TECHNICAL FIELD
[0001] The utility model relates to optical communication technical field, especially a kind of optical device convenient to connect. BACKGROUND
[0002] In the field of optical communication technology, optical devices are key components, and their performance directly affects the performance of optical communication systems. Optical devices not only need to be responsible for the core functions of optical signal conversion, amplification, modulation and demodulation, but also bear the heavy responsibility of ensuring accurate transmission of signals in complex fiber networks.
[0003] In order to realize these functions, Combo devices must be physically fixed and electrically connected to printed circuit boards (PCB) to ensure that optical signals can be converted into electrical signals stably and efficiently, and then transmitted stably in the system, improving the overall performance and reliability of the system.
[0004] However, in the traditional connection method, the industry generally uses soldering to weld Combo devices with PCB boards. Although this method can achieve stable connection between the two to some extent, its inherent limitations are increasingly prominent. First, the welding process is relatively complex, requiring precise control of welding temperature, time and amount of solder, which requires higher skills for operators. Second, the welding efficiency is low, especially in large-scale production, the welding process may become a bottleneck that restricts production efficiency. More importantly, once the welding is completed, the connection between the Combo device and the PCB board is difficult to separate, which brings great inconvenience to subsequent maintenance and replacement.
[0005] In the current context of rapidly changing optical communication technology, the update and iteration speed of Combo devices is increasing, and higher convenience is required for maintenance and replacement. The traditional welding method is not detachable, which often leads to the need to replace the PCB board together when the Combo device needs to be replaced, which not only increases maintenance costs, but also causes unnecessary resource waste.
