Optical fibres - Measurement methods and test procedures. Macrobending loss Ingestion-build-132972 Pipes used for test assembliesBS EN 60793 1 47: 2009 Optical fibres. Measurement methods and test procedures. Macrobending loss BS EN 60793 1 47 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.
