Three Major Types Of Network Cables Used In Communication Systems

Fiber optic cable, twisted pair cable, and coaxial cable are the three main types of network cables used in communication systems. Each of them is different and suitable for various applications.

Fiber Optic Cable

Fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.

Fiber Optic cable has a complicated design and structure. This type of cable has an outer optical casing that surrounds the light and traps it within a central core. The inside of the cable (the core) must configured in two different ways – Single-mode and multi-mode; although the difference may seem small, it makes a tremendous difference to the performance and the usage of fiber optic cables.

Twisted Pair Cable

Twisted pair cable is a type of ordinary wiring which connects home and many business computers to the telephone company. It is made by putting two separate insulated wires together in a twisted pattern and running them parallel to each other, which helps to reduce crosstalk or electromagnetic induction between pairs of wires. Twisted pair cable is suitable for transferring balanced differential signals. The method of transmitting signals dates back to the early days of the telegraph and radio. The advantages of improved signal-to-noise ratio, crosstalk, and ground bounce that balanced signal transmission brings are particularly valuable in wide bandwidth and high fidelity systems.

According to whether the cable has a shielding layer, there are two common types of twisted pair cables—shielded twisted pair (STP) cable and unshielded twisted pair (UTP) cable. STP cable is available for Token Ring networks, while the UTP cable is more suitable for Ethernet networks. The most common UTP cable types applied in Ethernet network are cat5e, cat6a, and cat7 cables, etc. The following image shows the different structures of UTP and STP cables.
