Which type of cable does NOT contain additional shielding like meshes or aluminum foil?

Unshielded Twisted Pair (UTP) cable is characterized by its lack of additional shielding such as meshes or aluminum foil, which distinguishes it from other types of cables that do include these protective measures.

In networking applications, UTP is commonly used due to its simple construction and cost-effectiveness. Each pair of wires is twisted together to reduce electromagnetic interference (EMI), but it does not have an overall shield. This makes UTP suitable for many applications, particularly in environments with lower levels of interference.

The absence of shielding in UTP allows for a thinner, more flexible cable design, making it easier to install in various scenarios. This absence of shielding, while making the cable more susceptible to interference compared to shielded cables, is often more than adequate for many standard telecommunications and data networking environments.

Other cables mentioned, such as Shielded Twisted Pair and Coaxial Cable, incorporate shielding to provide greater immunity against outside interference. Braided Shielded Cable also offers substantial shielding, making all these alternatives more robust in situations where EMI is a concern.
