What Is The Difference Between UTP And STP Cables

One of the biggest concerns that come across while installing network wiring is to select one of the two twisted pairs of the cable. Two conductors of a single circuit are twisted together with a purpose to improve electromagnetic compatibility. It is better to consider twisted pair cable than single conductor or an untwisted pair of cables, because a twisted pair has potential to reduce crosstalk between neighboring pairs, electromagnetic radiation and enhances rejection or interference.

Twisted pair cables are segregated into two categories, shielded and unshielded. Both the types have different pros, cons and applications. Along with these two types of twisted pairs, there are other two types of cables. It comprises of coaxial and fiber optic cable.

Twisted pair cables are generally used for Ethernet connections and telephone. The reason behind it is that it has pairs of wire that are twisted to avoid crosstalk hindrance. It is one of the most common culprits that cause inefficiency in the networking systems. Therefore, twisted pair cables can be efficiently used for network communications.


UTP is an acronym of Unshielded Twisted Pair Cable. Despite having the name of no coating, it has a protective layer of an insulating material that coats each wire from the total of eight copper wires that present in cable. The only difference is that it has a coating layer but has no shielding. Sometimes, it is required for efficient transmission.

On the bright side, unshielded twisted pair cable has made a long journey in recent times to be proved that it still offers faster transmission than STP. Above all, the usage of UTP in the Cat6 plenum cable proves to be an efficient medium for networking. It also works well with category 5 cables for making right operations.


STP is nothing but the extended concept of UTP. It is an acronym of Shielded Twisted Pair. It offers advancement to the networking system as compared to UTP.

STP cables have pairs of wires that are shielded by a metallic substance. All these pairs are coated with another protective metallic layer. The intention behind this heavy layering is to prevent interference in the transmission. However, this protection is not just offered through shielding. It makes a great combination with cancellation and wire twisting. All these three techniques prove to be an efficient one to protect from any inefficiency.

Though STP cable is having a plethora of advantages, it also has a drawback. Its darker side demonstrates that it is quite difficult to install. Installing STP cable is no joke. It becomes imperative to take efficient care while doing so. In case it is not grounded from both the ends, you’re liable to deal with many issues along with crosstalk.

Over To You

When it comes to compare UTP and STP, there is no clear-cut victory between the two. Each one has its pros and cons. To select an efficient one between these two, you have to contemplate your budget and the situation. While getting one for your house see to it that you buy from a reliable provider such as Vertexcables.com. For your better selection, we’ve summarized and brought you a clear comparison between the two.

    • STP cables are more expensive than UTP cables.
    • UTP cables are unshielded, whereas STP cables are shielded.
    • STP cables are heavier than UTP cables.
    • STP cables offer better resistance to interference and noise as compared to UTP.
    • UTP cables are considered to better in SOHO networks, whereas STP cables are preferred for high-end applications.
  • While striving to get better maximizing bandwidth, STP cables are better than UTP.
