Claim Text:
1. A communication light detector for being removably attached to a communication light visualizing adaptor with a light extraction hole so as to detect whether a communication light is transmitted through the communication light visualizing adaptor by receiving through the light extraction hole a leak light as a part of the communication light transmitted through the communication light visualizing adaptor, the detector comprising: a detector main body comprising a bottom surface that faces the light extraction hole, mounts a light-receiving element and is formed so as to adapt to a first communication light visualizing adaptor; and an attachment that comprises a front surface facing the bottom surface, a back surface facing the light extraction hole and a though-hole formed penetrating from the front surface to the back surface so that the light-receiving element is exposed from the front surface to the back surface, the front surface being formed so as to adapt to the bottom surface and the back surface being formed so as to adapt to a second communication light visualizing adaptor.
