All About Alien Crosstalk Measurement

Alien crosstalk is the coupling of noise from one cable link to another. This happens if one cable is surrounded by many other cables in a bundle. We identify the cables that surround a cable in a bundle as Disturbers. Cables that can suffer from noise coupling from other cables are identified as the Disturbed cable or (Victim).
This becomes more important as we increase the bandwidth requirement of cables for faster applications and the surrounding cables (Disturbers) impact the ability of the disturbed cable (Victim) to transmit data.  You might think that using shielded cables i.e. (where there is at least an outer shield) then alien crosstalk would not be a problem. However, if the shield is not terminated correctly even a shielded system can fall foul of alien crosstalk.
