Abstract:
With reference to the IEC 60793-1-140 international standard of optical fibre measurement methods and test procedures in attenuation, we studied the optical fibre attenuation measurement by cut-back method using tuneable lasers source. By using a power stabilised laser source, we measured the fibre attenuation in the wavelength range from 1270 nm to 1350nm and from 1520 nm to 1620 nm using ‘cut-back’ technique. The power measurement before and after cut-back have better repeatability. Besides, the evaluation of the splicing losses before and after cut-back as well as the evaluation of effective refractive index (Neff) will improve the accuracy in calculating the fibre attenuation. Our method will improve accuracy and reduce uncertainties in the measurement and thus enable us to establish our own optical fibre spectral attenuation standard.
