Abstract
To provide a reflected light measurement device capable of efficiently performing disconnection inspection on an optical connector, and a plurality of optical fibers. The reflected light measurement deviceincludes a laser light source, a beam splitterthat branches measurement laser light L into measurement laser light Lto be transmitted and reference laser light Lto be reflected, a reference mirrorincluding an optical path length varying mechanism capable of adjusting an optical path length of the reference laser light L, an optical path length switching unit, and switches the optical path length of the reference laser light Lto a plurality of fixed lengths, and a photometerthat receives measurement laser light L' reflected at defect sites Dand Dsuch as disconnection inside connectors Cand C, and reference laser light L′ reflected by the reference mirror
