IEC 61196-5-1:2012

Overview

IEC 61196-5-1:2012 is an International Electrotechnical Commission blank detail specification for CATV trunk and distribution coaxial communication cables. It applies specifically to drop cables used in cabled television distribution networks operating between −40 °C and +65 °C and across the frequency range 5 MHz to 1 002 MHz (as described in IEC 61196-5). The document provides a pro‑forma template manufacturers use to declare construction, electrical, mechanical and environmental characteristics and to state manufacturer‑specific values or minimal requirements.

Key topics and technical requirements

• Cable scope and template: a blank detail specification layout with fields for manufacturer, product type, related IEC references and mandatory entries (use of NA/NS where appropriate).
• Cable construction parameters:
  • Inner conductor, dielectric (solid, air‑spaced, semi air‑spaced, gas‑injected cellular polymer), outer conductor (types, braid angle, coverage), sheath/jacket and optional integral messenger.
• Electrical and high‑frequency tests:
  • Characteristic impedance: 75 Ω ± 2 Ω (unless otherwise specified).
  • Return loss: IRLI ≥ 26 dB across 5 MHz–1 002 MHz (measurement uncertainty
