Does bending fiber optic cable affect the audio signal?
You can bend fiber optic cable around a variety of widths. You can then measure the frequency and amplitude loss of each cable using a scopemeter. Compare and chart the results of your measurements to determine if a tighter bend in the wire results in a greater loss of frequency. Is copper or fiber optic cable more affected by heat? For this experiment you will need equal lengths of copper and fiber optic cable connected to an audio system. Connect each system to a scopemeter. Using a temperature-controlled heat gun and a thermometer increase the temperature of each cable in 5-degree increments until you begin to see decreases in the frequency and amplitude of the signal. Time the process using a stopwatch and chart your results to determine if copper or fiber optic cable is more quickly affected by temperature increases. Effect of the length of copper or fiber optic cable on sound production For this experiment you will need 10-foot, 20-foot and 60-foot lengths of copper and fiber opt
