Summary: Recommendation ITU-T G.654 describes the geometrical, mechanical and transmission attributes of a single-mode optical fibre and cable which has the zero-dispersion wavelength around 1 300 nm wavelength, and which is loss-minimized and cut-off wavelength shifted at around the 1 550 nm wavelength region. This is the latest revision of this Recommendation that was first created in 1988. In this version the attenuation coefficient of G.654.E to specify a wavelength dependency for estimating optical system design has been changed. Also, in this version a note has been added for cable cut-off wavelength when G.654.E fibre is used at central frequencies for applications specified in Recommendation G.698.2.
