Ten multimode glass fibers (n1 = 1.48, n2 = 1.45) are spliced together. Each fiber is 2 km long and has a loss rate 2-dB/km. Each splice adds 1 dB of loss. If the output power of the source is 7 dBm and radiates uniformly in a 60 degree half cone, how much power is delivered to the end of this combined fiber?
