Overview
IEC 61300-2-22:2007 is an international standard published by the International Electrotechnical Commission (IEC) that specifies test procedures for fibre optic interconnecting devices and passive components. This part 2-22 focuses on basic test and measurement procedures for evaluating the effects of temperature changes on fibre optic components. It aims to determine whether the devices can withstand temperature fluctuations without degradation, ensuring their reliability and performance in varying environmental conditions.
This second edition of the standard updates the initial 1995 version by refining test methods, specifically describing the test method Nb from IEC 60068-2-14 and providing an optional temperature cycle for additional performance categories.
Key Topics
