100BASE-FX is a networking technology that falls under the category of Fast Ethernet. It is a standard for transmitting data at a speed of 100 megabits per second (Mbps) over optical fiber cables. The "FX" in 100BASE-FX stands for "Fiber Optic" because it utilizes optical fibers to transmit data.
100BASE-FX is commonly used in local area networks (LANs) and is particularly suitable for network connections that require longer distances than what can be achieved with copper cables. The standard specifies the use of multimode optical fiber with SC or ST connectors, allowing for reliable and high-speed data transmission.
Compared to its copper-based counterpart, 100BASE-TX, which uses twisted pair cables, 100BASE-FX provides several advantages. It can support longer cable runs, typically up to 2 kilometers, and is immune to electromagnetic interference (EMI). It is also well-suited for environments where there may be a risk of electrical hazards or where there is a need for data transmission across different buildings or floors.
