Optical fibres -- Part 1-34: Measurement methods and test procedures - Fibre curl

This part of IEC 60793 establishes uniform requirements for the mechanical characteristic: fibre curl or latent curvature, in uncoated optical fibres. Fibre curl has been identified as an important parameter for minimizing the splice loss of optical fibres when using passive alignment fusion splicers or active alignment mass fusion splicers. Two methods are recognized for the measurement of fibre curl, in uncoated optical fibres: method A: side view microscopy; method B: laser beam scattering. Both methods measure the radius of curvature of an uncoated fibre by determining the amount of deflection that occurs as an unsupported fibre end is rotated about the fibre's axis. Method A uses visual or digital video methods to determine the deflection of the fibre while method B uses a line sensor to measure the maximum deflection of one laser beam relative to a reference laser beam. By measuring the deflection behaviour of the fibre as it is rotated about its axis and understanding the geometry of the measuring device, the fibre's radius of curvature can be calculated from simple circular models, the derivation of which are given in Annex C. Both methods are applicable to types A1, A2, A3 and B optical fibres as described in the IEC 60793 series. Method A is the reference test method, used to resolve disputes.

Fibres optiques -- Partie 1-34: Méthodes de mesure et procédures d'essai - Ondulation de la fibre

Etablit des perscriptions uniformes applicables à l'ondulation des fibres ou à la courbure latente des fibres optiques nues. Ce paramètre est important de reduire des pertes par épissures lors de l'utilisation de soudeuses par fusion. Deux méthodes sont reconnues: (a) par microscopie latérale, (b) par diffusion de rayons laser. La méthode (a) est la méthode d'essai de référence en cas de litiges.
