IEC 60869-1 Ed. 4.0 b:2012

IEC 60869-1:2012 applies to fibre optic power control devices. These have all of the following general features:
- they are passive in that they contain no opto-electronic or other transducing elements;
- they have two ports for the transmission of optical power and control the transmitted power in a fixed or variable fashion;
- the ports are unconnectorized optical fibre tails or optical fibre pigtails with connectors. This standard establishes generic requirements for the following passive optical devices:
- optical attenuator;
- optical fuse;
- optical power limiter. This fourth edition cancels and replaces the third edition, published in 1999, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the terms and definitions were reconsidered;
- the requirement concerning the IEC Quality Assessment System was reconsidered;
- the clause concerning quality assessment procedures was deleted. Keywords: fibre optic power control devices
