Optical fibres - Measurement methods and test procedures. Cut-off wavelength has-corrigendum If any soluble contaminants remain1 Scope This part of IEC 60793 establishes uniform requirements for measuring the cut off wavelength of single mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. This standard gives the methods for measuring the cut off wavelength of fibre and cable There are two methods for measuring cable cut off wavelength, cc: Method A: using uncabled fibre; Method B: using cabled fibre. There is only one method
