Optical fibres - Measurement methods and test procedures. Differential mode delay Ingestion-build-73073 or the testing and certificationWhat is this standard about? This part of IEC 60793 applies only to multimode, graded index glass core (category A1) fibres. The test method is commonly used in production and research facilities, but is not easily accomplished in the field. This document describes a method for characterizing the modal structure of a graded index multimode fibre. This information is useful for assessing the bandwidth performance of a fibre especially when the fibre is
