IEC 60869-1:2018 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 This fifth edition cancels and replaces the fourth edition published in 2012 and constitutes a technical revision.
