Electrical Connector Asymmetric Interconnection Paths Crosstalk Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors used in telecommunications systems face performance issues due to near-end crosstalk (NEXT) loss and return loss, with existing techniques providing limited improvement by relying on single interconnection paths and compensation methods.
Innovation Solution
The electrical connector splits signal current into multiple interconnection paths with asymmetric configurations, utilizing conductors and traces with non-ohmic plates and crossover techniques to provide compensation stages, reducing crosstalk and improving return loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single interconnection path is used with compensation stages, then the connector provides some level of crosstalk compensation, but the electrical performance improvement is limited
Solution Approach 1:
The patent divides the single interconnection path into multiple parallel interconnection paths (first and second paths). Each path carries a portion of the signal current, allowing independent optimization of each path for crosstalk compensation. This segmentation enables better electrical performance by distributing the compensation function across multiple paths rather than relying on a single path with limited compensation capability.
2Object-affected harmful factors
If compensation is provided along a single interconnection path, then some crosstalk reduction is achieved, but the compensation effect is insufficient
Solution Approach 1:
The patent combines multiple interconnection paths (first and second paths) to work together in providing crosstalk compensation. Each path contributes to the overall compensation effect, and their combined action achieves superior crosstalk reduction compared to a single path. The merging of multiple paths allows the system to leverage the compensating effects from both paths simultaneously, enhancing the overall signal transmission quality.
3Power
If signal current is transmitted through a single path, then the connector structure is simpler, but the power handling and signal transmission capability are limited
Solution Approach 1:
The patent segments the signal current transmission into multiple parallel paths, with each path carrying a portion of the total current. This current distribution across multiple paths increases the overall power handling capability of the connector while maintaining a manageable structural complexity. Each path is designed to handle a specific portion of the signal, and their combined capacity exceeds what a single path could achieve.

AI summary
An electrical connector including an array of conductors having at least one differential pair of conductors that extends between a mating end and a loading end of a housing. The conductors are configured to engage a selected mating contact of a mating connector at a mating interface. The electrical connector also includes a plurality of traces that extend between the mating and loading ends. Each trace is electrically connected to a corresponding conductor proximate to the mating end and/or the loading end. Also, the electrical connector includes a first interconnection, path formed by the conductors that extends from the mating interface to the loading end and a second interconnection path formed by the traces that extends from the mating interface to the loading end. The differential pair transmits current that is split, between the first and second interconnection paths where at least one interconnection path provides compensation.
