Optical fibres - Measurement methods and test procedures. Mode field diameter not-eligible For the existing tanksWhat is BS EN IEC 60793145 Optical fibres about? BS EN IEC 60793 is a series on optical fibres. Optical fibres are flexible, transparent fibres made by drawing glass or plastic to a diameter slightly thicker than that of human hair. BS EN IEC 60793145 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.
