Organization: IEC
Publication Date: 1 June 2010
Status: active
Page Count: 48
ICS Code (Fibre optic systems in general): 33.180.01
scope:

This part of IEC 61746 provides procedures for calibrating multimode optical time domain reflectometers (OTDR). It covers OTDR measurement errors and uncertainties. The test of the laser(s) source modal condition is included as an optional measurement.

This standard does not cover correction of the OTDR response.
