[0002] In optical fiber communication, in order to convert the electrical signals in the optical fiber communication system into optical signals to achieve high-speed and long-distance transmission of the signals, an optical transmitter is usually installed in the optical fiber communication system. The existing optical transmitter is usually composed of a base, a gasket, a light-emitting LD, a monitoring PD, a lens, a core sleeve and an adapter.

[0003] For example: The utility model patent with application number CN202023119590.X discloses a high-frequency optical transmitter, specifically a tube seat, a tube cap and a lens. The tube seat includes a seat body, a first gasket vertically arranged on the seat body, a second gasket horizontally arranged on the seat body, an LD chip and a plurality of pins arranged on the upper surface of the second gasket. The first gasket is formed with a first metal coating, and the first metal coating includes a first area located on the upper surface of the first gasket and a second area located on the side of the first gasket and connected to the first area. The second area is eutectic welded with a signal transmission pin among a plurality of pins. A second metal coating is formed on the upper surface of the second gasket, and the LD chip is electrically connected to the second metal coating, and the second metal coating is electrically connected to the first area through a plurality of metal wires. By electrically connecting a plurality of metal wires in the first area and the second metal coating, the transmission requirements of high-frequency signals can be met, and the structure is simple and easy to process. In addition, the utility model also discloses a coaxial high-frequency optical transmitting component.

[0017] The heat generated in the base can be quickly introduced into the heat sink through the setting of the thermal conductive column, and the hot air in the heat sink can be quickly introduced into the heat sink through the heat dissipation hole for heat dissipation, thereby improving the heat dissipation efficiency of the light emitter, preventing the light-emitting LD and the monitoring PD from overheating, and effectively extending the service life of the light emitter.

As the control slide 123 moves, the connecting slide 125 will be driven to move. As the connecting slide 125 moves, the two sealing plugs 126 will be automatically closed to seal the light-transmitting hole of the insert 107.
