Overview
IEC 61753-071-02:2020 is an international standard established by the International Electrotechnical Commission (IEC) for fibre optic interconnecting devices and passive components. Specifically, it sets the performance requirements for non-connectorized single-mode fibre optic 1 × 2 and 2 × 2 spatial switches intended for use in category C – controlled environments. This standard defines the minimum initial test and measurement requirements and the associated severities that products must meet to be classified under category C, as detailed in IEC 61753-1:2018.
This consolidated edition (including Amendment 1 of 2024) supersedes the earlier IEC 61753-071-2 published in 2014 and introduces significant technical enhancements to ensure better repeatability, durability, and harmonization with updated test conditions.
Key Topics
- Performance Requirements: IEC 61753-071-02 specifies key parameters such as switching durability, repeatability, and switching time for spatial switches.
- Test Procedures and Conditions: Detailed testing methods cover various performance aspects under controlled environmental conditions, aligning with IEC 61753-1:2018.
- Device Configurations: The standard covers non-connectorized single-mode spatial switches in:
- 1 × 2 configuration
- 2 × 2 configuration (both crossover and non-crossover types)
- Test Items Removed or Modified:
- Removal of previously required directivity performance and operational shock tests.
- Revised test conditions for high optical power to reflect contemporary operational requirements.
- Normative References: The standard references foundational IEC documents including IEC 61300 series, IEC 60793 (optical fibres), IEC 60794-2-50 (indoor cables), and IEC 60068 (environmental testing).
Applications
IEC 61753-071-02:2020 applies to fibre optic spatial switches used in controlled environments such as:
- Data Centers and Telecommunication Networks: Where high reliability and repeatability of fibre optic switching are critical.
- Precision Instrumentation and Measurement Systems: Systems requiring precise optical signal routing with minimal optical loss.
- Industrial and Laboratory Environments: Controlled settings demanding stringent performance to ensure stable optical interconnection.
This standard helps manufacturers and users ensure that spatial switch devices meet rigorous quality and performance benchmarks, leading to enhanced system dependability in fibre optic networks.
