1. Introduction


Ethernet cables widely used today include Cat 5e, Cat 6, Cat 6a, Cat 7, and Cat 8. Within these cable categories, they are further differentiated based on their shielding levels, which include UTP, STP, FTP, and S/FTP. Shielding involves the application of protective materials around the cable to minimize electromagnetic interference, radio frequency interference, and crosstalk between wires. The most commonly used shielding types are UTP, STP, and FTP.


The question that arises is how to choose among these three shielding levels – UTP, STP, and FTP. This article aims to explore and address this question in-depth. Join us as we delve into the considerations for selecting the appropriate shielding level based on your specific networking requirements.




2. What is UTP?


UTP, also known as Unshielded Twisted Pair, is a commonly used cable for Ethernet connections. It involves twisting multiple pairs of wires together, providing a degree of immunity to interference and crosstalk. However, this type of cable lacks any additional shielding throughout its structure; it only has insulation and a protective sheath. Despite the absence of shielding, UTP remains a popular choice for many due to its cost-effectiveness and ease of installation. Users appreciate that it doesn't require extra shielding materials, and there's no concern about damaging a braided shielding layer, making it a convenient option.


In terms of Power over Ethernet (PoE) support, not all UTP cables are compatible. The capability depends on the specific type or category of UTP cable. To support PoE, cables need to meet certain electrical characteristics and specifications. Generally, Cat5e, Cat6, Cat6a, Cat7, and higher-category UTP cables are preferred for PoE applications.

3. What is FTP?


FTP, also known as Foil Twisted Pair, is composed of multiple pairs of insulated copper wires twisted together, with each wire pair individually wrapped in its foil shielding. This design aims to protect the cable from electromagnetic interference and crosstalk.


FTP commonly uses two ports: a control connection port (Port 21) and a data connection port (Port 20). While these default ports are widely used, FTP can be configured to use different ports. Additionally, when using FTP over a secure connection, different ports are often employed. The specific port configuration depends on the settings of the FTP server and its implementation.


You might wonder if FTP can operate over WiFi. The answer is affirmative – FTP can function over WiFi just as it does over wired connections. Whether through WiFi or wired connections, protocols like FTP operate transparently at the application layer. Devices connected to the same WiFi network can use FTP for file transfers, provided the FTP server is configured to accept connections over the WiFi network.



4. What is STP?


STP, or Shielded Twisted Pair, is a type of twisted pair cable used for transmitting data in networks. In STP, multiple pairs of wires are twisted together, with each pair individually wrapped in a metallic foil shielding. Additionally, all four pairs are encased in a common metal braided shielding layer. This design aims to protect the cable from electromagnetic interference and radio frequency interference.


STP requires the use of a grounding cable. It demands more maintenance compared to UTP, making it a higher-cost option due to the multiple layers of shielding for protection. Installation can be more complex due to the additional shielding layers, but in return, STP provides higher resistance to interference compared to FTP.
