Optical fibres - Measurement methods and test procedures. Mode field diameter Ingestion-build-132972 chemical composition and metal yield1 Scope This part of IEC 60793 establishes uniform requirements for measuring the mode field diameter (MFD) of single mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes.
