The standard gives two methods for measuring macrobending sensitivity: &#8211; Method A: Fibre winding, pertains to category B single-mode fibres and category A1 multimode fibres; &#8211; Method B: Quarter circle bends, pertains to category A3 and A4 multimode fibres. For both of these methods, the optical power is measured using either the power monitoring or the cut-back technique. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision. The main change is: Introduction of the Annex A describing small bend radius phenomena.
