Optical fibres. Measurement methods. Microbending sensitivity Ingestion-build-109673 BS 448-2 on Dimensions of1 Scope IEC 62221 , which is a technical report, describes four methods (A, B, C and D) for the measurement of microbending sensitivity of optical fibres. These four methods are distinguished by the equipment being used for measurements and their applications: method A using an expandable drum and applies to category A1 and class B fibres; method B using a fixed diameter drum and applies to category A1 and class B fibres; method C using a plate and
