BS EN 50289 is a series on communication cables. Communication cables are a type of guided transmission medium. BS EN 50289-1-17 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), an equal level of far-end crosstalk (ExELFEXT).
BS EN 50289-1-17 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 are given. The exogenous crosstalk test method is described, as well as the treatment of the results to simulate the installation condition of a disturbing cable in contact with six disturbing cables.
BS EN 50289-1-17 on communication cables is useful for:
Cables are usually known to transmit electric energy (AC/DC); however, cables in telecommunications fields are used to transmit electromagnetic waves; they are called electromagnetic waveguides. BS EN 50289-1-17 describes test methods that are carried out in accordance with IEC 61156-1:2007.
In electronics, crosstalk is any phenomenon by which a signal transmitted on one circuit or channel of a transmission creates an undesired effect in another circuit or channel.
Using BS EN 50289-1-17 you can understand 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), an equal level of far-end crosstalk (ExELFEXT).
