Abstract :
An online method of continuously monitoring the attenuation of an optical fibre during its manufacture is described. It provides a complete attenuation/length profile of the fibre. The present system can measure an overall attenuation of 30 dB, and the results agree with corresponding offline differential measurements to better than ± 1 dB/km.
