IEC 60869-1-2018 pdf download.Fibre optic interconnecting devices and passive components – Fibre optic passive power control devices – Part 1: Generic specification (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 61 753-05x series. Published IEC 61 753-05x series documents are listed in Bibliography.

3.1 Component terms
3.1 .1 fibre optic passive power control device
passive optical device (component) which controls a transmittance with a designed wavelength-independent transfer coefficient
Note 1 to entry: The transfer coefficient may be controlled for all intensity of input power or for input power over athreshold power.
3.1 .2 optical attenuator
passive optical device (component), which produces a wavelength-independent controlledsignal attenuation in an optical fibre transmission line
Note 1 to entry: An attenuator is intended to be wavelength independent.
3.1 .3 fixed optical attenuator
optical attenuator in which attenuation is constant.IEC 60869-1 pdf download.
