Optical circuit boards - Basic test and measurement procedures - Part 2-4: Optical transmission test for optical circuit boards without input/output fibres (IEC 62496-2-4:2013); German version EN 62496-2-4:2013

Title (German)

Optische Leiterplatten - Grundlegende Prüf- und Messverfahren - Teil 2-4: Optische Übertragungsprüfung für optische Leiterplatten ohne Eingangs-/Ausgangsfasern (IEC 62496-2-4:2013); Deutsche Fassung EN 62496-2-4:2013

Overview

This standard describes a test method for optical circuit boards using direct illumination by a light. The input ports are directly illuminated and the optical intensity from the output ports of the optical circuit board is monitored using an area image sensor. Excess optical losses are then calculated from total detected intensities of light from a sample to be measured and from a control sample. This method is used to illuminate uniformly the input port of the optical circuit board (OCB) with a larger area than the core area, obtain the radiance of an area image from the corresponding output port of the OCB using an area image sensor, and evaluate whether to pass or fail using the radiance obtained compared to that of a control sample. The advantage of this test method is that the alignment procedure between the launch fibre and the OCB is not necessary. The responsible committee is DKE/UK 412.2 "Komponenten für Kommunikationskabelanlagen" ("Components for communications cable systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
