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