"Introduction

With the rapid development of communication technology, optical communication has become one of the most important and widely used communication systems in modern society. Compared with traditional wired and wireless communication, optical communication provides higher bandwidth, lower latency, and greater security. However, the performance of optical communication systems is significantly influenced by the optical channel characteristics, such as signal attenuation, optical fiber dispersion, and noise. Therefore, accurately modeling the optical communication channel is of great significance for system design, performance evaluation, and optimization.

The research problem in this paper is to address the challenges in the modeling of optical communication channels. As optical signals are transmitted through optical fibers, they experience various impairments, including signal attenuation, dispersion, and noise. These impairments can degrade the quality of the optical signal, resulting in lower transmission capacity and reliability. Existing channel models often simplify or overlook certain aspects of the optical channel characteristics, leading to inaccurate predictions and suboptimal system design.

The main objective of this research is to develop an improved model for optical communication channels that accurately captures the characteristics of optical signal transmission. By considering the effects of signal attenuation, optical fiber dispersion, and noise, the proposed model aims to provide more accurate predictions of signal quality and enable better system performance optimization.

To achieve the research goal, this paper will conduct a comprehensive survey of existing channel modeling techniques in optical communication. Based on the analysis of their limitations and drawbacks, a novel modeling approach will be proposed and evaluated through extensive simulation experiments. The contributions of this paper lie in the development of an improved optical channel model and the demonstration of its effectiveness in improving system performance.

In conclusion, this paper aims to address the challenges in modeling optical communication channels by proposing and evaluating an improved modeling approach. By accurately capturing the characteristics of optical signal transmission, the proposed model will contribute to enhancing the performance and reliability of optical communication systems."
