IEC 62807-2:2026 is an International Standard from IEC for indoor hybrid communication cables. It specifies the terms, design and construction, rated values, performance requirements, test methods, packaging, and quality assurance for cables that combine optical fibre with metallic elements and may also carry power to remote equipment inside a communication network.

What does IEC 62807-2:2026 specify?

IEC 62807-2:2026 is the sectional specification for indoor hybrid communication cables in the IEC 62807 series. It applies to networks and customer premises cabling that carry data, control and signalling over optical fibres and metallic elements such as coaxial, wire/pair/quad, or other current carrying elements.

The scope keeps current carrying elements within the communication network only. They are used to supply power to equipment in that network, not for electricity distribution, transmission, or domestic appliance supply. The standard also states that MICE classifications from ISO/IEC 11801-1 are fully considered when setting performance requirements and test methods.

The document is organized into Clauses 1 to 8, plus a bibliography:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Terms and definitions
• Clause 4 - Design and construction
• Clause 5 - Rated values and characteristics
• Clause 6 - Performance requirements and test methods
• Clause 7 - Packaging
• Clause 8 - Quality assurance

What are the key requirements of IEC 62807-2:2026?

Element-specific design and rating

IEC 62807-2:2026 requires each element in the finished cable to meet its own relevant specification before the elements are assembled into a hybrid cable. Optical fibre elements are linked to IEC 60794-2, twisted pair/quad elements to the IEC 61156 series, coaxial elements to the IEC 61196 series, and current carrying elements to the appropriate power-cable specification. In practice, a hybrid cable is not designed as one generic product - each part must already be suitable for its own function.

The standard also requires the final design to be cabled into one overall unit when it combines two or more different elements. It recommends matching operating temperature ratings across the elements, and if they differ, the lowest rating governs the hybrid cable. That matters because heating from current carrying elements must be included in the design calculation.

Rated values and characteristics

Clause 5 says the rated values depend on the elements used in the cable. The document points to values such as operating temperature range, installation conditions, fibre category, copper communication category, frequency range, operating current and voltage for current carrying elements, tensile load, bend diameter, and storage conditions. In practice, the supplier and customer need to state the values that apply to the specific cable build.

Performance testing of the finished cable

Clause 6 applies to the finished hybrid cable, not just to individual elements. Compliance is verified by selected tests, and the standard says it is not intended that every test be run on every cable. The customer and supplier agree which tests apply to the optical, coaxial, pair/quad, and current carrying parts. This makes the document a practical basis for qualification and acceptance testing.

Mechanical and environmental performance

The cable is checked for tensile, crush, impact, repeated bending, cold bend, torsion, kink, bend, and marking abrasion resistance. After the mechanical tests, the outer sheath must remain free of visible cracks, flaws, or similar damage, and the relevant elements must still meet their own performance checks. The environmental tests cover temperature cycling, flame propagation, smoke density, halogen acid gas content, and UV resistance where applicable. In practice, these tests confirm that the cable can survive installation and indoor service conditions.

Packaging and quality assurance

Clause 7 requires the cable to be supplied on reels or in coils protected for transport, with sealed ends when needed to keep out moisture. Clause 8 places responsibility on the manufacturer to establish quality assurance through quality control procedures and to ensure the product meets the document. That means the standard is not only about design, but also about repeatable production.

What terms does IEC 62807-2:2026 define?

• Hybrid cable - a cable made of at least one optical fibre element and one metallic element such as a coaxial, wire/pair/quad, or other current carrying element.
• Rated voltage - the voltage relationship used for alternating current systems, expressed in volts and used to state the intended electrical rating of the cable.
• Current carrying element - the metallic part used to supply power to equipment within the communication network.
• Coaxial element - the coaxial communication element used for electrical transmission and screened performance.
• Pair/quad element - a symmetrical copper communication element built as pairs or quads for digital communications.
• MICE classifications - the environmental classification system from ISO/IEC 11801-1 that the standard uses when setting performance requirements and test methods.

Who uses IEC 62807-2:2026?

IEC 62807-2:2026 is used by cable manufacturers, design engineers, quality managers, test laboratories, and purchasers of indoor communication cabling. It helps them specify mixed optical and metallic cable constructions, choose the right test program, and check whether a product suits indoor network and customer premises applications.

Which standards are used with IEC 62807-2:2026?

• IEC 62807-1 - gives the generic specification for hybrid telecommunication cables.
• IEC 62807-3 - covers outdoor hybrid cables in the same series.
• IEC 60794-2 - provides the indoor optical fibre cable requirements used for optical elements.
• IEC 61156 series - provides the requirements for digital communications pair/quad elements.
• IEC 61196 series - provides the requirements and test methods for coaxial communication cables.
• IEC 60227 series and IEC 62821 series - support current carrying elements, depending on the insulation and sheath type.
• IEC 63294 - provides test methods for electric cables up to and including 450/750 V.
• ISO/IEC 11801-1 - supplies the MICE classification basis used in performance selection.
• IEC 60332, IEC 60754, IEC 61034-2, and IEC 60794-1-214 - support fire, smoke, halogen acid gas, and UV testing.
• IEC 60050 series and IEC TR 61931 - provide the terminology used in the document.

What does the IEC 62807-2:2026 document contain?

IEC 62807-2:2026 contains four requirement tables: one each for optical elements, coaxial elements, pair/quad elements, and current carrying elements. Clause 6 gives the test methods for optical performance, electrical and transmission performance, mechanical robustness, and environmental behaviour. The tables and test clauses are used to build qualification plans, verify supplier claims, and define acceptance criteria for indoor hybrid cables.
