ABSTRACT:
A biconic optical fiber connector (20) comprising two plugs (24--24) each having truncated conically shaped end portions (30--30) for terminating optical fibers to be connected and a sleeve (66) in which the plug eng portions are received is provided with an attenuator (70) which results in low reflected power. The attenuator comprises a plate-like element which is disposed between the plug end portions. Advantageously, the plugs are seated in the sleeve and the thickness and mounting of the attenuator cooperate to cause the plug ends to engage the attenuator when the plugs are seated in the sleeve cavities. Also, the attenuator is supported within the sleeve so that it is capable of slight movement in a direction parallel to a longitudinal axis (91) of the sleeve to self-adjust, if necessary, as the plug end portions are inserted and become seated in the sleeve.
