SEALED TUBE COUPLING FOR OPTICAL FIBER TUBES

摘要

A coupling for conduit tubes (16, 16') for carrying optical fibres or optical fibre units, comprising a body which has two entries (18, 18') , both entries having associated therewith means (20, 20') to secure the body to conduit tubes inserted into the entries, the body being further provided with a space or chamber (42) between the entries through which one or more optical fibres or optical fibre units may pass, the body having a third entry (34) arranged to enable insertion of sealing material into the space, and means, such as deformable seals (26, 26'), to maintain the sealing material within the space .
