Abstract:
1. A variable attenuator assembly for attenuating optical signals transmitted between a first and a second optical fibers, comprising: a plug-type connector terminating the second optical fiber; a coupling sleeve open at two opposite ends; and a variable attenuating connector (VAC) terminating the first optical fiber, comprising: wherein rotating the knob induces a first linear displacement of the knob with respect to the connecting member and the stationary housing and a second linear displacement of the holder with respect to the knob, the first linear displacement being dependent upon the first screw pitch and the second linear displacement being dependent upon the second screw pitch, whereby the optical fiber is moved with the holder an overall displacement corresponding to the sum of the first and second linear displacements, wherein a biasing element is radially arranged between said stationary housing and said ferrule holder to urge the ferrule holder forwardly; wherein said stationary housing is of a one-piece integrally formed type, and a discrete clip is inserted into said stationary housing to abut against a rear end of the biasing element.
