1 Scope This technical report provides guidelines concerning single-mode fibre compatibility. A given type of single-mode fibre, for example B4, may 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. This guideline indicates the items that should be taken into account when planning to connect: (1) different implementations of single-mode fibres of the same type, e.g. different implementations of type B single-mode fibres, and (2) single-mode fibres of different types, e.g. B1.1 with B4. See IEC 60793‑2‑50 for the attributes and definitions of single-mode fibre. The attributes and definitions of fibres covered in this technical report are given in Table 1.
