Abstract

A bi-directional optical module includes a substrate, at least one first light-emitting diode (LED), and at least one second LED. The first LED is disposed on a surface of the substrate. The first LED has a first reflection surface and a first light-outlet surface that are opposite to each other, and the first light-outlet surface is away from the substrate relative to the first reflection surface. The second LED is disposed on the same surface of the substrate. The second LED has a second reflection surface and a second light-outlet surface that are opposite to each other, and the second light-outlet surface is close to the substrate relative to the second reflection surface. The substrate has at least one light-transparent area that is not occupied by the first LED and the second LED.
