ABSTRACT:
A torch specifically adapted for the manufacture of optical fiber couplers is provided. The torch has a rod and nozzle of, preferably machinable, ceramic. The rod has an inlet for connection to a gas supply source, an outlet, and a gas channel connecting the inlet to the outlet. The nozzle has an inlet for receiving gas from the rod outlet, and an enlarged outlet connected to the nozzle inlet for discharging gas for ignition. The shapes and dimensions of the parts of the torch can be modified for the specific manufacturing requirements for an optical fiber coupler. During the manufacture of optical fiber couplers, the torch can be maintained in an ignited state so that the fusing of optical fibers can be performed uniformly and reliably.
