A 100km optical communication link is formed using the laser diode from part a), the photoreceiver from part b) and by splicing multiple segments of multi-mode optical fibre with the characteristics shown in Table 3. Table 3: Optical Fibre Characteristics (i) Calculate the power budget for the optical link and the system margin if the received optical power is still \\( -12 \\mathrm{dBm} \\) and the excess noise in the system is equal to \\( 5.4 \\mathrm{~dB} \\). [2] (ii) What is the maximum bit rate that can be achieved with the optical communication link for both a Non-Return to Zero (NRZ) and a Return to Zero (RZ) pulse.
