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.
