Optical fibres - Attenuation measurement methods Ingestion-build-209418 BS 8507-2:2009 Code of practiceWhat is this standard about? This part of IEC 60793 establishes uniform requirements for measuring the attenuation of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. Four methods are described for measuring attenuation, one being that for modelling spectral attenuation: method A: cut back; method B: insertion loss; method C: backscattering; method D: modelling spectral attenuation. Methods A to C apply
