Optical Line Terminal NRZ
This article compares RZ (Return-to-Zero) and NRZ (Non-Return-to-Zero) line coding techniques, highlighting the differences between their pulse shapes. These methods are commonly used in digital communication and optical Duobinary transmission systems. NEC has developed a DWDM technology with a channel spacing of 25 GHz (0. 2 nm) that makes i possible to multi-plex up to 132 optical signals at 10 Gbps in the 28 nm optical amplification band. NRZ encoding is a line coding. An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. To achieve a good level of bit-error- rate (BER) as well as to enable larger repeater spacing and larger signal-to-noise ratio (SNR) in this type of fiber, it is very. acteristics and limitations of the dispersion and the fiber attenuation, nonlinear effects and the number of amplifying sections. In the publication are presented and compared simulation results of realized model in transmitting RZ and NRZ coded signals in 10Gbps optic l line with optical.
