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.
