Optical circuit boards - Basic test and measurement procedures - Part 2: General guidance for defini...
IEC 62496-2:2017 specifies a method of defining the conditions for measurements of optical characteristics of optical circuit boards. The method comprises the use of code reference look-up tables to identify different critical aspects of the measurement environment. The values extracted from the tables are used to construct a measurement identification code, which, in itself, captures sufficient…
