OPTICAL CONNECTOR, CABLE, AND OPTICAL COMMUNICATION DEVICE

Lenses 311a that collect an entering light signal to a light transmission path or a light detection unit is provided in a plug housing 315 coupled to a transmission side optical connector of the light signal. In the housing 315, the light transmission path or the light detection unit is retained for each lens 311a. In the housing 315, attachment portions 316L, 316R that attach the housing 315 to the transmission side optical connector is provided in an array direction of a plurality of lenses. In the lenses 311a, an entrance range of the light signal that is collectable to the light transmission path or the light detection unit is expanded in a direction orthogonal to the array direction of the lenses. Even if force is exerted in a turning direction about an axis at the array direction LP of the lenses, the entering light signal can be collected to the light transmission path or the light detection unit, in order to perform robust optical communication.
