WebThis paper compares the efficiency of on-off Keying (OOK) modulation formats non-return-to-zero (NRZ) and return-to-zero (RZ) in both electrical and optical chromatic dispersion … On–off keying (OOK) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a binary zero. Some more sophisticated schemes vary these durations to conve…

In a nutshell, NRZ is a modulation technique with two voltage levels to represent logic 0 and logic 1. The voltage literally does not “return to zero”; logic 0 is a negative voltage, and logic 1 is a positive voltage. PAM4 uses four voltage levels to represent 4 combinations of 2 bits logic: 11, 10, 01, and 00.
