Huawei Releases All-Optical Power Communication Network White Paper, Accelerating Power Digital Transformation

DUBAIWATER, October 14, 2022 /PRNewswire/ — During HUAWEI CONNECT 2022 in Dubai, Huawei Global Electric Power Summit themed “Unleash Digital and Create New Value for Electric Power”, Huawei released the White Paper on All-Optical Power Communication Network Architecture and Technologies to facilitate the digital transformation of the electric power industry.

Jason Li, Director of Marketing and Solution Sales, Electric Power Digitization Business Unit of Huawei, delivered a speech in which he pointed out that the electric communication network is the basis for the automatic distribution of the electric network, operations market-oriented network systems and modernized management. He also noted that such a network is an important means to ensure safe, stable and economical operations of the power grid as well as the basic infrastructure of the power system. The white paper, published by Huawei, describes how to build an intelligent optical foundation for power communication networks based on the all-optical architecture. It also aims to help the electric power industry face digital challenges, meet the technical requirements of digital transformation, and accelerate digital transformation.

The digital transformation of the electric power industry requires that the electric communication network inherits the rigid pipe technology used on the production network services – such as SCADA, security and stability system and teleprotection – to ensure high reliability and deterministic low latency of the production network. In addition, the electrical communication network must also be capable of carrying future-oriented services, such as situational awareness and IoT, to improve network bandwidth scalability and flexibility. multi-service support. With the development of the fifth-generation fixed network (F5G), the optical service unit (OSU), as a fifth-generation native hard pipe (NHP) technology, makes the best use of SDH and OTN technologies. It supports ultra-high bandwidth beyond 100G and provides service access capabilities from 2Mbps to 100Gbps, meeting the needs of production network services and utility-oriented services. ‘coming. These strengths make OSU the preferred solution for building digital power grids and upgrading SDH networks.

According to the white paper, OSU technology is integrated into the backbone network, power transmission and transformation network, and power distribution/substation network to implement highly secure support of network services at every layer. The architecture implements single-hop E2E transmission from the substation/power distribution network to the backbone network, making the NHP all-optical architecture the optimal power communication network architecture. Specifically, the NHP all-optical architecture of the power communication network has the following characteristics:

  • The NHP all-optical architecture provides high network compatibility, service isolation, and wide site coverage. It allows networks in each layer to inherit the original rigid pipe technology and ensures smooth evolution of service systems.
  • OSU technology implements single-hop transmission of E2E services, providing secure isolation between service systems. In addition, uniform management interfaces and technical standards are provided to simplify management and operation and maintenance.
  • OSU over Passive Optical Network (OSU over PON for short) implements hard-driving PON, extending NHP to scenarios such as substations. E2E hard channels and hard isolation not only implement E2E service provisioning, but also ensure service security and quality.
  • In terms of security, NHP all-optical communication network systems are physically isolated from each other. Based on the zero-trust framework, a defense-in-depth system is designed for the electrical communication network to meet the availability, reliability, and resilience requirements of electrical power services.

Huawei has been in the optical networking field for nearly 30 years and has maintained the largest market share in the global optical networking market for 13 consecutive years. Huawei makes full use of its technological prowess to continuously explore the electric power industry. Together with the upstream and downstream of the industrial chain, Huawei has provided secure, stable and reliable all-optical communication network solutions for countries and regions such as China, Thailand, Brazilthe United Arab Emirates and Austriaaccelerating the digital transformation of the electric power industry and reshaping industry productivity.
