Fibre optic transmission line of unknown length L has an attenuation coefficient of 0.04 km-1. When a transmitter producing 1 W of power was connected to the transmission line using a connector causing a 10% power loss, the receiver at the transmission end recorded power of 2 uW. Find the actual length L of the transmission line. Select one: O a. 325 km O b. ~651 km O c. -434 km O d. ~260 km
