Comparison of the experimental bend losses (red circles: mean with s.d., n = 10; red line only to guide the eye) of fibre 1143 for three wire diameters dw with models incorporating different loss mechanisms. Pink line: model incorporating only Fresnel losses; green line: model incorporating Fresnel losses and core absorption; brown line: model incorporating Fresnel losses and core and cladding absorption; blue line: model incorporating all previous mechanisms plus the scattering at the core-cladding interface; black line: complete model incorporating all 5 loss mechanisms.
