IEC 62807-3:2023

Overview

IEC 62807-3:2023 - "Hybrid telecommunication cables - Part 3: Outdoor hybrid cables - Sectional specification" is the IEC sectional standard that defines requirements for outdoor hybrid communication cables. It covers terminology, design and construction, rated values and characteristics, performance requirements and test methods, packaging and quality assurance for hybrid cables that combine optical fibre elements with metallic elements (coaxial, wire/pair/quad and optional current-carrying elements).

These outdoor hybrid cables are intended for networks and customer premises cabling transmitting data, telecommunication, instrumentation, control and signalling services. The standard explicitly restricts current-carrying elements to supplying power to network equipment only (not for general electricity distribution or domestic appliances). IEC 62807-3 is aligned with MICE classifications in ISO/IEC 11801-1.

Key topics and requirements

• Terms, definitions and symbols - consistent vocabulary for hybrid cable components and tests.
• Design and construction - cable architecture combining optical fibre elements with coaxial, pair/quad and optional power conductors.
• Rated values and characteristics - electrical ratings, mechanical limits and environmental ratings for outdoor use.
• Optical performance - requirements and test methods for cabled optical fibres (referenced to IEC 60793 and IEC 60794 series).
• Electrical/transmission performance
  • Coaxial element: characteristic impedance, attenuation, return loss and screening tests.
  • Pair/quad element: transmission parameters and crosstalk.
  • Current-carrying element: rated voltage and insulation requirements for powering network devices.
  • Crosstalk between elements: limits and measurement methods.
• Mechanical tests - tensile, crush, impact, repeated bending, torsion, bend and abrasion per referenced methods.
• Environmental tests - temperature cycling, water penetration, compound flow and UV resistance.
• Packaging and quality assurance - delivery, marking and production QA procedures.

Practical applications and users

• Use cases: outdoor access networks, hybrid fiber-coax installations, remote instrumentation and control links, and deployments where optical and metallic transmission plus limited power feeding are needed in one cable.
• Who uses this standard: cable manufacturers, network designers and engineers, specifiers and procurement teams, testing laboratories, certification bodies, and installers needing to specify or verify outdoor hybrid cable performance.
