If you are comparing fiber vs Ethernet cable, the short answer is simple: fiber is the right choice for long runs, high-speed uplinks, inter-building links, and electrically noisy environments. Most wireless access points in commercial installations are powered via Power over Ethernet (PoE). For most office endpoints under 100 meters, Cat6 or Cat6A Ethernet is still the better choice because it. Choosing between fiber optic cable and Ethernet (copper) cable is critical for network performance, cost, and scalability. While both transmit data, their underlying technologies create stark differences in speed, distance, and durability. Its core function is the same as a normal AP—broadcasting Wi-Fi signals to allow wireless-capable devices to connect.
