摘要： Embodiments of the present invention disclose a coaxial photodetector comprising an optical port adapter (21), a filtering assembly (22), a connecting tube body (23), a transistor-outline can (TO-CAN) (24) including a photodiode, wherein two ends of the connecting tube body (23) are separately connected to the optical port adapter (21) and the TO-CAN (24), and the filtering assembly (22) is in the connecting tube body (23). The optical port adapter is configured to connect to an optical fiber, and a light beam from the optical fiber is guided to the filtering assembly by the optical port adapter, and is output to the photodiode after filtered by the filtering assembly. A light beam can be filtered, so that the photodiode in the coaxial photodetector has a function of receiving a light beam having a particular wavelength, and an optical loss caused to an optical signal converted between free space and the optical fiber can be reduced.
