The general requirements, directions, and methods for qualifying fiber optic cables, connections, and optical fiber splices for use in safety systems of nuclear power generating stations, including fuel reprocessing stations and other related installations, are provided in this standard. Cables, optical fibers, and splices within or integral to other devices (e.g., sensors, instruments, panels, etc.) shall be qualified using the requirements in the applicable device standard or IEC/IEEE 60780- 323:2016, as appropriate. However, the requirements of this standard may be applied to the fiber optic cable and interfaces within these devices.

This standard provides requirements, directions, and methods for qualifying fiber optic cables, connections, and optical fiber splices for use in safety systems of nuclear power generating stations and other nuclear facilities. Cables, connections, optical fibers, and splices within or integral to other devices (e.g., sensors, instruments, panels, etc.) shall be qualified using the requirements in the applicable device standard or IEC/IEEE 60780-323:2016, as appropriate. However, this standard’s requirements may be applied to the fiber optic cable, connections, and optical fiber splices within these devices.

The principal purpose of this standard is to provide specific directions for the implementation of IEC/IEEE 60780-323:2016 for qualification of fiber optic cables, including hybrid cables, connections, optical fiber splices, and environmental seals (related to cables as assemblies).
