For a 100BaseT Ethernet network, the appropriate type of cabling is Category 5 UTP (Unshielded Twisted Pair). This standard supports data rates of up to 100 Megabits per second (Mbps) and is specifically designed to handle the requirements of 100BaseT networking. Category 5 UTP cables consist of four twisted pairs of wires, which help reduce interference and maintain signal quality over distances up to 100 meters.

While Category 6 UTP is also capable of supporting 100BaseT connections and offers improved performance and reduced crosstalk at higher frequencies, it is not necessary to utilize that level of cabling for 100BaseT applications. Coaxial cable was primarily used in older Ethernet standards such as 10Base2 and 10Base5, and is not suitable for modern 100BaseT networks. Fiber optic cables can support much higher speeds and longer distances but are not strictly required for a 100BaseT setup, making Category 5 UTP the most appropriate and cost-effective choice for this type of network environment.
