Full title and description

STB BS EN IEC 60794-3-70-2021 — Optical fibre cables — Part 3-70: Outdoor cables — Family specification for outdoor optical fibre cables for rapid/multiple deployment. This document is the 2021 (second) edition of the family specification describing construction, minimum performance and required mechanical and environmental tests for rugged outdoor optical-fibre cables intended for rapid or multiple deployment (temporary links, broadcast, emergency, tactical and similar uses).

Abstract

This standard defines a family specification and minimum type requirements for outdoor rapid/multiple deployment optical-fibre cables, and lists applicable mechanical and environmental test methods (tensile, abrasion, crush, impact, repeated bending, torsion, flexing, kink, bend, bending under tension, coiling/uncoiling, temperature cycling, water penetration, ageing, UV resistance, external freezing, ribbon/tube handling tests). It also includes a blank detail specification template to support procurement and type approval.

Scope

Specifies family-level requirements for outdoor optical-fibre cables designed for rugged, terrestrial rapid or multiple deployment. The standard covers recommended constructions, acceptable optical fibre categories, secondary coating and outer sheath performance, a matrix of mandatory/applicable mechanical and environmental tests, and methods for verifying deployability and reusability. It is intended to be read with related IEC 60794‑1 and IEC 60794‑3 parts and used as a basis for detail specifications and procurement.

Key topics and requirements

• Family specification approach: blank detail-spec template and minimum requirements to support type approval and procurement.
• Mechanical performance tests: tensile, abrasion, crush, impact, repeated bending, torsion, flexing, kink, bend, bending under tension, multiple coiling/uncoiling cycles.
• Environmental tests: temperature cycling, external freezing, water penetration, ageing, UV resistance and related exposure tests.
• Handling and reuse checks: ribbon strippability, fibre ribbon separability, tube kinking and other special handling tests relevant to frequent deployment or temporary installations.
• Alignment with fibre classifications and cabled fibre performance categories (updates referencing IEC 60793 series and ISO/IEC 11801‑1 alignment).

Typical use and users

Used by cable designers and manufacturers, test laboratories, certification bodies, procurement teams, broadcast/mobile production engineers, emergency and military procurement and field teams, system integrators and maintenance crews who require rugged, temporary or reusable outdoor optical links. The standard guides design choices, acceptance testing and procurement for rapid/multiple deployment applications.

Related standards

Commonly used together with IEC 60794‑1‑1 and IEC 60794‑1‑2 (general and test-method parts), IEC 60794‑3 (other outdoor cable parts) and referenced fibre standards such as IEC 60793‑2‑10 / IEC 60793‑2‑50; bibliographical and normative references also include ISO/IEC 11801‑1 and other IEC 60794 family parts. National adoptions (EN/BS/STB/etc.) mirror the international text.

FAQ

Q: What is this standard?

A: It is IEC 60794‑3‑70:2021 — a family specification for outdoor optical‑fibre cables intended for rapid or multiple deployment, adopted as EN/BS national versions in 2021.

Q: What does it cover?

A: It defines construction guidance, minimum requirements and a set of mechanical and environmental tests (tensile, abrasion, crush, impact, bending, torsion, UV, water penetration, temperature cycling, etc.), plus a blank detail specification template for procurement and type approval of deployable outdoor cables.

Q: Who typically uses it?

A: Cable manufacturers and designers, test laboratories and certification bodies, telecommunications and broadcast engineers, emergency/military procurement and field teams, and system integrators concerned with temporary or frequently moved outdoor fibre links.

Q: Is it current or superseded?

A: The 2021 publication is the second edition and cancels/replaces the 2016 first edition; it is the current IEC edition (check your national adoption registry for the exact national publication date).

Q: Is it part of a series?

A: Yes — it is one part of the IEC 60794 series (optical‑fibre cables). It should be used in conjunction with IEC 60794‑1 parts (general and test methods) and other applicable 60794 parts and fibre classification standards (IEC 60793 series).

Q: What are the key keywords?

A: Rapid deployment, outdoor optical‑fibre cable, ruggedised cable, mechanical tests, environmental tests, family specification, type approval.
