ABSTRACT OF THE DISCLOSURE: There is disclosed a method anal a system for laying out optical fibres across an aperture in a wall separating a high pressure zone from a low pressure zone. It involves a plug member sealingly mounted across the aperture and formed with an axial through fibre passage having a conical first portion and a second portion of constant cross-section. A co- nical wedge member is freely inserted into the first passage portion and is formed with a series of grooves on its outer surface leading into the second passage portion. A plurality of optical fibres are divided into fractions and each fraction is received into one of the grooves; all fibres being there- after collected into the second passage portion. Plastics ma- terial is introduced in the grooves and in the second passage portion to completely embed the fibres while adhering to the walls of the grooves and of the second passage portion. In this manner, the frictional resistance of the plastics material is greatly increased, allowing an appreciably larger pressure differential between the two pressure zones.
