ABSTRACT:
The attenuator includes an externally threaded sleeve for receiving standard ferrules within its bore at opposite ends, an internally threaded adjuster for threaded engagement about the sleeve and a ferrule locking nut threadedly engageable about the adjuster for clamping a ferrule at one end of the sleeve between the adjuster and ferrule locking nut. By relatively threading the sleeve and adjuster, the ferrule may be displaced relative to the sleeve whereby the end face of the optical fiber carried thereby is adjustably spaced from the end face of an optical fiber carried by a ferrule fixed on the sleeve at the opposite end thereof.
