In telecommunication, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented by some other significant condition, usually a negative voltage, with no other neutral or rest condition. For a given data signaling rate, i.e., bit rate, the NRZ code requires only half the baseband bandwidth required by the Manchester code (the passband bandwidth is the same). The pulses i… WebOOK modulation can be used both NRZ and RZ pulse formats (Fig. 1). In NRZ-OOK, the final duration of the optical pulse duration is the same as the symbol ”T”.
