Process for manufacturing a multi-core optical fibre

摘要

The process of the invention is a MCVD-type fibre manufacturing process which enables the layer of core deposited inside a starter quartz tube 1 to be etched by introducing gas and heating by means of a torch having two nozzles 25, 26 disposed on either side of the tube 1. This process enables multi-core optical fibres to be obtained after necking-down (diameter reduction) and drawing. Application to the manufacture of optical fibres. <IMAGE>
