Calibration of optical time-domain reflectometers (OTDR) - Part 1: OTDR for single mode fibres

Calibration of optical time-domain reflectometers (OTDR) - Part 1: OTDR for single mode fibres

IEC 61746-1: 2009 provides procedures for calibrating single-mode optical time domain reflectometers (OTDR). It only covers OTDR measurement errors and uncertainties.

This standard does not cover correction of the OTDR response.

This first edition of IEC 61746-1 cancels and replaces the second edition of IEC 61746, published in 2005. It constitutes a technical revision.

The main technical changes are:

  • the adaptation of Clause 4,
  • the suppression of Clause 10,
  • the improvement and the addition of some definitions,
  • the change of some calculations, and
  • the change of graphical symbology to IEC/TR 61930.

Keywords: calibrating single-mode optical time domain reflectometers (OTDR)
