标题级别1：Which Type of Cabling do Ethernet 100BASEFX Networks Use?
标题级别2：介绍
Ethernet 100BASEFX networks rely on a specific type of cabling to transmit data between devices. This article aims to explore the cabling requirements for these networks and provide a detailed explanation of the supported cabling options.
标题级别2：Fiber Optic Cabling
Ethernet 100BASEFX networks primarily utilize fiber optic cabling for their data transmission. Fiber optic cables consist of thin strands of glass or plastic fibers that carry data in the form of light pulses. This type of cabling offers numerous advantages, such as high bandwidth capabilities, immunity to electromagnetic interference, and longer transmission distances compared to other types of cabling.
标题级别3：Single-Mode Fiber
One option for the fiber optic cabling used in Ethernet 100BASEFX networks is single-mode fiber. Single-mode fiber cables have a small core diameter, usually around 9 microns, which enables them to transmit data over long distances without significant loss. This makes them ideal for applications that require data transmission over several kilometers, such as in large enterprises or data centers.
标题级别3：Multi-Mode Fiber
Another option for fiber optic cabling in Ethernet 100BASEFX networks is multi-mode fiber. Multi-mode fiber cables have a larger core diameter, typically 50 or 62.5 microns, which supports shorter transmission distances compared to single-mode fiber. They are commonly used in local area networks (LANs) and shorter-range applications where distances are limited, such as within a building or campus.
标题级别2：Copper Cabling
Although fiber optic cabling is the primary choice for Ethernet 100BASEFX networks, copper cabling can also be used for short-range connections. This is known as 100BASE-TX and utilizes Category 5 (Cat5) or higher grade twisted-pair cables. Copper cabling is cost-effective and widely available, making it a suitable option for smaller networks or scenarios where fiber optic cabling might not be feasible.
标题级别3：Limitations of Copper Cabling
Despite its affordability and availability, copper cabling has a number of limitations compared to fiber optic cabling. It is susceptible to electromagnetic interference, has shorter maximum transmission distances, and lower bandwidth capabilities. These factors restrict its usage primarily to short-range connections within a limited geographic area.
标题级别2：结论
综上所述, Ethernet 100BASEFX networks predominantly use fiber optic cabling for data transmission. Single-mode fiber is suitable for long-distance applications, while multi-mode fiber is ideal for shorter-range connections. Copper cabling can also be implemented for short-range connections, although it has certain limitations regarding distance and bandwidth. Understanding the different cabling options available for Ethernet 100BASEFX networks is crucial in designing and implementing efficient and reliable network infrastructures.
