Overview
IEC 61300-2-14:2012 is an international standard published by the International Electrotechnical Commission (IEC) that sets out the basic test and measurement procedures for fibre optic interconnecting devices and passive components under exposure to high optical power conditions. This third edition, a technical revision of the 2005 second edition, introduces a fundamental change in the measurement method to accommodate various environments, including limited testing resources. The standard ensures that fibre optic components and devices can reliably withstand operational optical power levels without degradation.
Key Topics
- High Optical Power Testing: Provides detailed procedures to evaluate the resilience of fibre optic interconnecting devices and passive components when subjected to high levels of optical power that may be encountered during operation.
- Test Apparatus: Specifies equipment requirements, including the optical source (often a tunable light source), optical detector (power meter), environmental chamber for temperature and humidity controls, data acquisition systems, branching devices, and temporary joints.
- Measurement Parameters: Defines critical measurement conditions such as wavelength/frequency stability, output power stability, linearity and resolution of detectors, and environmental factors (temperature, humidity, exposure time).
- Test Procedure: Covers stages from preconditioning, initial examination, conditioning under high optical power, recovery, and final examination and measurement to ensure thorough evaluation.
- Safety and Accuracy: Emphasizes the use of safety devices and precise calibration techniques to maintain test integrity and personnel safety, referencing IEC 60825-1 for laser safety classification.
- Pass/Fail Criteria: Includes recommended guidelines in Annex B for assessing component performance during exposure periods.
- Adaptability: Introduces flexible measurement methods adaptable to different test setups and resource availability, making it practical for a broad range of testing environments.
Applications
- Fibre Optic Communications: Ensures the reliability and performance of fibre optic connectors, adapters, multiplexers, and other passive devices used in networks exposed to high-power optical signals.
