I need the answer as soon as possible

5- An engineer has the following components available: (a) GaAlAs laser diode operating at 850 nm and capable of coupling ImW into a fiber. (b) Ten sections of cable each of which is 500 m long, as a 4-dB/km attenuation, and has connectors on both ends. (c) Connector loss of 2 dB/connector. (d) A pin photodiode receiver (Si pin). (e) An avalanche photodiode receiver (Si APD). Trama CAN Oprural ir ,Indi | Ananian Wan Suste Electrica 19. txarr wuration) Irarti Inas (1200) Si (800-900 m) Racrover sensitivity (3) EGAS APD (1550) SLAPD (800-900) 1 1000 5 10 20 50 100 200 500 Data rate (M) Using these components, the engineer wishes to construct a 5-km link operating at 20 Mb/s. if the sensitivities of the pin and APD receiver are according to the below figure, which receiver should be used if a 6-dB system operating margin is required?
