Dark fibre is optical fibre infrastructure (cabling and repeaters) that is currently in place but is not being used. Data broadcasting - Data can be broadcast or transmitted to users over various wireless and cable mediums. The most typical are radio broadcasts (VHF, UHF, satellite) and cable broadcasts (such as simple cable television).
Fibre optic cable that has been laid but is not currently used.... more on: Dark fibre
Fibre optic cable that has been purchased by a non carrier/ISP in order to lay (into the ground) and light it for their own use. Dark fibre does not have any transmission equipment attached to the fibre links at this point in time. Dark fibre becomes lit fibre once it is being lit (through optical transmission equipment) and managed by a party (usually a carrier/ISP).
Unconfigured optical fibre laid ready for users to install their own transmission equipment. Because no light source has been applied, it is 'dark'.
Fibre optics strands absent the electronic components that transmit telecommunications traffic through such fibres.
An optical fibre which has been installed but is not used.
Dark Fibre describes fibre through which no light is transmitted. It is installed fibre cable that is not carrying a signal.
The term given when optical fibres are implemented and ready to be used.
is an optical fibre infrastructure that is in place but is not connected to in-service transmission equipment and therefore is without any optical or electronic signalling.
Fibre optic cable without the necessary equipment to transmit a telecommunication signal over the fibre.
Inactive fibre-optic cable without electronics or optronics.
