Optical fibres - Part 1-49: Measurement methods and test procedures - Differential mode delay — 57 стр.
Describes a method for characterizing the modal structure of a graded-index multimode fibre. The information is useful for assessing the bandwidth performance of a fibre when used with laser sources. Applies only to multimode, graded-index glass-core (category A1) fibres. The test method is commonly used in production and research facilities, however is not easily accomplished in the field.
