Description (English):

IEC 61156-6:2020 describes the cables intended primarily for working area wiring as defined in ISO/IEC 11801 (all parts). It covers cable designs comprising individually screened, common screened and unscreened pairs or quads. The transmission characteristics and the frequency range of the cables are specified at 20 °C. These cables can be used for various communication channels which use as many as four pairs simultaneously. In this sense, this document provides the cable characteristics required by system developers to evaluate new systems. This fourth edition cancels and replaces the third edition published in 2010 and Amendment 1:2012. It includes the following significant technical changes with respect to the previous edition: - additional balance levels with respect to MICE implementation by certain cabling specifications; - reference to current standards and technical reports with respect to measurement techniques and remote powering

Abstract

Overview - IEC 61156-6:2020 (Work area wiring, up to 1 000 MHz)

IEC 61156-6:2020 is the fourth edition sectional specification for multicore and symmetrical pair/quad cables intended primarily for work area wiring as defined in ISO/IEC 11801. It covers symmetrical pair and quad cable designs (individually screened, common screened and unscreened) with transmission characteristics specified up to 1 000 MHz at 20 °C. This edition updates balance levels for MICE environments and adds references for modern measurement techniques and remote powering (PoE) considerations.

Key topics and technical requirements

Cable types and construction
- Individually screened pairs, common screened pairs/quads, and unscreened options for work area use.
- Conductor, insulation, sheath and identification requirements.
Electrical and transmission characteristics
- Attenuation, impedance, return loss, velocity of propagation, phase delay and delay skew.
- Pair balance parameters and additional balance levels for different MICE (Mechanical, Internal, Climatic, Electromagnetic) conditions.
Crosstalk and interference
- Near-end crosstalk (NEXT), power-sum NEXT, attenuation-to-crosstalk ratios (PS ACR-F), and alien (exogenous) crosstalk metrics (ANEXT, AACR-F).
- Transfer impedance and coupling attenuation limits for screened constructions.
Mechanical, environmental and safety tests
- Dimensional, tensile, bending, crush, impact, thermal ageing, cold bend, damp heat, flame propagation, smoke, halogen and toxic gas emissions.
Measurement and test references
- Normative references to current measurement techniques and test methods, enabling consistent lab evaluation.

Practical applications and who uses this standard

Cable manufacturers - design and certify pair/quad cables for work area deployments up to 1 000 MHz.
System developers and network designers - evaluate cable characteristics required for high-speed digital channels using up to four pairs simultaneously.
Cabling specifiers and consultants - select appropriate screened/unscreened cables for office and enterprise work areas, considering MICE conditions and remote powering (PoE).
Test laboratories and installers - verify compliance for electrical, mechanical and environmental performance; use specified test procedures to qualify products on acceptance.
Standards writers and procurement teams - reference sectional specification to define procurement and acceptance criteria for structured cabling projects.
