IEC 61196-7:2021

Overview

IEC 61196-7:2021 is the 2021 (Edition 2.0) IEC sectional specification for coaxial communication cables used in Broadcast and Communications Technologies (BCT) cabling in accordance with ISO/IEC 11801-4. It covers indoor drop cables for cabled television distribution and related BCT applications operating in the frequency range 5 MHz to 6 000 MHz (6 GHz) and designed to perform between −40 °C and +70 °C. This second edition updates the 2011 version by extending the frequency range to 6 GHz, revising sheath marking and labelling, and adding an informative table of typical cable characteristics (Annex B).

Key topics and technical requirements

The standard specifies construction, identification and test requirements for coaxial indoor drop cables, including:

• Cable construction elements: inner conductor, dielectric, outer conductor/screen, filling compounds, moisture barriers, wrapping layers, sheath, metallic protection, messenger/ suspension strand and oversheath.
• Cable identification and marking: type names, variants, screening classes, sheath marking and labelling requirements to support traceability and compliance.
• Electrical tests: low-frequency/DC measurements (conductor resistance, insulation) and high-frequency/transmission tests (attenuation, characteristic impedance, return loss, phase/group delay) as referenced to IEC 61196-1 series methods.
• Environmental tests: temperature cycling, water penetration, UV stability and climatic sequences to ensure operation across specified temperatures and MICE environment classes.
• Mechanical tests: bending, tensile/pull, crush, impact and abrasion resistance to verify robustness during installation and service.
• Fire performance test methods (FFS) where applicable for indoor use.
• Informative data: Annex B provides typical cable types and preferred nominal dimensions and ratings for design guidance.

Practical applications

IEC 61196-7:2021 is intended for:

• Cabled television distribution networks (indoor drops to set-top boxes and endpoints)
• Single-tenant home BCT cabling in accordance with ISO/IEC 11801-4
• High-frequency signal distribution systems up to 6 GHz (satellite, cable TV, DOCSIS and related RF services) The standard guides manufacturers in producing compliant coaxial drop cables and helps installers, system designers and test laboratories verify performance for interoperability and regulatory acceptance.

Who uses this standard

• Cable manufacturers and product engineers
• Network designers and specifiers for residential and multi-dwelling installations
• Test laboratories and quality assurance teams
• Procurement and compliance officers in broadcast, cable and telecom sectors
• Installers and integrators specifying indoor drop cable performance
