Abstract: A removal unit includes a latch and a tab separably connectable to the latch. The latch includes latch arms each including a connection hole and an opening extending from the connection hole and being smaller than the connection hole. The tab includes a body, tab arms extending from the body, and protrusions provided on the tab arms to protrude toward each other. The protrusions each include a connecting part and an engaging part extending from the connecting part and being larger than the connection hole. The connecting part is provided on the tab arm, and configured to be placed into the connection hole. The connecting part has a width in a first direction smaller than the width of the opening and a length in a second direction perpendicular to the first direction smaller than the diameter of the connection hole and greater than the width of the opening.

Abstract: An optical waveguide module includes an optical waveguide sheet including multiple optical waveguides, and a light-emitting device and a light-receiving device each positioned over a surface of the optical waveguide sheet. At least one of the optical waveguides includes a first mirror, a second mirror, and a slit. The first mirror is configured to reflect light entering the corresponding optical waveguide from its first end to the light-receiving device or to reflect light emitted from the light-emitting device toward the first end of the corresponding optical waveguide. The second mirror is configured to reflect light entering the corresponding optical waveguide from its second end toward the surface of the optical waveguide sheet. The slit is provided between the second mirror and the second end of the corresponding optical waveguide. The corresponding optical waveguide is discontinuous across the slit.
