3.2. Bit Error Rate
Measurement BER on simulator is one method how we can see fiber optic network performance besides
with power budget link. In the simulator, the measurement uses BER Analyzer by displaying the eye
diagram. Analysis method using eye diagram is a simple method but able to accurately assess from a
digital transmission system. The measurement with the eye diagram is made in the time domain and
shows the distortion effect of a wave which in its application can be seen by the oscilloscope.
Figure 5
. Results BER Analyzer from Downlink configuration.
The eye diagram in figure 5. Shows the result BER Analyzer downlink configuration with a
maximum distance of 17 Km. Obtained BER with a value of 2.99513e
-012
and Q-Factor of 6.87953. The
result states that within a trillion bits sent, there is 1 wrong bit. The signal waves shown in Figure 6.
there is interference but still visible an eye shape indicating the Signal to Noise Ratio (SNR) and the
receiver can still read the signal in this configuration. This figure is much lower than the minimum
recommended BER for fiber optic communication systems i.e.
10
. The simulation results prove that
with the fiber cable length L = 17 Km (maximum length), the network is still said to be in decent
condition.
Good results are also shown in figure 6. The upstream portion of optical fiber communication with
the same transmission distance as downstream, but the eye pattern is more clear and open. The resulting
BER is zero. This indicates that there is no error in digital transmission.
