适用范围：This part of IEC 60793 establishes uniform requirements for measuring the cut-off wavelengthof single-mode optical fibre, thereby assisting in the inspection of fibres and cables forcommercial purposes.This standard gives the methods for measuring the cut-off wavelength of fibre and cableThere are two methods for measuring cable cut-off wavelength, λcc:· Method A: using uncabled fibre;· Method B: using cabled fibre.There is only one method (Method C) for measuring fibre cut-off wavelength, λc.The test method in this standard describes procedures for determining the cut-off wavelengthof a sample fibre in either an uncabled condition (λc) or in a cable (λcc). Three defaultconfigurations are given here: any different configuration will be given in a detail specification.These procedures apply to all category B and C fibre types (see Normative references).All methods require a reference measurement. There are two reference-scan techniques,either or both of which may be used with all methods:· bend-reference technique;· multimode-reference technique using category A1 multimode fibre.
