  • Method of joining a tube to a rod having an annular rib, so as to form an optical fiber preform
    Patent number: 5658363
    Abstract: A method of manufacturing a preform for drawing into an optical fibre comprises positioning a rod within a sleeving tube therefor to form an assembly in which there is an annular space between the rod and tube, and collapsing the tube onto the rod to form a solid cross-section preform. The collapsing step comprises sealingly closing the annular space at one end of the assembly and applying suction to the annular space from the other end of the assembly. The annular space at the one end is sealingly closed by locating the end of the tube at the one end on an annular rib of the rod and fusing the tube end to the rib.
