DESCRIPTION

BS EN IEC 61757-3-2:2022


This standard BS EN IEC 61757-3-2:2022 Fibre optic sensors is classified in these ICS categories:
  • 33.180.20 Fibre optic interconnecting devices
  • 33.180.99 Other fibre optic equipment
This part of IEC 61757 specifies terminology, characteristic performance parameters, related test and calculation methods, and specific test equipment for interrogation units used in distributed fibre optic acoustic sensing and vibration measurement systems. This document refers to Rayleigh backscatter and phase detection method by phase-sensitive coherent optical time-domain reflectometry (ϕ-OTDR) only. Quasi-static and low frequency operation modes are not covered by this document. Generic specifications for fibre optic sensors are defined in IEC 61757.
