UTP vs STP: Difference and Comparison

The twist in the cable cancels out any electromagnetic disturbance that may emerge in the cabling. Twisted pair connectivity is categorized into two categories: STP and UTP.

All these UTP and STP are frequently utilized for long-distance data transmission. UTP is a connection with braided wires that reduces noise created by an independent factor.

Key Takeaways

  1. UTP cables have unshielded twisted pairs, making them more affordable and easier to install, while STP cables have shielded twisted pairs, offering better protection from electromagnetic interference.
  2. STP cables provide a higher level of noise immunity, enhancing signal transmission quality in environments with significant interference.
  3. UTP cables are more common in residential and small office settings, while STP cables are ideal for industrial or high-interference environments.


UTP and STP differ because UTP stands for ‘Unshielded twisted pair’ whereas STP is the acronym for ‘Shielded twisted pair’. Even though the engineering and manufacturing style of both are distinct, each fulfils the same goal. The primary distinction between UTP and STP would be that UTP (Un-shielded twisted pair) is a connection with twisted conductors that reduces noise and interference. STP (Shielded twisted pair) is a type of cable encased in a foil or mesh shielding that protects the line from electronic radiation.


UTP transmission medium is a form of coaxial cable. It is an abbreviation for Unshielded twisted pair.

STP, which represents a ‘Shielded twisted pair’, is another sort of twisted ensemble. A neutralizing cable is needed for STP.

A metallic shield shields cables from radio and electrical noise in STP. This improves reliability and accelerates data transfer in facilities using microwave equipment, HVAC, or two-way radios.

What is UTP?

Its frequency band is suited for both internet and phone transmission. As a result, they are by far the most widely utilized in communications services.

Color stripes are used to identify plastic encapsulation. Colors can also be used to identify particular conductors in a wire and to show which conductors belong in pairings and how these relate to other pairings in a bigger bundle.

Noise is produced when cables are interconnected, resulting in a rise in operating voltage in the cable nearest to the source, an unequal load, and a corrupted transmission.

Because of its reduced cost, UTP cable is the most common and widely utilized cabling in most homes, workplaces, and even big organizations. As a consequence, it is broadly applied in telephones, desktops, and other electronic devices.

What is STP?

Every set of conductive materials is shielded (STP) wire wrapped in a woven mesh covering or metal alloy. The metal shell prevents electrical noise from penetrating.

It is also referred to as a cable with a metallic sheath or coating that surrounds each pair of conductive materials to protect them from multiple stakeholders and to prevent radio noise from entering.

The insulation also adds weight to the wire, making it more difficult to bend or alter in any manner. This is not a major issue, and it is something that users ought to be aware of when deciding between STP and UTP.

Main Differences Between UTP and STP

  1. the general bandwidth.
  2. UTP cables are quick to set up, however, STP cables are harder to configure since they are larger, heavier, and firmer.
