Overview
IEC 61073-1:2009 - "Fibre optic interconnecting devices and passive components - Mechanical splices and fusion splice protectors for optical fibres and cables - Part 1: Generic specification" is the fourth edition of the IEC generic specification for fibre optic splice hardware. It defines requirements and quality assessment procedures for mechanical splices and fusion splice protectors used with optical fibres and cables. This standard covers documentation, classification, design/construction, performance, identification, packaging, storage and safety for splice hardware. It does not include detailed test and measurement procedures (see IEC 61300 series).
Key topics and technical requirements
- Scope and classification: Hardware is classified by type, arrangement, style, variant, assessment level, and normative reference extensions (example types: V-groove, capillary, precision-rod, shape-memory alloy mechanical splices; fusion splice protection).
- Documentation and specification system: Requirements for symbols, drawings, performance statements, measurements, test reports and instructions for use.
- Design and construction: Materials selection and workmanship expectations to ensure reliable splice protection and handling.
- Performance and quality assessment: Generic performance requirements and quality assessment procedures that manufacturers and assessors must follow (the standard specifies assessment processes rather than specific test methods).
- Identification, marking and packaging: Rules for variant identification numbers, component/package marking, and packaging to preserve product integrity.
- Storage and safety: Storage condition guidance and safety considerations (e.g., laser safety cross-references).
- Standards interlinking: Cross-references to related IEC and ISO documents governing terminology, test methods and drawing/tolerancing conventions.
Notable editorial changes in this edition include reconsidered terms/definitions, added “style” classification, removal of an environmental category from classification, and a revised standardization/interlink structure.
Applications and who uses it
IEC 61073-1 is practical for:
- Manufacturers of mechanical splices, fusion splice protectors and splice kits - for product specification and quality systems.
- Quality and compliance teams - to implement quality assessment procedures for fibre optic splice hardware.
- Procurement and OEMs - to specify acceptance and documentation requirements for purchased splice hardware.
- Network designers and installers - to understand product classes, documentation expectations and safe handling/packaging guidance.
- Test laboratories and certification bodies - to align assessment approaches and reference complementary test standards.
Keywords: fibre optic splice hardware, quality assessment, mechanical splices, fusion splice protection, splice protector, V-groove.
