Method of drawing microstructured optical fibres from a preform

摘要

A method of manufacturing a microstructured fibre, comprises: providing a preform comprising a plurality of elongate holes; mating at least one, but not all, of the holes with a connector to connect the hole(s) to an external pressure-controller; drawing the preform into the fibre whilst controlling gas pressure in the hole(s) connected to the pressure-controller. The connector is also claimed.
