Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A dark fibre or unlit fibre are unused optical fibres, available for use in fibre-optic communications. The term dark fibre was originally used when referring to the potential network capacity of telecommunication infrastructure, but now also refers to the increasingly common practice of leasing fibre optic cables from a network service provider. One reason that dark fibre exists in well-planned networks is that much of the cost of installing cables is in the civil engineering work required. This includes planning and routing, obtaining permissions, creating ducts and channels for the cables, and finally installation and connection. This work usually accounts for more than 60% of the cost of developing fibre networks. For example, in Amsterdam's city-wide installation of a fibre network, roughly 80% of the costs involved were labour, with only 10% being fibre. It therefore makes sense to plan for, and install, significantly more fibre than is needed for current demand, to provide for future expansion and provide for network redundancy in case any of the cables fail.show more
