What does the term alien crosstalk refer to in networking?

The term alien crosstalk specifically refers to interference that occurs between adjacent data cables, typically in bundled networking environments where multiple cables run in close proximity to one another. This type of interference can disrupt the signals being transmitted through the cables, leading to data integrity issues and reduced performance.

Alien crosstalk is distinct from other forms of interference that might arise from devices connected to the network, poor signal strength, or electrical wiring, as those pertain to different sources and mechanisms of signal degradation. In scenarios with many cables, such as in data centers or structured cabling systems, managing alien crosstalk is crucial for maintaining reliable communication and high data throughput. Thus, interference from neighboring data cables is the most accurate definition of alien crosstalk in the context of networking.
