When you talk about Cat 6 cables, you are aware of the fact that they are ethernet cables that are based on a single specification and low voltage twisted pair cables. However, for those who may not be aware, these cables can be classified into two types which include STP (Shielded Twisted Pair ) or UTP (Unshielded Twisted Pair).
At times, choosing between UTP and STP cables when purchasing Ethernet cables for data transmission can become confusing. So how do you choose between the two? What is the difference between UTP and STP cables? and others remain a constant question. So let’s take a closer look to make an informed choice.
All About UTP Cables
UTP Cables or Unshielded Twisted pairs are widely used as telephone cables. The two insulated conductors, most precisely copper are twisted together to make up a twisted pair. As they are unshielded, they do not come with an outer layer of insulation.
With this frequency range, both voice calls and data transfer becomes easier. Also, they are the best choice when wanting to connect computers to the network. In addition to this, the Cat6A UnShielded (UTP) Ethernet network cables are said to be less expensive compared to the STP cables.
What are the Features of UTP Cables?
The Cat6A UnShielded (UTP) Ethernet network cables come with several features that differentiate them from the STP cables. To know about the features, keep reading below.
When compared to the other kinds of network cables, these are a very budget-friendly option.
These cables are a popular option for industries that require small and medium-sized networks.
The UTP cables are easier to install anytime.
They can transfer data only at a certain distance which is approximately around 100 meters in range.
These are susceptible to interference from all types of electromagnetic radiation.
All About STP Cables
When talking about shielded twisted pair cables or STP, they come with metal aluminium foil. There is a coiled mesh present which covers each pair of insulated conductors. As it is in the metal cage, it reflects electromagnetic radiation.
This also somehow helps to improve the stability of appropriate data interchange and communication. The Cat6A Shielded (STP) Ethernet network cable are typically used to connect computers to the network which makes them perfect for the industrial environment or areas having increased electromagnetic sound.
What are the Features of STP Cables?
Before knowing the difference between UTP and STP cables, let’s find out what the features of the Shielded Twisted Pair cables are.
The STP cables are protected against electromagnetic interference as they have a layer of metal foil available.
They are not at all easy to install as they require specialized knowledge. As a result, installation costs may increase as well.
These are perfect for industries that require high-bandwidth applications.
The STP cables are expensive as they need more shielding which increases the manufacturing expense.
When compared to UTP cables, they can transfer data quickly.
Are There Any Drawbacks to The UTP and STP Cables?
There are several drawbacks that the UTP and STP Cables bring along. To know what problems you may encounter by choosing them, read the cons below.
Cons of Choosing UTP Cables
They are prone to electromagnetic interference.
These are known to be less robust which makes them prone to damage.
Cons of Choosing STP Cables
These are less flexible
It can get daunting to install them without any prior knowledge.
These are highly prone to crosstalk when compared to the Cat6A Unshielded (UTP) Ethernet Network Cable.
UTP Vs STP – Know the Distinction Between The Two
Now that you have known the specifications, features and cons, let’s find out the difference between UTP and STP cables to get a closer perspective.
| Differences | UTP Cables | STP Cables |
| Structure | These cables are twisted together. | These are twisted pair cables which are covered in a foil or shield. |
| Installation | They can be easily installed. | These can be difficult to install |
| Cost | These are affordable. | They are expensive. |
| Maintenance | The UTP cables do not require much maintenance. | These require maintenance more than UTP cables. |
| Shielding from EMI | They do not provide great shielding from EMI. | The STP offer great protection from EMI. |
| Speed | The UTP support slower speed. | These offer higher speed when compared to the UTP cables. |
| Flexibility | More flexible. | Less flexible. |
| Grounding Requirement | No need for grounding. | Grounding is essential. |
| Number of Nodes | There are a maximum of 1024 nodes present. | The maximum number of nodes present in STP cables is around 270. |
| Crosstalk | Less prone to crosstalk. | More prone to crosstalk. |
| Data Transfer | The data transfer in UTP is slower than in STP. | Offers high and stable data transferring. |
| Noise Interference | There is higher noise interference. | The noise is less in STP. |
| Weight | They are lightweight. | These are heavier than UTP. |
| Target Usage | Telephone wiring, local network areas and more. | Areas with frigid temperatures or high radiation conditions. |
What are FTP Network Cables? How Are They Different from UTP Cables?
Besides UTP and STP cables, there are FTP cables as well which one must know of. The FTP cables stand for Foiled Twisted Pair in which a foil shields the cable. This shield works as a protection against electromagnetic interference both internally and externally for the cable. When digging deeper to know the answer to UTP vs. FTP Network Cable – check below.
UTP comes with high cross-talk, while FTP comes with low cross-talk.
There are no cable shields present in UTP. But FTP comes with a foil shield as mentioned above.
Both bonding and grounding are required in FTP, whereas UTP does not demand any.
FTP has a higher data rate compared to UTP.
UTP is cheaper, but FTP is moderately expensive.
FTP is great for long-distance networks. Whereas, UTP can be used in home networks
Is STP Ideal Than UTP?
STPs perform better when talking about performance as they can transmit greater data compared to UTP. Simply because they contain an extra mesh shield which prevents crosstalk and shields the connection from EMI.
Apart from this, STP extra shielding raises installation costs and challenges which is more than Cat6A UnShielded (UTP) Ethernet Network Cable. Additionally, UTP is more affordable and simpler to install and maintain which makes it a preferable option for networks in homes and businesses.
UTP or STP – Which Should Be Used?
After knowing the difference between UTP and STP cables, you may find it confusing to make a better choice. Well, in that case, you must know that when searching for something less expensive, UTP is the best choice. Also, they should be chosen if you are seeking a simpler installation process. They are regarded as the best choice for networks in homes and small office areas.
While Cat6A shielded (STP) Ethernet network cable is an ideal choice when aiming for protection from electromagnetic interference,. They are regarded as superior for business networks. Additionally, they are the best pick if you need robust cables. Moreover, when talking about enterprise networks, both of them can be used.
