While fiber optics are known for their high-speed capabilities, latency still affects how quickly information is transmitted between devices, servers, and users. Even small delays can impact performance, especially for applications that rely on real-time communication. The presence of latency, which refers to the time delay experienced in a network, can significantly hinder. In high-speed network construction, a common question arises: why does the user experience still feel “laggy” even after upgrading bandwidth from 10G to 100G or even 400G? In many cases, the issue is not bandwidth alone, but fiber latency. For AI clusters, High-Performance Computing (HPC), and. If latency is too high it spreads data packets over the time and can create an impression that an optical metro network is not operating at data transmission speed which was expected. As light travels through the fiber, the signal strength diminishes.
