development direction of Liquid OTN is in line with the needs of power communications, and also calls on all walks of life in private network communications to jointly promote the relevant standardization process.

Hong Danke, Director of the Communications Department of China Southern Power Grid, pointed out: "Power production communications have entered a challenging period. We firmly believe that F5G all-optical networks represent a new era and new opportunities, so we chose to work closely with Huawei to jointly achieve innovative development in the power industry. The two parties will conduct joint tests on Liquid OTN in various scenarios such as relay protection and production dispatching networks, incubate more innovative application results, and help China's power industry transform into an intelligent one."

Jin Zhiguo, President of Huawei Enterprise Transmission and Access Domain, delivered a keynote speech entitled "In the F5G era, Liquid OTN ensures safe production" at the conference: "In the F5G era, Liquid OTN, as the next-generation optical transmission technology, has given new meaning to optical bearer networks. Relying on key innovations such as 'hard pipes, protocol simplification, and technology integration', it provides digital power with a high-quality experience of 'high security, low latency, and simple architecture', ensuring safe production. As a leader in the optical industry, Huawei will continue to increase R&D investment to help customers build leading and sustainably evolving all-optical networks, and help accelerate transformation in all industries."

The release of the white paper is an important initiative by China Southern Power Grid and Huawei for the power industry, and has important guiding significance for promoting the integration and innovation of the power industry and next-generation optical transmission technology.
