Abstract: An optical transceiver includes a positioning element, a fiber connecting segment, a base and a housing. The positioning element has a first positioning part. The fiber connecting segment tightly fits to the positioning element. The housing supports at least one optical transceiving element and is connected to the positioning element. The base has a second positioning part and is configured for supporting the positioning element and the fiber connecting segment. The first positioning part and the second positioning part define the position of the fiber connecting segment.

Abstract: An optical module includes a first light-guide element, an optical element, a first optical fiber, and a beam splitter. The first light-guide element includes a first surface and a second surface. The optical element corresponds to the first surface. The first optical fiber is contacted with the second surface. The beam splitter is attached to the first surface, the beam splitter partially reflects and partially transmits a light beam striking thereon. A refractive index of the beam splitter is different from a refractive index of the first light-guide element.

Abstract: An optical splitting device includes a body and an optical condensing member. The optical condensing member is disposed on the body, and includes a first light incident surface and a second light incident surface. The second light incident surface is discontinuously adjacent to the first light incident surface.
