摘要： A COB bonding laser diode interface mating device comprises a laser diode and a driver integrated circuit (2). The laser diode includes a light-emitting chip (11). The light-emitting chip (11) is a bare die directly bonded to a circuit board. The driver integrated circuit (2) is a driver chip that is a packaged chip. The light-emitting chip (11) and the driver chip are connected through a capacitor-resistor network (3). The capacitor-resistor network (3) allows the driver integrated circuit (2) to provide a bias current and a modulation current to the laser diode such that the laser diode is in an activated state. The capacitor-resistor network (3) realizes interface mating between the COB bonding laser diode and the driver integrated circuit (2), thereby solving a problem that the interface mating cannot be easily achieved, reducing costs, and improving production efficiency.

The clamping seat, the movable part and the cam are combined, thereby enabling the cam to drive the movable part to slide up and down in a clamping groove of the clamping seat during rotation. When the movable part moves to an upper end, an LC light port of a plastic lens can be inserted into the clamping seat without obstruction. When the movable part moves to a lower end, the LC light port of the plastic lens is limited by a limiting gap of the movable part. When the cam rotates, the cam drives the movable part to slide to the upper end to replace the plastic lens with a new plastic lens. Accordingly, the present invention solves the technical problems of enabling the plastic lens to be easily positioned and bind a PCB, thereby achieving the beneficial effects of improving the quality and the efficiency and reducing the manufacture cost.

摘要： An in-application upgrade method is used for optical module firmware not breaking a service. A storage area for internal programs of an optical module is divided into two areas which are respectively used for storing upgrade and application programs, and is divided into an area for backing up an interrupt vector table of a Boot program. An upper computer is in communication with the optical module. The interrupt vector table is switched, and the jump between the Boot program and the application program is achieved. The method includes extracting the contents of firmware, entering a download mode and updating the firmware. The original firmware is erased, and new firmware is written. An application mode is entered, the upper computer sending an exit command from the download mode. The upgrade program exits and a new application program is executed. The optical module operates normally without interruption.
