EVS-EN IEC 60869-1:2018

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.
