Calibration of optical time-domain reflectometers (OTDR) - Part 2: OTDR for multimode fibres (IEC 61746-2:2010); German version EN 61746-2:2011
Kalibrierung optischer Rückstreumessgeräte (OTDR) - Teil 2: OTDR für Mehrmodenfasern (IEC 61746-2:2010); Deutsche Fassung EN 61746-2:2011
Overview
This part of IEC 61746 specifies methods for the calibration of multimode optical time domain reflectometers (OTDR). It only describes OTDR measurement errors and uncertainties. The test of the laser(s) source modal condition is included as an optional measurement. The responsible Committee is K 412 "Kommunikationskabel (Kabel, Leitungen, Wellenleiter, Lichtwellenleiter, Komponenten, Zubehör und Anlagentechnik für die Nachrichten- und Informationsübertragung)" ("Communication cables (Cables, lines, waveguides, fibre optic cables, components, accessories and installation technology for telecommunications and information transmission)") of the DKE (German Commission for Electrical, Electronic and Informational Technologies) at DIN and VDE.
