Abstract: An optical electrical connector includes a casing, a printed circuit board, an electronic chip, a photoelectric conversion component, and a heat sink device. The casing includes an electrical port and an optical port. A receiving space is defined between the electrical port and the optical port. The printed circuit board extends longitudinally along a first direction. The printed circuit board includes a main body portion located in the receiving space and a front end portion exposed in the electrical port. The electronic chip, the photoelectric conversion component and the heat sink device are all accommodated in the receiving space. The electronic chip and the photoelectric conversion component are not only disposed on the printed circuit board, but also electrically connected to the printed circuit board. The heat sink device is disposed on the casing and faces the electronic chip for conducting the heat accumulated on the electronic chip.

Abstract: Disclosed are a co-packaged integrated optoelectronic module and a co-packaged optoelectronic switch chip. The co-packaged integrated optoelectronic module includes a carrier board, and an optoelectronic submodule, a slave microprocessor and a master microprocessor disposed on and electrically connected to the carrier board. In the optoelectronic submodule, a digital signal processing chip converts an electrical analog signal into an electrical digital signal, an optoelectronic signal analog conversion chip converts an optical analog signal into the electrical analog signal to the digital signal processing chip, and an optical transceiver chip receives and transmits the optical analog signal to the optoelectronic signal analog conversion chip. The slave microprocessor monitors operation of the optoelectronic submodule.

Abstract: A beam-splitting integrated optical element including a shell, at least one first lens, and at least one second lens is provided. The shell includes a first lens surface, a second lens surface, at least one first reflective surface, and at least one second reflective surface. A bottom edge of each first reflective surface and a bottom edge of each second reflective surface are not connected to each other. The at least one first lens is disposed on the first lens surface. The at least one second lens is disposed on the second lens surface, and each second lens has a second optical axis. Each second reflective surface is located at at least one side of the corresponding second optical axis and located on a transmission path of only a portion of a first beam.

Abstract: A detection system that performs in a passive optical network is disclosed. The detection system uses a central office to provide detection signals to corresponding fiber branches for obtaining different reflected signals based on different optical network models. Hence, the central office can determine whether fiber branches in the passive optical network has a fault and where the fault is according to the reflected signals.
