Design a fibre system to transmit 2 Gbits/sec (RZ) over a 5000-km path. The error rate must be 10−9 or better. There is no unique solution. Design the system in your own way. Show power and bandwidth budget calculations that include the source, fibre and detector of your choice. You may chose any component that you like. However, the parameter values for those components should be actual values sourced from any text book or online data sheet that you find. You must include these as references in your report. Remember to imagine you are working for a company and that you are trying to please your boss. Therefore, whilst you must provide some reasonable bandwidth and power budget margin you should not overdesign the system. This will make your boss angry as it will be too expensive.
