Abstract
Optical time-division multiplexing (OTDM) technology, as a critical component in the field of optical communications, can significantly enhance system capacity and transmission efficiency. In response to the rapid growth of global data traffic, traditional single-wavelength communication methods are no longer sufficient to meet current demands, making the investigation of high-performance OTDM technology essential for addressing bandwidth bottlenecks. This study focuses on exploring OTDM system design approaches based on high-speed modulation and demultiplexing, incorporating advanced signal processing algorithms and optimized configurations of optical components to achieve higher-bit-rate data transmission. By combining theoretical modeling with experimental validation, a 1Tb/s-level OTDM experimental platform was constructed, and a comprehensive evaluation of system performance was conducted. The results demonstrate superior performance in terms of bit error rate, signal-to-noise ratio, and transmission distance, while effectively reducing system complexity and cost. A key innovation of this research lies in the proposal of a novel multi-level synchronization mechanism, which significantly improves the stability and reliability of signals, providing important insights for the development of future ultra-high-speed optical communication networks. The findings not only verify the practical feasibility of OTDM technology but also lay a solid foundation for its further engineering applications.
