FITL networks are characterised by the introduction of optical fibre in the access network, up to a certain point where the end users can be reached using standard telephony twisted pair carrying all services. The fibre penetration level (i.e. low for to the home the fibre is reaching) is determined by the available loop technology at the time of deployment, the service mix and take ratio, and of course the cost of the network, not only equipment cost, but also the installation and operational cost. With today's emerging technologies, fibre-to-the curb access networks are becoming feasible and economically justifiable, even for moderate penetration of high bit rate services. A general characteristic of these networks is that the last copper drop, between the optical network termination and the subscriber house, has to use the existing cabling for delivering POTS or NISDN services. The access network will in this way be upgraded to deliver video and other ATM based services to the subscriber
