Understanding the Diversity of Computer Network Cables


Network Drops is your go-to for computer network cables and your business’s computer network cabling needs

Choosing the right type of computer network cable for your New Jersey or Pennsylvania business is pivotal in establishing a reliable network infrastructure that underpins various business functions. The array of available cables serves diverse industry needs, with each type offering distinct advantages and considerations.

What are the four main types of computer network cable?

UTP cable is commonly used in ethernet networks for data transmission. It is made of multiple unshielded twisted pairs of copper cable. A shielded twisted pair (STP) cable has a metal shield for better protection against signal loss and interference.

Optical fibers, known for their high transmission speed over long distances, surpass the capabilities of traditional copper cables. Different colored cables with varying speeds are important for networks. UTP cables are affordable, while STP cables are better for places with interference. Understanding the nuances among different types of network cables is essential for ensuring optimal performance and reliability within complex networking setups.

Coaxial cables

Coaxial cables have a copper conductor in the middle, insulation, and a metal shield. They are known for resisting interference. This design makes them a popular choice for telecommunication applications where data integrity is paramount. Coaxial cables are strong and can transmit data over long distances. Therefore, they are commonly used for internet and cable TV networks.

Fiber Optic Cables

Fiber optic cables, comprising a glass core and multiple protective layers, transmit light instead of electronic signals. This property ensures minimal susceptibility to electrical interference, which is a common issue with other cable types. Fiber optic cables are great for fast internet, phone calls, and cable TV. They use glass to send light signals quickly and accurately over long distances.

Their ability to maintain signal strength over vast distances, coupled with their immunity to interference, contributes to their growing popularity in modern networking environments. Ethernet cables are a good choice for connecting networks between buildings. They can handle moisture and electrical problems, which shows their reliability in tough conditions.

Shielded Twisted Pair (STP) Cables

Shielded Twisted Pair (STP) cables, also known as Ethernet cables, utilize copper wiring with an added external shield for grounding. These cables are great for reducing interference, extending connections, and creating a reliable network environment. The shielding layer effectively reduces electrical noise, making STP cables perfect for use in environments with potential electromagnetic interference (EMI).

This includes setups with many electronic devices or large machinery that may disrupt the data transmission. As such, STP cables are a trusted solution for businesses requiring reliable data flow in complex, interference-rich networking environments.

Unshielded Twisted Pair (UTP) cables

Unshielded Twisted Pair (UTP) cables, another variant of Ethernet cables, are composed of twisted pairs of conductors. The twist rate (how many twists per meter) varies among different categories of UTP cables and impacts their ability to transmit data over distance.

The twisting helps to counteract electromagnetic interference from external sources, thereby improving the integrity of the data transmission. UTP cables do not include shielding, making them lighter, more flexible, and less expensive than STP cables.

However, this lack of shielding makes UTP cables more susceptible to electromagnetic interference than their shielded counterparts. Despite this, their affordability and easy installation make them popular for Ethernet and phone connections, especially in offices.

Recap of the four types of network cables

Understanding the strengths and applications of each type of computer network cable empowers businesses to make informed decisions when establishing a robust network infrastructure. Let’s delve deeper into the specifics of each type:

  • Coaxial Cables are ideal for enterprises that need dependable data transfer over considerable distances, like telecommunication and cable TV networks, where the preservation of data is critically important.
  • Fiber Optic Cables excel in high-speed internet, telecommunications, and cable TV applications. Their minimal susceptibility to electrical interference and signal loss, and ability to maintain signal strength over vast distances make them ideal for connecting networks across different buildings.
  • Shielded Twisted Pair Cables (STP)are ideal for environments prone to electromagnetic interference. STP cables are used in industries with lots of electronics or big machines to keep data flowing smoothly in busy networks.
  • Unshielded Twisted Pair Cables (UTP) are a versatile choice for ethernet and telephone connections. The design of these cables makes them resistant to electromagnetic interference from external sources, making them a reliable choice for various industry applications.
