High Density Transceiver Connector With Segmented Copper Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current QSFP and SFP transceiver connectors have limited data throughput due to the number of copper contacts, which restricts the maximum data capacity and is not easily scalable without modifying the form factor, affecting compatibility and efficiency in networking switches and cables.
Innovation Solution
The design introduces additional half-length and full-length copper contacts in a high-density transceiver connector, maintaining the same form factor as low-density connectors, and includes conductive elements to connect these contacts, ensuring backward compatibility and increased data throughput by aligning them with network switch and cable contacts, while preventing crosstalk through recessed contacts and non-conductive caps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional copper contacts are added to increase data throughput, then data capacity is improved, but connector complexity and manufacturing difficulty worsen
Solution Approach 1:
The connector is divided into multiple contact sections with different lengths (full-length contacts and half-length contacts). This segmentation allows the connector to provide multiple data pathways while maintaining a manageable structural organization, resolving the contradiction between increased data throughput and connector complexity.
Solution Approach 2:
The patent utilizes the length dimension of contacts to create density variations. By having full-length contacts extend across the entire connector housing and half-length contacts extend only partially, the design increases data capacity without adding more contacts in the traditional sense, thus improving throughput while controlling complexity.
2Productivity
If additional copper contacts are added to increase data capacity, then data throughput is improved, but manufacturing precision requirements worsen
Solution Approach 1:
By segmenting contacts into full-length and half-length types with distinct functional roles, the manufacturing process can apply different precision requirements to different contact sections. Full-length contacts provide structural stability and primary connectivity, while half-length contacts add capacity with relaxed alignment tolerances, thus improving data capacity while managing manufacturing precision requirements.
3Productivity
If contact density is increased to double data capacity, then data throughput is improved, but risk of crosstalk and interference worsens
Solution Approach 1:
The segmentation of contacts into full-length and half-length sections creates natural electrical isolation zones. This physical segmentation reduces electromagnetic coupling between adjacent contacts, thereby minimizing crosstalk while maintaining high contact density for doubled data capacity.
Solution Approach 2:
Different contact sections have different lengths and positions, creating local variations in electrical characteristics. This allows optimization of each contact's performance and reduces uniform crosstalk across all contacts, as each contact operates in its own localized electrical environment.
