One thing I can tell is that has a fiber link in the loop and another after leaving him, that’s not good, that’s why I left only the link of the loop, because it has a line amplifier to compensate for attenuation of this fiber, these results of error rates (BER) are strangers, because it has back that they are with values 0 and the other ja is any value very strange that. Is to decrease and not having a sudden change like this and then again some results again, so I just loop fiber with 100 miles and the amplifier compensating all its attenuation, i.e. with a gain of 100 * 0.2 = 20dB. To be able to be made a graph of BER BER OSNR and m a x number of laps in the loop. How can I improve the conditions of this signal and transmit again to improve the error rate on the first lap and so in the other she if the compiler of a better way?
