Abstract
Procedimento per la realizzazione a fusione di un attenuatore per segnali ottici utilizzando uno spezzone di fibra ottica, comprendente le seguenti fasi di:a) fusione dello spezzone di fibra ottica;b) manipolazione dello spezzone di fibra ottica durante la fusione;c) inserimento dello spezzone di fibra ottica in un adattatore meccanico per il collegamento con due connettori standard rispettivamente attestati sulle parti terminali di due fibre ottiche, in cui la fase di manipolazione dello spezzone di fibra ottica durante la fusione viene eseguita sottoponendo lo spezzone di fibra ottica sia ad un disallineamento assiale che ad un disallineamento angolare.
