Abstract
With the rapid development of information technology, the demand for long-distance data transmission continues to grow, and the technology based on optical communication has become a research hotspot due to its advantages of high bandwidth, low loss and anti-interference. This study aims to explore and optimize optical communication technology solutions suitable for long-distance transmission to meet the demands of future networks for high rate and large capacity. By combining advanced modulation technology and optical fiber amplifier design, a new multi-wavelength optical signal transmission system architecture is proposed. The architecture adopts coherence detection and digital signal processing technology, which significantly improves the transmission distance and stability of the system. The experimental results show that the proposed system can achieve relay-free transmission over 5000 km without sacrificing the performance of bit error rate, which has obvious advantages over the traditional scheme.
