Communication cables - Specifications for test methods -- Part 1-10: Electrical test methods - Crosstalk

Part 1-10 of EN 50289 details the test methods to determine the crosstalk of cables used in analogue and digital communication systems. Crosstalk effects are near end crosstalk (NEXT), far end crosstalk (FEXT), equal level far end crosstalk (ELFEXT), attenuation to crosstalk ratio (ACR) and power sum of crosstalk (PS).
It is to be read in conjunction with Part 1-1 of EN 50289, which contains essential provisions for its application.

Overview

EN 50289-1-10:2001 specifies electrical test methods for measuring crosstalk in communication cables used in analogue and digital systems. Part 1-10 defines how to determine key crosstalk effects - NEXT, FEXT, EL-FEXT (ELFEXT), ACR and the power sum (PS) of crosstalk - and is intended to be read in conjunction with EN 50289-1-1 (general electrical test requirements).

Keywords: EN 50289-1-10:2001, crosstalk test methods, communication cables, NEXT, FEXT, ELFEXT, ACR, power sum.

Key topics and technical requirements

• Scope and definitions: Methods cover near-end crosstalk (NEXT), far-end crosstalk (FEXT), equal level far-end crosstalk (EL-FEXT = FEXT − attenuation), attenuation-to-crosstalk ratio (ACR = NEXT − attenuation) and power-sum calculations for aggregate interference.
• Test sample: Minimum cable length normally 100 m; pair/quad twisting must be preserved when terminating.
• Equipment and terminations:
  • Use analyzers or generator + receiver, with baluns between unbalanced equipment and balanced cable ports.
  • Differential termination equals the cable characteristic impedance; common-mode termination nominally 50 Ω (25–100 Ω allowed).
  • Cable screens grounded at both ends; individually screened pairs terminated as required.
• Calibration:
  • Measure insertion loss of the test set-up over the specified frequency range and save calibration data.
  • Measure and correct test-set crosstalk; corrected set-up crosstalk must be ≥10 dB better than the cable’s specified values across the frequency range.
• Measurement procedures:
  • NEXT: generator and receiver at the same end.
  • FEXT: generator and receiver at opposite ends.
  • Measure all pair-to-pair combinations at the same frequency points used for calibration.
  • Note: NEXT, FEXT and EL-FEXT can vary with direction and pair selection (localized vs systematic coupling).
• Result expression:
  • Procedures for correcting measured results to a 100 m reference length are provided.
  • Power-sum PS is calculated from individual pair crosstalk contributions.

Applications and users

EN 50289-1-10 is used by:

• Cable manufacturers for product characterization and compliance testing
• Independent test laboratories validating crosstalk performance
• Network designers and installers verifying cable links for high-speed data and voice systems
• Procurement and standards teams specifying acceptance tests for structured cabling and telecom installations

Practical benefits include consistent, repeatable crosstalk measurement, reliable ACR/ELFEXT assessment for channel planning, and a basis for multi-pair interference (power-sum) evaluation.
