The China Engineering and Consulting Association (CEDA) recently released China’s first Passive Optical LAN (POL) Engineering Technical Standard. The initiative is aimed at standardising and promoting POL deployment in smart buildings and campuses, and helping design institutes and integrators to improve design capabilities, construction quality, and delivery efficiencies. As a member of the CEDA, China’s Huawei actively prepared content related to POL system planning and design and equipment configurations to accelerate the release of the standard.

In recent years, technologies such as cloud computing, big data, and the Internet of Things (IoT) have been widely used to make cities smarter. According to Huawei’s Global Industry Vision 2025, 85% of enterprise applications will run on the cloud, and campus traffic will shift from horizontal to vertical, by 2025. According to the company, a POL features a simplified architecture, and is naturally suitable for enterprise cloudification. Compared with traditional campus switch networks, the POL solution requires 80% fewer extra-low voltage equipment rooms, reduces required cabling space by 90%, reduces power consumption by 80%, and reduces the project total cost of ownership by 30%.

To meet the urgent standardisation requirements of the POL industry market, the Engineering Intelligent Design Branch of the CEDA, as the chief editing unit, has organised enterprises and institutions such as China Electronics Engineering Design Institute and Huawei Technologies Co., Ltd. to develop the POL Engineering Technical Standard. The standard systematically describes and defines POL design and construction specifications across six dimensions, including planning and design, equipment configuration, construction, commissioning and trial running, and checking and acceptance. It aims to improve the quality and efficiency of POL design and construction, and tackle pain points hampering the development of the POL industry.

Zhang Xu, Vice Secretary General of the Engineering Intelligent Design Branch of CEDA, said: “The POL Engineering Technical Standard aims to improve the quality and efficiency of POL design, construction, and delivery. The branch will promote the standard across the industry and its application in key projects, so that smart buildings and a better information experience can be delivered more efficiently.”

“The release of the POL Engineering Technical Standard will promote the application of POL. It marks a key milestone of POL industry development, and sets a benchmark for the global industry,” added Joe Zhou, President of the Enterprise Domain of Huawei Transmission & Access Product Line.
