IEC 62807-1:2017

Overview

IEC 62807-1:2017, titled Hybrid telecommunication cables - Part 1: Generic specification, is an international standard published by the International Electrotechnical Commission (IEC). This standard specifies requirements for hybrid cables that combine multiple transmission media types such as optical fibres, twisted pair/quad cables, coaxial cables, and current-carrying electrical conductors within a single common outer sheath. The hybrid cable design enhances convenience and efficiency for network infrastructure and customer premises wiring by enabling simultaneous transmission of data, telecommunication, and signaling services using mixed cable elements.

This generic specification sets foundational guidelines applicable to hybrid cables designed for diverse telecommunications environments, supporting optical fibre communication, metallic twisted pairs, broadband data over coaxial units, and electrical current supply to remote equipment, while ensuring safety and performance compliance.

Key Topics

• Cable Composition: Defines hybrid cables comprising optical fibres, twisted pair/quad, coaxial, and electrical conductor elements integrated under a common sheath.
• Performance Requirements: Aligns cable element specifications with established IEC standards:
  • Optical fibres: IEC 60794 series
  • Twisted pair/quad: IEC 61156 series
  • Coaxial cables: IEC 61196 series
• Design & Construction: Emphasizes compliance with detailed IEC standards for cable elements’ structure and materials, ensuring compatibility and application-specific safety.
• Material Standards: Material properties for optical, metallic, and mixed conductor elements are required to meet specified IEC material clauses.
• Test Methods: Hybrid cable testing is to be carried out in line with referenced IEC methods for each cable element type and the detailed hybrid cable specification.
• Current-Carrying Conductors: Designed for remote equipment power supply but explicitly not intended as power mains; safety regulations apply as per sectional standards IEC 62807-2 and IEC 62807-3.

Applications

IEC 62807-1:2017 applies primarily to hybrid telecommunication cables used in:

• Communication Networks: Facilitating the transmission of data and telecommunication signals via combined fibre optics, metallic pairs, and coaxial media.
• Customer Premises Wiring: Optimizing infrastructure by reducing cable clutter and installation complexity through a single hybrid cable solution.
• Remote Equipment Power Supply: Supplying electrical current to remote devices alongside data transmission without using conductors as main power supply.
• Broadband and Signaling Services: Supporting simultaneous broadband data streams and signaling over heterogeneous media types.
• Indoor and Outdoor Installations: Basis for further detailed specifications in the IEC 62807 series that define indoor (Part 2) and outdoor (Part 3) hybrid cable specifications.

This versatility makes the hybrid cable design valuable in modern telecommunication infrastructures aiming to integrate multiple communication technologies into unified cabling systems, reducing installation time and cost.
