In the second telecommunications window (centered around 1.31 µm), STFs exhibit very low dispersion and propagation losses of about 0.35 dB/km. Use of DSFs can shift the zero dispersion point in the third telecommunication window (centered around 1.55 µm), where the propagation loss is about 0.2 dB/km.

Abstract

The development of low-loss optical silica fibres and reliable semiconductor laser sources in the early 1970s have enabled the practical realisation and massive deployment of optical-fibre communications worldwide. However, high bit-rate transmission is severely limited by the fibre residual loss and dispersion [1]. Fibre non-linearities, on the other hand, can further limit high bit rates over long distances [2]. Figure 5.1 shows a typical attenuation and dispersion spectrum of single-mode, standard-telecommunication fibres (STF) and dispersion-shifted fibres (DSF). In the second telecommunications window (centered around 1.31 µm), STFs exhibit very low dispersion and propagation losses of about 0.35 dB/km. Use of DSFs can shift the zero dispersion point in the third telecommunication window (centered around 1.55 µm), where the propagation loss is about 0.2 dB/km.
