Description (English):

IEC 61196-6-3:2020 applies to coaxial communication cables described in IEC 61196-6. It specifies the requirements for 75-5 type CATV drop cables. These cables are used in CATV distribution systems, surveillance & control systems, satellite television receiving systems and as bidirectional hybrid fibre coaxes (HFC). The operating frequency is from 5 MHz to 3 000 MHz. This part of IEC 61196 is to be used in conjunction with IEC 61196-1:2005 and IEC 61196‑6:2009. It determines the layout and style with respect to the model and type. This second edition cancels and replaces the first edition, published in 2018. This edition includes the following significant technical changes with respect to the previous edition: - designation of variants including construction details, - consistent screening classes, - bending test only for flexible cables.

Abstract

Overview

IEC 61196-6-3:2020 is the International Electrotechnical Commission detail specification for 75‑5 type CATV drop coaxial cables. It applies to coaxial communication cables described in IEC 61196‑6 and sets construction, performance and test requirements for drop cables used in CATV distribution, surveillance & control systems, satellite TV receiving and bidirectional hybrid fibre‑coax (HFC) networks. The operating frequency range is 5 MHz to 3 000 MHz. This second edition (2020) replaces the 2018 edition and introduces variant designations, consistent screening classes and limits the bending test to flexible cables.

Key topics and technical requirements

Cable types and construction: 75‑5S (standard shield), 75‑5T (tri‑shield), 75‑5Q (quad‑shield) with specified inner conductor (BC or CCS), foamed PE dielectric and PE/PVC/LSZH jackets. Typical dimensions are specified (e.g., inner conductor Ø 1.02 mm; dielectric Ø 4.57 mm; outer diameters per variant).
Electrical performance:
- Nominal impedance: 75 Ω ± 3 Ω (measured at 200 MHz).
- Operating frequency: 5 MHz – 3 000 MHz.
- Return loss (uniformity of impedance): ≥ 20 dB (5–1 000 MHz), ≥ 18 dB (1 000–2 000 MHz), ≥ 16 dB (2 000–3 000 MHz).
- Attenuation: Maximum values defined in Annex B (measured at 20 °C).
- Relative propagation velocity: ~85% nominal.
Screening and EMC:
- Defined screening classes (A+, A, B, C) with transfer impedance limits (e.g., A+ ≤ 0.9 mΩ/m @5–30 MHz) and screening attenuation minima across frequency bands (measured before/after flexure).
Mechanical and environmental tests:
- Flexure/bending (IEC 61196‑1‑314), cold bend, climatic sequence, damp heat, UV ageing and thermal ageing with pass/fail limits (e.g., attenuation change ≤ 7% after climatic cycles).
- Mechanical tolerances: eccentricity, ovality, sheath thickness and tensile/elongation requirements for BC/CCS conductors.
Identification & marking: variant designation, screening class and construction details per Annex A.

Applications and who uses this standard

IEC 61196‑6‑3:2020 is used by:

Cable manufacturers for design, production and quality control of 75‑5 CATV drop cables.
Network operators and HFC system designers specifying drop cable performance for broadband CATV, satellite TV and surveillance installations.
Test laboratories and certification bodies performing electrical, mechanical and EMC testing.
Installers and procurement teams who need compliant cable specifications (material, screening, jacket type: PE/PVC/LSZH).
