​​Abstract: LONGREACH Long-Distance Connection Solutions​​ As enterprise networks shift to "edge-driven" models, remote power demands for devices (switches, routers, surveillance systems) beyond 100 meters are rising. IEEE 802.3’s 100-meter PoE limit drives the need for extended solutions. LONGREACH’s high-performance copper cables overcome this, supporting 90W PoE up to 250 meters (21AWG, 20℃). Key benefits: simplified deployment, efficient power delivery, network security, and green efficiency. It addresses challenges like signal attenuation, voltage drop, and costly traditional setups (extra cabinets/fiber). This solution bridges edge device deployment with reliable power/signal transmission, cutting infrastructure costs and enabling future tech (5G, IoT).

From September 4 to 6, 2024, the 2024 (43rd) Communication Line Academic Annual Conference of the China Society of Communications was held in Weihai, Shandong Province，China. The paper 《Research on Temperature Rise Characteristics of Data Cable with DC Power Supply》which was jointly accomplished by Dr. Fang He (the chief expert of Zhaolong Interconnect Connection System), Zhou Qinyang and Shen Jintao from Dr. He’s team, received the first prize during the conference.

On April 21, 2021, the “Power over Ethernet (PoE) Engineering Technical Standards” review meeting was organized by the Green Information Integration Technology Committee (GIIT) of the China Electronic Energy Saving Technology Association(CEESTA) and held at the venue of the Shanghai East China Archi
