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 methods for measuring the cut-off wavelength for uncabled or cabled single
mode telecom fibre. These procedures apply to all category B and C fibre types (see Normative
references).
There are three methods of deployment for measuring the cut-off wavelength.
" Method A: Cable cut-off using uncabled fibre 22 m long sample, »cc
" Method B: Cable cut-off using cabled fibre 22 m long sample, »cc
" Method C: Fibre cut-off using uncabled fibre 2 m long sample, »c
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.
