Optical fibres - Measurement methods and test procedures. Bandwidth Ingestion-build-202139 The symbols shown in this1 Scope This part of IEC 60793 describes three methods for determining and measuring the modal bandwidth of multimode optical fibres (see IEC 60793210, IEC 6079330 series and IEC 6079340 series). The baseband frequency response is directly measured in the frequency domain by determining the fibre response to a sinusoidaly modulated light source. The baseband response can also be measured by observing the broadening of a narrow pulse of light. The
