- Advanced crosstalk management capabilities deal with both NEXT (near-end crosstalk) and FEXT (far-end crosstalk) in scenarios where multiple fiber extenders are deployed in the same apartment building.
New technology solves this problem by providing compliant-pin termination while minimizing near-end and far-end crosstalk, matching the signal integrity of SMT connectors.
This involves extracting some of the important parameters such as characteristic impedance ([z.sub.0]), time delay (td), dielectric constant (dk), near-end crosstalk ([s.sub.31]), far-end crosstalk ([s.sub.41]) and transmission coefficient ([S.sub.21]).
However, the transmission performance of xDSL is heavily influenced by various disturbances and noises in multi-pair and multi-quad metallic cables and especially by far-end crosstalk (FEXT) [3].
The theoretical results of near- and far-end crosstalk characteristics obtained by the proposed approach and the results using a commercial solver (HFSS), and the measured results are shown in Figs.

The most effective way to reduce far-end crosstalk is by using stripline, but that's another story.
The measurement setup emulates the crosstalk behavior at the receiver side so the evaluation targets far-end crosstalk (FEXT).
The crosstalk signal [x.sub.FEXT](t) is called a far-end crosstalk FEXT.
All the possible pair combinations for both alien near-end and far-end crosstalk were measured and evaluated over the frequency range up to 500 MHz.
Which is more likely, that the corners are producing the dips or far-end crosstalk is producing the dips?
The model UFX-9835 is a test instrument that generates near-end crosstalk (NEXT) and far-end crosstalk (FEXT) for production testing of DSL modems.
