What is Attenuation Measurement in Optical Fiber about?

Using two optical fiber cables (OFC) of lengths 1.5m and 3m, the experiment determines the attenuation in the cables and the attenuation coefficient. Current measurements are taken at the output ends of each cable connected to a laser and optical sensor. The attenuation is calculated as 3.46 dB based on the current readings. The attenuation coefficient is then determined to be 2306 dB/km based on the measured attenuation and length difference between the cables.
