<p>An apparatus is provided for introducing at least one optical fibre member (6) into a tubular passageway. The apparatus comprises a pressure vessel (1) for receiving the optical fibre member (6), the vessel (1) either containing compressed air or other gas or being provided with an inlet (2) by means of which compressed gas can be introduced. The vessel is connected to the passageway via a fibre-introducing device, e.g. a venturi (11) or a mechanical device, which creates slack in the optical fibre member.</p> |
