This part of IEC 60869 applies to fibre optic power control devices. These have all of the following general features: - they are passive in that they contain no opto-electronic or other transducing elements; – they have two ports for the transmission of optical power and control the transmitted power in a fixed or variable fashion; - the ports are unconnectorized optical fibre tails or optical fibre pigtails with connectors. This standard establishes generic requirements for the following passive optical devices: - optical attenuator; - optical fuse; - optical power limiter. Test and measurement procedures for the above products are described in IEC 61300-1, the IEC 61300-2 series and the 61300-3 series [1,2,3 – refers to Bibliography]
