Description of NRZ Time Domain and Frequency Domain Characteristics in Fiber Optic Systems

This document provides a comprehensive description of the time domain and frequency domain characteristics of NRZ (Non-Return-to-Zero) signals in fiber optic systems. Fiber optic systems play a crucial role in information transmission due to their ability to efficiently transmit large volumes of data. NRZ signaling is a commonly used signal type in fiber optic communications, making the understanding of its time domain characteristics (such as pulse shape and timing requirements) and frequency domain properties (including spectral efficiency and bandwidth requirements) essential for comprehending fiber optic system operations. From a code implementation perspective, NRZ modulation typically involves maintaining a constant voltage level throughout the bit duration, which can be implemented using digital signal processing techniques with functions like pulse shaping and clock synchronization. If you are interested in fiber optic technology, this document is definitely worth examining. Beyond the detailed characteristics of NRZ signals, it also contains valuable information about fiber optic systems, including their historical development, practical applications, and future directions in optical communication technology.
