IEC 60869-1:1999

This part of the standard applies to fibre optic attenuators which have all of the following general features: they are passive in that they contain non optoelectronic or other transducing elements; they have two ports for the transmission of optical power, and attenuate the transmitted power in a fixed or variable fashion; the ports are optical fibres or optical fibre connectors. It establishes uniform requirements for the following: optical, mechanical and environmental properties, and measurement and test porcedures for quality assessment.

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.
