Extracted text: A network operator has asked you to design a point-to-point optical link for short reach (2 km) transmission inside a data centre. The operator's primary concerns are; (i) to minimise capital expenditure (i.e. to keep deployment costs as low as possible) and (ii) to have excellent receiver sensitivity. (a) Draw a block diagram of the optical link you propose, outlining the components used and the reasons for your design choices. (b) Regarding your transmitter design choice: How will electrical information be transferred to the optical domain in your system? And what are the potential drawbacks of this technique? Please use drawings in your answer.
