Abstract: A method and assembly of providing a building or other location with an optical fibre ribbon cable having a plurality of optical fibres terminated by a connector is provided. The method and assembly enable optical fibre ribbon cables to be terminated in a factory rather than on site, and then to be installed by blown fibre methods, even when the ribbon cable is terminated by connectors that are too large to be inserted in the duct. The assembly includes an optical fibre ribbon cable having a plurality of optical fibres, a unitary insert for a connector that terminates at least one end of the cable, and a housing for the connector which can be located about the insert to form a composite connector. The optical fibre ribbon cable as thus terminated is capable of being propelled along a duct by fluid drag of a gaseous medium.
