IEC 60793-1-47 Ed. 3.0 en:2009 Optical fibres - Part 1-47: Measurement methods and test procedures - Macrobending loss
standard by International Electrotechnical Commission, 03/05/2009
More info
Full Description
IEC 60793-1-47:2009(E) 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 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. The main technical revision to this edition is the introduction of Annex A describing small bend radius phenomena. This standard is to be read in conjunction with IEC 60793-1-1.This publication is to be read in conjunction with IEC 60793-1-1:2008.
