    Abstract - (Show below) - (Hide below)

    Gives procedures for calibrating multimode optical time domain reflectometers (OTDR).

    Scope - (Show below) - (Hide below)

    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.
