Omfang

IEC 60793-1-47:2009 establishes uniform requirements for measuring the macrobending loss of single-mode fibres (category B) at 1 550 nm or 1 625 nm, category A1 multimode fibres at 850 nm or 1 300 nm, and category A3 and A4 multimode fibres at 650 nm, 850 nm or 1 300 nm, thereby assisting in the inspection of fibres and cables for commercial purposes. The standard gives two methods for measuring macrobending sensitivity: - Method A: Fibre winding, pertains to category B single-mode fibres and category A1 multimode fibres; - 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. Keywords: inspection of fibres and cables for commercial purposes This publication is to be read in conjunction with IE C 60793-1-1:2008.
