This part of IEC 60869 applies to fibre optic passive power control devices. These have all of the following general features: - they are passive in that they contain no optoelectronic or other transducing elements; - they have two ports for the transmission of optical power and control of the transmitted power in a fixed or variable fashion; - the ports are non-connectorized optical fibre pigtails, connectorized optical fibres or receptacles. This document establishes generic requirements for the following passive optical devices: - optical attenuator; - optical fuse; - optical power limiter. This document also provides generic information including terminology for the IEC 61753-05x series. Published IEC 61753-05x series documents are listed in Bibliography.
