Abstract

A method is described for introducing one or more optical fibre members (1) into a tubular passageway (2). The method involves passing a current of fluid, preferably air, into and through a venturi (6) the downstream side of which communicates with the passageway (2). The optical fibre member (1) is introduced into the venturi (6) via a hypodermic tube (7) and then into the passageway (2). Apparatus for carrying out the method are described.
