Abstract (en)
An apparatus is employed for heating a silica optical fibre (10) on a fibrating installation, which apparatus is intended to be arranged at the output of the fibrating oven in order to bring the said fibre to a temperature above 1,000 DEG C; it is characterised in that it comprises a microwave generator associated via coupling means with a resonant cavity formed by a metal wire wound into a helix (20) and fixed at its two ends (23, 24) respectively to two so-called short-circuit metal plates (25, 26), the said fibre being able to pass substantially along the axis (21) of the said helix. <IMAGE>
