METHOD OF DRAWING MICROSTRUCTURED GLASS OPTICAL FIBERS FROM A PREFORM, AND A PREFORM COMBINED WITH A CONNECTOR

摘要

A method of manufacturing a microstructured fibre, includes: providing a preform having 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.
