An 80km point to point link consists of a 1.5m laser diode with 10mW average output power, followed by a 60km long fibers with 0.2dB/km loss. Assume that dispersion accumulated in fibers are fully compensated and they don't induce any penalty. Receiver side consists of a 2.5Gb/s detector with 95% quantum efficiency. Assume that the load impedance of the detector is 50 Ohm and it has internal RF noise figure of 7dB. Calculate the SNR of the received signal?

Answer rating: 100% (QA)

To calculate the SignaltoNoise Ratio SNR of the received signal we need to consider the signal power ... View the full answer
