scope:

This Standard specifies the test methods for structural parameters related to the optical characteristics of optical fibers or jacketed optical fibers of single-mode optical fibers, silica-based multimode optical fibers, multi-component multimode optical fibers, plastic cladding multimode optical fibers, all plastic multimode optical fibers and intraconnection optical fibers (hereafter generically referred to as optical fibers).

NOTE The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 60793-1-1:2017 Optical fibres-Part 1-1: Measurement methods and test procedures-General and guidance

IEC 60793-1-43:2015 Optical fibres-Part 1-43: Measurement methods and test procedures-Numerical aperture measurement
