Coaxial Cable
This type of cable is commonly used in older buildings. It uses a copper core surrounded by an insulating material, then a metal sheath. The metal sheath gives it strength while keeping out outside elements such as water or dirt. It is straightforward to install and is often used in home networks. This type of cable is not recommended for use in commercial buildings because it can only transmit signals over short distances.

Fiber Optic Cable
This type of cable was developed as a replacement for coaxial because it can carry more data over longer distances with less loss than coaxial cables. Fiber optic cables consist of two thin pieces (sometimes called fibers) made from plastic or glass that transmit information through pulses of light instead of electricity, like other types of cables do. They have several advantages, including faster transfer rates, greater bandwidth capacity, immunity from electromagnetic interference, longer distances between nodes (100 meters compared to 10 meters on UTP), resistance against corrosion and fire damage if sealed adequately at each endpoint within a conduit leading outside building walls which may contain one or more fiber optic pair(s).

Shielded Twisted Pair (STP) Cable
Shielded twisted pair (STP) cable is a single-pair wire consisting of four pairs: two pairs for transmitting signals and two for receiving them. This type of cable is commonly used in telephone systems and computer networks because it can withstand interference from power lines, radio waves, and other sources that could otherwise disrupt regular operation by introducing noise into signals being transmitted over long distances via copper wire connections between servers or desktop computers located within buildings.

Unshielded Twisted Pair (UTP) Cable
Unshielded twisted pair (UTP) is most commonly used in telephone lines because it is cheaper and easier to install than other cabling systems, such as fiber optic cable or coaxial cable. UTP is also used in computer networks because it can be run through walls and ceilings without needing additional tools or special equipment. This cabling system relies on copper wires that are twisted around each other to reduce interference from external sources that could disrupt data transmission over long distances via copper wire connections between servers.
