TLDR
In this article, the effect of nonlinearity has been investigated with different techniques such as non-return-tozero (NRZ), return-to-zero (RZ), modified duo-binary return to zero (DRZ), and modified MDRZ modulations.Abstract:
In this paper, the effect of nonlinearity has been investigated with different techniques such as non-return-to-zero (NRZ), return-to-zero (RZ), duo-binary return-to-zero (DRZ), and modified duo-binary return-to-zero (MDRZ) modulations. We have explored the fiber nonlinearities by taking dispersion of single-mode optical fiber at 2.5 Gbps communication system with various transmission lengths; i.e., 72–132 km is evaluated with respect to the nonlinearity in fibers. The evaluation is done in terms of Q factor and BER with the 0 dBm input launched power. Along with this pre-compensation, post-compensation and symmetrical compensation techniques are also applied, and it is observed that the Q factor in symmetrical compensation is higher in comparison to the pre-compensation and post-compensation techniques. Therefore, it is examined that nonlinearity effects are less effective in symmetrical compensation instead of pre-compensation and post-compensation.read more

Comparison of Chromatic Dispersion Compensation Techniques for WDM-PON Solution
TL;DR: It is shown that CD offset has a marginal role for guaranteed optical link downstream performance and maximum length of high-speed WDM-PON system and FBG is recommended as the best solution for CD compensation in pre-compensation configuration (before SMF line) in future high speed long-reach DWDM-PONS systems.
Evaluation of SPM-Induced Optical Signal Distortions in Ultra-Dense Mixed-WDM System
TL;DR: Research revealed that 2-POLSK modulated signals are more susceptible to the impact of SPM in such ultra-dense mixed transmission mode than e.g., NRZ-DPSK signals.
