Consider a 1550 nm laser diode with a rise time of 0.8 ns, spectral half-width of 6 nm, that launches 2 mW optical power into a 60 km long single-mode fiber with an attenuation of 0.3 dB/km. The intramodal dispersion is 3 ps/nm.km. An InGaAs APD with a -32 dBm sensitivity is used at 2.5 Gb/s (NRZ coding). A short optical jumper cable at each end of the cable with a loss of 3 dB is used to connect the fiber to the equipment rack. In addition, the connector loss at each joint between the jumper and fiber cable and jumper and equipment rack is 1 dB each. Determine the temporal response of the system components and calculate the maximum transmission rate. Discuss if the system is bandwidth limited.
