Abstract
Driven by technologies such as 5G, there is an urgent demand for high-capacity, long-distance, and low-power transmission in fiber optic communication. Traditional modulation and coding techniques face bottlenecks in terms of spectrum efficiency and error correction. This article explores the engineering applications of new modulation and coding technologies, analyzes the integration of high-order coherent modulation and multidimensional multiplexing, and combines LDPC codes and machine learning to study long-distance transmission and DCI implementation paths. The provincial project verifies the advantages of new technologies, including a 60% increase in spectrum efficiency, a 25% delay in transmission distance, and a two order of magnitude reduction in bit error rate. Their joint optimization provides key support for breaking through the capacity bottleneck of fiber optic communication and developing high-speed optical networks.
