Research on Laser Safety Grading Evaluation Method of Optical Fibre Communication Products

Abstract

For laser products, safety certification is a mandatory requirement for international market access. For the standard application of certification, it is suitable for common laser product, but has less operability for optical fibre communication products. In order to make the evaluation of laser safety classification clear, this research is accomplished based on the general requirements of international laser safety standards and the application of optical fibre communication products and its characteristics. This research brings up a comprehensive discussion on measurement geometry, laser safety classification, automatic power reduction technology and safety design requirements. This research proposes a process and method for laser safety classification judgement. It also provides two verified test methods of automatic power reduction action time and the irradiance or radiant exposure during the maximum time interval. This research can provide a useful reference for laser safety design, classification, test and laser safety level certification of optical fibre communication products.
