Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional optical module design is used, then basic optical signal conversion is achieved, but signal loss and interference occur in high-speed and long-distance communication systems
Solution Approach 1:
The optical connection component is divided into multiple functional parts: a ferrule assembly for precise optical alignment, a connecting member for secure attachment, and an optical fiber fixing member for stable fiber positioning. This segmentation allows each component to be optimized independently, reducing signal loss at interfaces while maintaining overall transmission reliability.
Solution Approach 2:
The ferrule assembly acts as an intermediary component between the optical fiber and the optical component, providing precise alignment and reducing insertion loss. The connecting member serves as a mediator that securely joins the ferrule assembly to the circuit board, ensuring stable electrical and optical connections that minimize interference in high-speed communication systems.
2Reliability
If optical connection component is added to reduce signal loss, then transmission quality improves, but device complexity increases
Solution Approach 1:
The optical connection component merges multiple functions into a single integrated assembly: the ferrule assembly, connecting member, and optical fiber fixing member are combined into one unified structure that can be installed as a single unit. This merging reduces the number of separate components and assembly steps, thereby limiting the increase in device complexity while still achieving improved signal transmission quality through the specialized functions of each sub-component.

AI summary
An optical module comprising upper and lower shell parts, a circuit board and an optical connection component. The cavity formed by the upper and lower shell parts has only one opening for accommodating the optical connection component and golden fingers on the circuit board. The optical connection component comprises an optical fiber fixing member, a connecting member and a ferrule assembly. The optical fiber fixing member comprises a connection part and an insertion part. An accommodation cavity for inserting the connecting member is formed inside the connection part, and a cavity communicated with the accommodation cavity is formed inside the insertion part. The ferrule assembly is inserted into the cavity via the connecting member, and the optical fiber passes through the accommodation cavity and is connected to the ferrule assembly. An avoidance gap is formed on the connecting member, through which the optical fiber ribbon is passed.
