 # Basic example of usage
-In this section, a basic illustrative example of the usage of the OptiCommPy package is presented. A schematic for the transmission system being simulated is shown in Fig.~\ref{fig:basic-IMDD}. It consists of a 10~Gb/s NRZ OOK transmission over 100~km of optical fiber with direct detection at the receiver assuming a photodiode with 10 GHz of bandwidth. The fiber channel is modeled as a linear propagation medium exhibiting loss and chromatic dispersion. All the simulation parameters are listed in Table~\ref{tab:simparam}.
