An optical Fiber communication system has the following characteristics: Transmitter: 1.55 pm laser with 0 dBm output. The spectral width is =10-B, where B is the bit rate. Rise time = 0.1/B Receiver: Sensitivity = -30 dBm for the required BER. Rise time = 100 ps. Fiber: Attenuation = 0.3 dB/km. Splice loss = 0.1 dB. Dispersion = 18 ps/(nm km) at 1. 55 um. System: One fiber connector at the transmitter and one at the receiver with connector loss = 1 dB each. Minimum system margin = 10 dB. Modulation: 1 Gbit/s RZ a)What is the maximum transmission distance using the link power budget?

b) What is the maximum Transmission distance using the rise time budget?
