Suppose an optical fibre cable is 6 km long, that there is a connector at each end, and there are 6 splices in the cable. The following loss data is provided: The fibre cable loss is 0.2 dB/km. Connector losses are 0.6 dB/connector. Splice losses are 0.2 dB/splice. Suppose the receiver sensitivity of the Silicon Avalanche Photo diode is -58 dBm to achieve a data rate of 50 Mbps for a bit error rate of 10!"". Suppose also that there is a second wavelength of light being used in the fibre which causes intermodulation interference of 0.15 dB/km. What must the minimum transmit power for the first wavelength? Express your answer in Watts
