Optical fibres - Part 1-45: Measurement methods and test procedures - Mode field diameter IEC 60793-1-45:2001 ED1

Publication date:   Jul 31, 2001

Scope

Establishes requirements for measuring the mode field diameter (MFD) of fibres. Four methods are described: (a) direct far-field scan: (b) variable aperture in the far field: (c) near-field scan: (d) bi-directional backscatter using an optical time domain reflectometer. All four methods apply to type B single-mode fibres, operating near 1310 nm or 1550 nm.
