Abstract: A small form-factor pluggable module includes a case. The case is provided with a front plate, a top plate connected with the front plate, a bottom plate connected with the front plate and opposite to the top plate, and two side plates connected with the front plate and opposite to each other. The top plate and the bottom plate are respectively connected between the two side plates. The front plate is provided with at least one first opening. The first opening is suitable for being penetrated by at least one connector. A cross-sectional area of the first opening is larger than a cross-sectional area of the connector at where the connector penetrates the first opening.

Abstract: A pluggable connector includes a housing, a handle, a rotating assembly, and a sliding block. The housing has a fastening portion disposed on a top surface of the housing. The handle has a first end portion and a second end portion. The first end portion passes through the housing and is located inside the housing, and the second end portion is located outside the housing. The rotating assembly is rotatably disposed in the housing and coupled to the first end portion of the handle. The sliding block is movably disposed on the top surface of the housing and adjacent to the fastening portion. When a force is exerted to the second end portion of the handle, the first end portion of the handle drives the rotating assembly to push the sliding block, so that the sliding block is moved toward the fastening portion.

Abstract: A receptacle for transceiver optical sub-assembly is configured for optical elements such as a light-emitting unit, a light guide unit, a light-receiving unit and a filter to connect thereto. The receptacle includes a lower receptacle body having a through bore, to which the light-emitting unit is connected; and an upper receptacle body having an axial receiving bore, to which the light guide unit is connected. The upper and the lower receptacle body are movable relative to each other in the x-y plane. The lower receptacle body can be moved relative to the upper receptacle body until an optical signal emitted from the light-emitting unit is optically coupled and collimated with an optical fiber in the light guide unit, and then the upper and lower receptacle bodies are fixedly connected together.

Abstract: A fiber-optic to USB Ethernet converter includes fiber-optic jacks for connecting to optical cables; a USB connecting end for plugging into a USB connector on a computer device; a USB-Ethernet converting module for converting USB serial electric signal format into Ethernet electric signal format and Ethernet electric signal format into USB serial electric signal format; an optical-electric signal converting circuit for converting the Ethernet electric signal format received from the USB-Ethernet converting module into an optical signal for sending out via one optical cable, and converting an optical signal received from one optical cable into the Ethernet electric signal format for sending back to the USB-Ethernet converting module; and a power supply detecting and converting module connected to first and fourth pins in the USB connecting end to acquire and convert +5V DC into 5V or 3.3V for use by the optical-electric signal converting circuit and the USB-Ethernet converting module.
