This Recommendation describes a single-mode optical fibre and cable, which has the zero-dispersion wavelength around 1 300 nm, which is loss-minimized and cut-off shifted at a wavelength around 1 550 nm and which is optimized for use in the 1 530-1 625 nm region.

This very low loss cut-off shifted fibre (CSF) can be used for long-distance digital transmission applications, such as long-haul terrestrial line systems and submarine cable systems using optical amplifiers. The geometrical, optical (attenuation, cut-off wavelength, chromatic dispersion and polarization mode dispersion (PMD), etc.), transmission and mechanical characteristics of this CSF are described.

Some provisions are made to support transmission at higher wavelengths up to 1 625 nm. The geometrical, optical, transmission and mechanical parameters are described in three categories of attributes:

• fibre attributes that are retained throughout cabling and installation;

• cable attributes that are recommended for cables as they are delivered;

• link attributes that are characteristics of concatenated cables, describing estimation methods of system interface parameters based on measurements, modelling or other considerations. Information for link attributes and system design are given in Appendix I.

This Recommendation, and the different performance categories found in Tables 1 to 5 in clause 8, are intended to support the following related-system Recommendations:

• [b-ITU-T G.696.1];

• [b-ITU-T G.957].

The meaning of the terms used in this Recommendation, and the guidelines to be followed in the measurements to verify the various characteristics, are given in [ITU-T G.650.1] and [ITU-T G.650.2]. The characteristics of this fibre, including the definitions of the relevant parameters, their test methods and relevant values, will be refined as studies and experience progress.
