Why can cables with different naming standards be used interchangeably in global infrastructure?

While the alphanumeric codes vary, the core physical and optical parameters are harmonized under international standards bodies like the ITU-T and IEC.

Performance Alignment: A “GYTS” cable is functionally equivalent to an international “Corrugated Steel Tape Armored Loose Tube Cable” as long as both meet the IEC 60793 (fiber) and IEC 60794 (cable structure) specifications.

Standardized Geometry: The cladding (125µm) and core diameters (9µm, 50µm, or 62.5µm) are universal, ensuring that connectors and splicing equipment work seamlessly regardless of the cable’s regional origin.
