Abstract
An apparatus is provided for introducing at least one optical fiber member into a tubular passageway. The apparatus comprises a pressure vessel for receiving the optical fiber member, the vessel either containing compressed air or other gas or being provided with an inlet by means of which compressed gas can be introduced. The vessel is connected to the passageway via a fiber-introducing device, e.g. a venturi or a mechanical device, which creates slack in the optical fiber member.
