IEC 60794-2-10:2023

Overview - IEC 60794-2-10:2023 (Indoor optical fibre cables)

IEC 60794-2-10:2023 is the third edition family specification for simplex and duplex indoor optical fibre cables. It defines construction, identification, dimensional and test requirements for indoor fibre cables (excluding terminated assemblies covered by IEC 60794-2-50). This edition updates normative references and aligns A1/B1 fibre category and sub‑category designations, and is intended to be used together with the general IEC 60794‑1 and IEC 60794‑2 documents.

Key technical topics and requirements

The standard covers practical and test-related aspects of indoor optical fibre cable design and verification, including:

• Cable construction components: optical fibres and primary coating, buffers, ruggedised fibres, slotted cores, tubes, stranded loose tubes, ribbon structures, strength and anti‑buckling members, ripcords, sheaths, marking and identification.
• Dimensions for fibres and buffered components (see clause on dimensions).
• Mechanical tests: tensile performance, crush, impact, bend, repeated bending, bending under tension, bending at low temperature, flexing, torsion and kink tests.
• Environmental tests: temperature cycling and related methods.
• Transmission requirements for single‑mode and multimode fibres, addressing applicable A1/B1/B6 fibre categories and sub‑categories.
• Fire performance expectations for indoor applications.
• Family specification format: blank detail specification and example constructions (Annex B and Annex A) to simplify procurement and interchangeability.
• Additional industrial requirements: optional MICE environmental classification requirements for cables installed in industrial environments (see Clause B.2).

Practical applications and who uses this standard

IEC 60794-2-10:2023 is used by:

• Cable manufacturers designing and certifying simplex and duplex indoor optical cables.
• Test laboratories conducting mechanical, environmental and transmission testing to verify compliance.
• Specification writers and procurement teams who need a family specification template for indoor cable product lines.
• Network designers and installers selecting cable types for building, campus and other indoor applications.
• Compliance and quality teams ensuring products meet internationally harmonized indoor cable requirements.

Practical benefits include consistency in construction and testing, clearer procurement specifications, and easier interoperability across indoor optical cable product families.
