What does the ISO/IEC 11801 specification refer to?

The ISO/IEC 11801 specification primarily refers to structured cabling systems for use in various types of buildings and environments. It encompasses guidelines for both copper and fiber optic cabling types, outlining the performance requirements and standardization for these cabling systems. Specifically, it establishes classifications for different types of fiber cables, which is crucial for ensuring compatibility and performance across various applications within telecommunication and data networks.

By detailing fiber type designations, ISO/IEC 11801 helps ensure that network designers and installers can select the appropriate fiber types for their specific applications, facilitating effective communication and data transmission. This makes it essential for professionals working in the field of fiber optics to understand these designations to comply with industry standards and achieve optimal network performance.
