Application Summary AI generated

GB/T 12357.4-2026 specifies the geometric, optical, and mechanical characteristics of category A4 multimode optical fibres, which are plastic optical fibres (POF) designed for short-distance data transmission. It is applied in telecommunications and local area networks (LANs) where high flexibility, ease of installation, and cost-effective connectivity are required, such as in automotive networks, home networking, and industrial control systems. The standard ensures consistent performance for testing and procurement in these environments.
