Annex A (normative) - Requirements specific to
method A - Mode field diameter by direct
far-field scan
Annex B (normative) - Requirements specific
to method B - Mode field diameter by
variable aperture in the far field
Annex C (normative) - Requirements specific to
method C - Mode field diameter by
near-field scan
Annex D (normative) - Requirements specific to
method D - Mode field diameter by optical
time domain reflectometer (OTDR)
Annex E (informative) - Sample data sets and
calculated values
Provides 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.
