The document compares different wired transmission media, including unshielded twisted pair (UTP), shielded twisted pair (STP), coaxial cable, and fiber optic cable. It discusses their structures, performance in terms of bandwidth, attenuation, segment length, installation cost, susceptibility to interference and crosstalk, and typical cost per meter. UTP has the lowest cost but also the lowest bandwidth and highest attenuation. Fiber optic cable has the highest bandwidth and lowest attenuation but also the highest installation cost.
