What type of network is based on the 100BASE-TX Fast Ethernet standard?

The 100BASE-TX Fast Ethernet standard specifically refers to a type of wired network that primarily uses twisted-pair cabling, which is a form of copper cabling. This standard supports data transmission speeds of up to 100 Mbps over distances of up to 100 meters. The 100BASE-TX standard utilizes two pairs of wires within a Category 5 (or higher) twisted-pair cable, making it a copper-based technology.

While the 100BASE-TX standard does not directly specify the use of fiber optic connections, it is common in networking to deploy mixed environments where both fiber optics and copper cabling are used. For instance, fiber may be used for backbone connections to cover longer distances or connect different network segments efficiently. Therefore, considering that the question might refer to typical networking scenarios where 100BASE-TX connections are part of a broader network topology, a mix of fiber and copper can be applicable.

This is not to say that 100BASE-TX is fiber optic only, which eliminates that choice, nor does it deal with coaxial cables or wireless connections, both of which are separate technologies not associated with the 100BASE-TX standard.
