Abstract

The lens (311) of the plug (31) converts an optical signal from the optical cable (20) into light having a predetermined divergence angle and emits the light. The plug housing (315) is fixed with an optical cable (20) and a lens (311). On the emitting surface (20a) side of the optical cable (20), a lens (311) is placed at a position where an optical signal from the optical cable (20) becomes to have a predetermined divergence angle. The light signal emitted from the plug (31) is divergent when entering the eyeball of a nearby person, and thus is prevented from adversely affecting visual functions and the like.

Description

technical field [0001] The present invention relates to an optical connector, an optical cable, and an optical communication device that prevent optical signals from adversely affecting visual functions and the like. Background technique [0002] In optical communication using laser light, optical cables are connected by, for example, optical connectors. In a well-known optical connector, a lens for collimating optical signals communicated between the plug and receptacle is provided on one of the plug side and the receptacle side, and a lens for collecting parallel light is provided on the other side. . As described above, if communication is performed between the plug and the receptacle by using parallel light, optical communication can be performed without highly accurately positioning the end face of the optical cable at a predetermined interval to face each other with the photodetector, etc., and Inexpensive optical connectors are available. [0003] Furthermore, in P...
