Methods and systems for compensation for alien crosstalk between connectors
The present invention relates to methods and systems for minimizing alien crosstalk between connectors. Specifically, the methods and systems relate to isolation and compensation techniques for minimizing alien crosstalk between connectors for use with high-speed data cabling. A frame can be configured to receive a number of connectors. Shield structures may be positioned to isolate at least a subset of the connectors from one another. The connectors can be positioned to move at least a subset of the connectors away from alignment with a common plane. A signal compensator may be configured to adjust a data signal to compensate for alien crosstalk. The connectors are configured to efficiently and accurately propagate high-speed data signals by, among other functions, minimizing alien crosstalk.
1. A method of determining the amount of alien crosstalk on a jack, the method comprising the steps of:
transmitting a test signal to a first disturber conductive pair of a disturber jack positioned adjacent a victim jack that includes a first victim conductive pair and measuring the alien crosstalk induced on the first victim conductive pair by the first disturber conductive pair;
transmitting a test signal to a second disturber conductive pair of the disturber jack and measuring the alien crosstalk induced on the first victim conductive pair by the second disturber conductive pair; and
aggregating the measurements to determine a sum alien crosstalk on the first victim conductive pair.
2. The method of claim 1 , wherein the victim jack and the disturber jack are coupled to terminations including resistors for simulating a network connection.
3. The method of claim 1 , further comprising the steps of providing a plurality of disturber jacks adjacent the victim jack and transmitting a test signal to each of the disturber conductive pairs of each of the disturber jacks and measuring the alien crosstalk induced on the first victim conductive pair by all of the disturber conductive pairs.
4. The method of claim 3 , wherein each disturber jack includes at least four disturber conductive pairs.
5. The method of claim 1 , wherein the victim jack includes a plurality of victim conductive pairs, the method further comprising transmitting a test signal to the first and second disturber conductive pairs and measuring the alien crosstalk induced on each of the victim conductive pairs by the first and second disturber conductive pairs and aggregating the measurements to determine a sum alien crosstalk on each of the victim conductive pairs.
6. The method of claim 5 , wherein the plurality of victim conductive pairs includes at least four victim conductive pairs.
7. The method of claim 1 , further comprising the step of providing conductive elements on a circuit board on the victim jack to compensate for the alien crosstalk.
8. The method of claim 7 , wherein the conductive elements provide inductive and capacitive coupling.
