BS EN 60793 is a series on optical fibres. Optical fibres are flexible, transparent fibres made by drawing glass (silica) or plastic to a diameter slightly thicker than that of human hair. BS EN 60793 1 41 describes three methods for determining and measuring the modal bandwidth of multi mode optical fibres (see IEC 60793 2 10, IEC 60793 30 series and IEC 60793 40 series). The base band frequency response
