Design, Simulation and Testing of the OOK NRZ Modulation Format
Z modulator was connected. The OOK-NRZ modulator was driven by a signal from the generator of pseudo-random sequences.

Z modulator was connected. The OOK-NRZ modulator was driven by a signal from the generator of pseudo-random sequences.
In the past, the optical modulation format employed in lightwave communication systems was non-return-to-zero (NRZ). At that time,
The simplest optical modulation format is On-Off Keying (OOK), which encodes data as the presence or absence of light. In digital
Two optical modulators are required to obtain this signal; one to generate NRZ duo-binary signal and the other to convert the NRZ
