Title: Apparatus for treating optical fibers by spark erosion

Abstract: The disclosed apparatus has a spark gap at which optical fibers are to be exposed to spark erosion treatment. The spark gap receives electrical energy from a spark-impulse transformer with the secondary winding of which it is connected by means of a length of coaxial charging cable. A firing circuit has its output connected with the primary winding of the transformer and its input connected with a control circuit which includes a multi-vibrator that can be adjusted as to its pulse-repetition frequency.
