1 Scope
This part of IEC 60869 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.
Test and measurement procedures for the above products are described in IEC 61300‑1, the IEC 61300‑2 series and the 61300-3 series [1,2,3] 1.
