Calibration of optical time-domain reflectometers (OTDR) - OTDR for multimode fibres Ingestion-build-181247 Why should you use PD1 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.
