- 33.120.10 Coaxial cables. Waveguides
Part 1-17 of EN 50289 details the test methods used to determine the cable to cable (exogenous) crosstalk between 4 pair cables used in analogue and digital communication systems. These exogenous Crosstalk effects are near end crosstalk (ExNEXT), far end crosstalk (ExFEXT), equal level far end crosstalk (ExELFEXT).
This document should be read in conjunction with EN 50289‑1‑1 , which contains essential provisions for its application. Reference is made also to EN 50289‑1‑10 in which the definitions and test methods for crosstalk is given.
The exogenous crosstalk test method is described, as well as the treatment of the results to simulate the installation condition of a disturbed cable in contact with six disturbing cables.
