Title:
REDUCING FAR-END CROSSTALK IN ELECTRICAL CONNECTORS
Document Type and Number:
WIPO Patent Application WO/2010/085376
Kind Code:
A3
Abstract:
The present invention involves connectors for reducing Far-End Crosstalk (FEXT) through the use of novel polarity swapping to negate the cumulative effect of FEXT. Skew adjustment is used to improve the FEXT cancellation from polarity swapping. The polarity reversal location or locations among FEXT sources are optimized to achieve maximum FEXT cancellation. The novelty polarity swapping technique can be applied to a wide variety of connectors, such as mezzanine connectors, backplane connectors, and any other connectors that can benefit from FEXT reduction.
