Optical fibres - Measurement methods and test procedures. Differential mode delay has-tracked-changes see BS EN 1349 andWhat is BS EN IEC 60793149 Optical fibres about? BS EN IEC 60793 is a series on optical fibres. Optical fibres are used most often as a means to transmit light between the two ends of the fibre and find wide usage in fibre optic communications. BS EN IEC 60793149 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. BS
