IEC 61300-3-21:2014 is a method to measure the switching time and related performance parameters of an optical switch when the actuation energy is applied or removed to change the state of the switch. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- removal of "bounce time" from the title;
- update and alignment of definitions with IEC 60876-1;
- generalization of the detection apparatus beyond an oscilloscope.
Keywords: switching time, performance parameters of an optical switch, actuation energy
