The IMPATI diode in the modulator of a coded signal to transmitter accelerates а maximum speed of
2.4×10^6 m/s in 5.0micro second. This speed is from rest maintained through fiber for a The Sigle mode optical 4μs before arriving at the receiver. The Gun dio de used in demodulator at receiver decelerates the Signal to rest at the decoder for another 4micro second. (a) use graphics metted to determine the length of the path covered by the signal when passing through the ; (i) The IMPATT diode (ii) The optical Channel (ii) The Gun diode. (b) using any other method, Calculate the total length covered Path length Covered by the signal. ​
