While fiber optics are known for their high-speed capabilities, latency still affects how quickly information is transmitted between devices, servers, and users. Explore key factors like FEC and propagation delay, and find the best optimization strategies for AI and HPC networks. Understanding Fiber Optic Latency: Why Do High-Speed Networks Still Lag? What Determines Fiber Optic Latency? In. Fiber optic latency plays a vital role in determining how fast and efficiently data moves across a network. High latency creates noticeable issues such as lagging video calls, buffering during streaming, and delays in data retrieval. The presence of latency, which refers to the time delay experienced in a network, can significantly hinder. Latency in optical networks isn't just a technical metric; it's a physical reality. In a fiber optic network, many factors contribute to.
