This article will provide a detailed perspective on 400G optical modules in three typical application scenarios: data center networks, metropolitan transport networks, and long-distance high-capacity transmission networks. Scientific research, financial modeling, and genomic computing demand high-throughput, low-latency environments. Compared to earlier 100G or 200G systems, 400G solutions offer improved spectral efficiency, greater data capacity, and enhanced scalability. In this complete guide, we will break down how 400G DWDM optics work, compare today's leading coherent standards, explain deployment architectures, and show how to choose the right 400G coherent transceiver for your DCI or metro optical network.
