Professional provider of high-end integrated DWDM solutions for big data transmission

By using standard optical modules (such as CFP and QSFP28), 100G transfers within the data center are possible. Although they are well suited for transmitting 100G traffic within racks and data centers, this can become a problem when 100G traffic needs to be transmitted over long distances (for example, long connections between different data centers (for example, over 40km)). This requires a 100G DWDM optical module. Since DWDM SFP transceivers are widely used for scaling up 10G network capacity, DWDM technology is not new to the industry. In terms of functionality, the 100G DWDM is very similar to its predecessor. However, it is often used for longer distances in a 100 gigabyte network. PAM4 and Coherence are two industry-leading solutions that offer greater bandwidth and transmission distance. When comparing 100G DWDM PAM4 to a coherent optical module, it depends on what functions the network needs and benefits from. In this article, we will analyze both options to help businesses ...
