scope:

This document provides guidelines concerning single-mode fibre inter-compatibility.

A given category of single-mode fibre, for example B-655, can have different implementations by suitably optimising several of the following parameters: mode field diameter (hence effective area), chromatic dispersion coefficient, slope of the chromatic dispersion curve, cable cut-off wavelength.

These guidelines indicate the items that are taken into account when planning to connect

1) different implementations of single-mode fibres of the same category, for example different implementations of Class B single-mode fibres, and

2) single-mode fibres of different sub-categories, for example B-652.B with B-655.C.

See IEC 60793-2-50 for the attributes and definitions of single-mode fibre. The attributes and definitions of fibres covered in this document are given in Table 1.

This document does not consider the connection of fibres with the same category from different manufacturers, which is already considered by the standardisation procedure.
