ABSTRACT:
A fiber optic attenuator (11) comprising fiber optic termini (13, 13a) having bodies (23, 23a), with end faces (27, 27a) and optical fibers (29, 29a). The optical fibers (29, 29a) have distal ends (31, 31a) adjacent the end faces (27, 27a). A connector in the form of an alignment sleeve (15), a housing (17) and a coupling (19) connects the termini (13, 13a) with the end faces (27, 27a) in confronting relationship, and the distal ends (31, 31a) optically coupled. A screw (21) carried by the housing (17) can relatively displace the distal ends (31, 31a) in a generally radial direction to provide attenuation of the optical signal transmitted between the termini (13, 13a).
