Explain how receiver functions in fibre optic communication system.
Receiver:
The optical signal received must be first converted within digital form and in case analog output. Moreover, the analog output has to be amplified to overcome the loss when any throughout its propagation via optical fibre.
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
