i have 33 channels from 33 decoders which i convert into RF analogue signals.
Then i convert the analogue signal into fiber optical signal by using a transmitter (opt-TX-dt fracarro).I use a tight buffer single mode optical cable from my transmitter and run it 800 mts long into an optical receiver (opt-Rx-dt fracarro) and then which is reconvert into coaxial cable . i notice that my signal reception is not as clear as before my transmitter .
Please note that my optical cable is 8 piece of 100 mts link together
