Abstract: An optical transceiver module includes a first flexible circuit board and a second flexible circuit board; a light receiving unit and a light transmitting unit disposed on the first flexible circuit board and the second flexible circuit board, respectively; a printed circuit board connected to the first flexible circuit board and the second flexible circuit board, and including a connecting point; and a signal processing unit disposed on at least one of the first flexible circuit board, the second flexible circuit board, and the printed circuit board. The signal processing unit processes optical signals received by the light receiving unit and transmits the signals to the connecting point of the printed circuit board, and processes electrical signals transmitted from the connecting point of the printed circuit board and transmits the signals out through the light transmitting unit.

Abstract: This disclosure provides an optical assembly, comprising a base body and a wave filtering apparatus. A first slot is disposed on an upper surface of the base body. A total internal reflection surface and a connecting part are formed in the first slot. The total internal reflection surface reflects collimated light formed by a first lens from a light emitting apparatus. The wave filtering apparatus comprises a first part removably connected to the connecting portion, and a second portion forming a beam splitting surface. The wave filtering apparatus has a light-pervious optical coating at least on the beam splitting surface of the apparatus, and is configured to split the collimated light reflected from the total internal reflection surface into a first beam and a second beam. The first beam travels towards the side where the third lens is located, and the second beam travels towards a photoelectric detection apparatus.

Abstract: A communication interface module is disclosed, wherein the module may include a circuit board having an electronic communication interface and an optical communication interface; a light source disposed on the circuit board, wherein the light source is indicative of a status of at least one operational condition of the module; a module cover coupled to the circuit board; and a light path extending from the light source on the circuit board to a portion of the module cover visible to a human operator.
