IEC 60869-1:2018 is available as \/2 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60869-1:2018 applies to fibre optic passive power control devices. These have all of the following general features: \u2013 they are passive in that they contain no optoelectronic or other transducing elements; \u2013 they have two ports for the transmission of optical power and control of the transmitted power in a fixed or variable fashion; \u2013 the ports are non-connectorized optical fibre pigtails, connectorized optical fibres or receptacles. This document establishes generic requirements for the following passive optical devices: \u2013 optical attenuator; \u2013 optical fuse; \u2013 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 This fifth edition cancels and replaces the fourth edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the terms and definitions have been reviewed; b) the requirement concerning the IEC Quality Assessment System has been reviewed; c) the clause concerning quality assessment procedures has been deleted; d) Annex G, relating to technical information on variable optical attenuators, has been added. Keywords: fibre optic passive power control devices<\/p>\n
