	The first 7 chapters (Introduction, Fundamental characteristics of optical fibres, Optical fibre fabrication techniques, Optical fibre cables, Splices and connectors for optical fibre communications, Test methods, Sources and detectors for optical fibres communications) deal principally with the analysis of the components necessary for buiding an optical fibre communications system.

The other chapters (Transmission systems using optical fibres, The Application of optical fibres in the local and rural networks, The Application of optical fibres in the junction network, The Application of optical fibres in the trunk network, The Application of optical fibres in submarine cable systems, Conclusion) give the potential applications of optical fibres in various parts of the telecommunications network.
