Full title and description

St IEC 62706-2019 — Optical fiber cables — Indoor distribution cables — General specifications (Singapore Technical Reference to IEC 62706:2014/AMD1:2017 consolidated as 2019 technical publication). This document provides technical specifications and requirements for indoor optical fiber distribution cables used in building backbone and horizontal cabling, addressing construction, performance, testing and marking to ensure safe and reliable installation and operation within indoor environments.

Abstract

This Singapore Technical (St) publication adopts the IEC 62706 series requirements for indoor distribution optical fiber cables. It consolidates the base IEC standard and subsequent amendment(s) into a 2019 technical publication for local application. The standard specifies cable types, mechanical and environmental performance criteria, fire and smoke characteristics for indoor use, test methods, and marking/identification requirements to support consistent procurement, installation and compliance with safety regulations.

General information

• Status: National adoption (Singapore Technical publication) of IEC standard, published as St IEC 62706-2019
• Publication date: 2019
• Publisher: Singapore Standards Council / Enterprise Singapore (technical adoption of IEC)
• ICS / categories: 33.180.01 (Optical fibres and cables); 33.120 (Communication cables)
• Edition / version: 2019 edition (adoption of IEC 62706 and consolidated amendment)
• Number of pages: Typically 30–60 pages depending on national formatting (IEC 62706 core documents are moderate length); actual page count in the St publication may vary

Scope

The standard applies to indoor optical fibre distribution cables intended for installation in buildings and similar structures. It covers types of indoor distribution cables (including tight-buffered, ribbon and breakout constructions), requirements for mechanical performance (tensile strength, bending, crush), environmental performance (temperature, humidity), optical performance (attenuation, bandwidth where applicable), and fire/smoke characteristics required for indoor use. It also defines test methods, quality and marking requirements to ensure traceability and correct identification of cable type, fibre count and performance class.

Key topics and requirements

• Classification of indoor distribution cable constructions (tight-buffered, breakout, indoor/outdoor hybrid).
• Mechanical performance: tensile strength, elongation, impact, bending and crush resistance tests.
• Environmental performance: temperature range for storage, installation and operation; humidity and water penetration criteria.
• Optical performance: attenuation limits, mode field diameter and bandwidth parameters for specific fibre types.
• Fire and safety characteristics: flame propagation, smoke generation and acidity/halogen content requirements for indoor use.
• Test methods and sampling procedures aligned to IEC test standards to verify compliance.
• Marking, labelling and documentation: fibre count, fibre type, manufacturing identification and performance class.
• Recommendations for installation practices and compatibility with indoor cable management systems.

Typical use and users

Used by cable manufacturers, specifiers, building services engineers, telecom contractors, systems integrators and procurement teams to specify and verify indoor optical fibre distribution cables for commercial, institutional and residential buildings. Also referenced by testing laboratories and regulatory authorities for product conformity and safety assessments.

Related standards

Commonly used alongside other IEC and international standards for optical fibres and cabling, such as IEC 60794 (optical fibre cables — generic specifications), IEC 60332 series (flame propagation tests), IEC 60754 (halogen acidity and conductivity), EN 50575/CPR for reaction to fire in Europe (where applicable), and local wiring/building codes governing fire safety and installation practices.
