ISO/IEC 11801 fiber optic labels: OS for singlemode, OM for multimode. OM1-OM4 & OS1-OS2 vary by performance & material. Some designations differ.
Fiber optic cables are categorized by how they transmit light: Single-mode (OS1/OS2): Guides light in a single, straight path through a tiny 9µm core, enabling long-distance, high-speed transmission. In ISO/IEC 11801 and EIA/TIA standards five types of Multimode –. These are fiber optic cable designations that originated in the international ISO/IEC 11801 standard. The designations indicate a particular level of performance. OS levels are for singlemode fiber and OM levels are for multimode fiber. 652D also belong to the usual OS1 fibers. While copper reaches its physical limits, fiber continues to evolve, scaling from 1Gbps to 400Gbps and beyond.
