Fiber Optic Cable Speeds: Everything You Need to Know
Discover how fiber optic cable speeds can revolutionize your internet experience. Explore the future of connectivity
If your router has Fast Ethernet ports (100Mbps), it can fully handle a 100Mbps fiber connection over a wired connection without being a bottleneck. The router's theoretical Wi-Fi speed of 450Mbps refers to the maximum wireless link speed, not the actual internet speed. For wired devices, the limiting factor is the LAN/WAN port speed; a 100Mbps port will cap the throughput at 100Mbps, which matches your fiber plan .
The 450Mbps rating is based on Wi-Fi 4 (802.11n) or Wi-Fi 5 (802.11ac) standards and represents the maximum link speed under ideal conditions. In practice, distance, interference, and building materials reduce actual speeds significantly. Users often experience 70–90Mbps on Wi-Fi, which is still sufficient for a 100Mbps fiber connection, but may not fully utilize the router's theoretical maximum .
A 450Mbps router is adequate for a 100Mbps fiber connection, especially for wired devices. Wireless speeds may vary, but in most home environments, the router can deliver close to the full 100Mbps. If you plan to upgrade to higher-speed fiber or want better Wi-Fi coverage and efficiency, consider a modern router with Gigabit ports and Wi-Fi 6/6E support.
