Abstract: An optical module includes a housing, a circuit board assembly, an optical assembly, and an optical receptacle. The housing includes first and second housings and an optical fiber adapter. The circuit board assembly includes a rigid circuit board. The optical assembly is fixed on the first housing and includes an optical processing assembly and photoelectric chips. The optical processing assembly includes a wavelength division multiplexer, a lens group located between the wavelength division multiplexer and the photoelectric ship, and a lens group located between the wavelength division multiplexer and the optical receptacle. The photoelectric chips are close to the rigid circuit board and are electrically connected to the rigid circuit board. The optical fiber adapter is arranged at an optical interface of the housing and is integrally formed with the optical interface.

Abstract: A socket set which includes a first socket, a second socket and a combination mechanism is provided. The first socket and the second socket can be combined together. The combination mechanism can retain the first socket and the second socket in a corresponding position, such that the first socket and the second socket are in a cooperative-motion relationship.
