Optical fibres - Measurement methods and test procedures. Macrobending loss Ingestion-build-52208 design methods1 Scope This part of IEC 60793 establishes uniform requirements for measuring the macrobending loss of single mode fibres (class 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. This document gives two methods for measuring macrobending sensitivity: Method A Fibre
