Optical connector and adaptor kit for selective attenuation of signals in optical fiber circuits

摘要

A selected value of attenuation can be inserted in an expanded beam fiber optic connector or coupling component. The attenuator includes a spacer member having planar ends slightly inclined to one another so that the axes of the lenses in the two halves of the connection are caused to be misaligned when the spacer member is disposed between the lenses. An adapter kit is disclosed for modifying an existing connector lacking the ability to selectively attenuate. The kit includes a housing extension member and a spacer member.
