Optical fibres -- Measurement methods and test procedures

PUBLISH DATE 2004
PAGES 34
BSI BS EN 60793-1-40:2003

Establishes uniform requirements for measuring the attenuation of optical fibres.

Four methods are described:

  • (a) cut-back,
  • (b) insertion loss,
  • (d) backscattering,
  • (d) modelling spectral attenuation.
Methods (a), (b) and (c) apply to all categories of class A multimode fibres and class B single-mode fibres.

Method (c), backscattering, also covers the location, losses and characterization of point discontinuities.

Method (d) has been demonstrated only on class B fibres.
