NRZ

(Non-Return-to-Zero) A data modulation method in which the 0s and 1s are represented by different polarities, typically positive for 0 and negative for 1. See NRZI.

For the system's second channel on-off keying method and NRZ encoding is used, despite the fact, that NRZ-OOK modulation format is not well situated for high density WDM systems with a large number of transmission channels and high transmission rate and, as consequence of that, a high total transmission capacity.
The PAM-4 eye diagram comprises three eye openings instead of one and includes 12 types of transitions, whereas NRZ signals have only two.
"It is not clear what will be the right combination of symbol rate, bits per symbol, and number of carriers," she continued, asking, "Will 32-Gbaud PAM4 or 32-Gb/s NRZ be the right solution?
The company also announced Manchester and NRZ configurable protocol decoders for its oscilloscopes (Figure 3).
NRZ data transmission at rates higher than 1 Gb/s begins by merging multiple low-speed channels into one high-rate NRZ bit stream.
The portfolio features products with different modulation formats, including NRZ, negative-chirp NRZ, Duobinary and high dispersion tolerance, the company claims.
Capabilities include NRZ serial pattern triggering and protocol decode with built-in clock recovery.
The 81142A features RZ, R1, and NRZ data formats with flexible parameters for generating high-quality waveforms and eye diagram measurements.
