Optical Transceiver Compact Design via Integrated Fiber Segment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transceivers are not suitable for applications with limited space due to their size, as they require additional space for the fiber segment and connector, which occupy extra space and are not compact enough.
Innovation Solution
An optical transceiver design that includes a positioning element, a fiber connecting segment, a base, and a housing, where the positioning element and base define the position of the fiber connecting segment, allowing it to fit tightly without additional fibers, and the segment's end surface is angled relative to its center axis to prevent shifting and improve coupling, minimizing the overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fiber segment and fiber connector are configured outside the transceiver, then the optical signal transmission function is achieved, but the overall size of the optical transceiver increases
Solution Approach 1:
The fiber connecting segment is integrated directly into the transceiver body, merging what were previously separate components (transceiver + external fiber segment + connector) into a single unified structure. This eliminates the need for additional external fiber segments while maintaining optical signal transmission functionality, thereby reducing the overall volume of the optical transceiver.
2Device complexity
If the end surface of the fiber connecting segment is perpendicular to the center axis, then the structure is simple, but assembly tolerance causes shifting and misalignment
Solution Approach 1:
The end surface of the fiber connecting segment is designed with an angled configuration rather than being perpendicular to the center axis. This asymmetric angular design compensates for assembly tolerances by creating a self-aligning structure where the angled surface guides proper positioning, thereby improving alignment precision without significantly increasing structural complexity.
3Adaptability or versatility
If additional fiber is configured between the positioning element and the housing, then connection flexibility is improved, but the size and complexity of the transceiver increases
Solution Approach 1:
The unnecessary additional fiber segments are extracted and removed from the transceiver structure. The invention achieves connection flexibility through the integrated fiber connecting segment that is precisely positioned within the housing, eliminating the need for extra fiber while reducing overall device complexity and size.

AI summary
An optical transceiver includes a positioning element, a fiber connecting segment, a base and a housing. The positioning element has a first positioning part. The fiber connecting segment tightly fits to the positioning element. The housing supports at least one optical transceiving element and is connected to the positioning element. The base has a second positioning part and is configured for supporting the positioning element and the fiber connecting segment. The first positioning part and the second positioning part define the position of the fiber connecting segment.
