What Is a Network Cable and How Does It Work?

A network cable is a physical cable that carries data between network devices. It can connect computers, routers, switches, access points, IP cameras, servers, and other equipment.

Most modern wired networks use Ethernet over twisted-pair copper cables or fiber optic cables. The process can be explained simply as follows:

1. A machine generates digital data.

2. The networking hardware converts the data into signals.

3. The signal gets transmitted across the network cable.

4. The receiving machine converts the signal back to data.

Copper Ethernet cables use electrical signals. The fiber optic cable uses light signals. While coaxial cables make use of electrical signals, they have a different construction than that of copper Ethernet cables.

There are various Ethernet standards available for varying transmission rates and physical media. In addition to that, the IEEE 802.3 standard also includes Power over Ethernet cabling.

For Example

Think of a network cable as a road.

The data is the traffic.

The cable is the road.

A better road design can carry more traffic with fewer problems. But building the widest road does not always make sense. You need the right road for the amount of traffic, distance, and location. The same idea applies to network cables.

Types of Network Cables

For modern homes and offices, twisted pair Ethernet is usually the cable type people encounter most. Fiber becomes more important when the network needs longer distances or higher capacity.

The main network cable types include:

Coaxial Cable

Coaxial cable has a central conductor surrounded by insulation, shielding, and an outer jacket. Its design helps protect the signal from external interference.

Coaxial cable was used extensively in early Ethernet networks. Today, it is less common for standard computer LAN connections, but it still has important applications in broadband, cable television, CCTV, and other communication systems.

Common uses include:

• Cable TV connections

• Broadband connections

• CCTV and surveillance systems

• RF communication

• Specialized communication equipment

For a new office Ethernet network, twisted pair or fiber is usually more relevant. But for a broadband or video system designed around coaxial infrastructure, replacing it with another cable type may not be necessary.

Fiber Optic Cable

Fiber optic cable sends information through pulses of light. 

Fiber has important advantages for long-distance and high-bandwidth applications. Single-mode fiber is commonly used for metro, access, and long-haul applications. Multimode fiber is more common for shorter links inside buildings and campuses. 

Fiber is also not affected by electromagnetic interference in the same way as copper. This makes it useful in environments where electrical noise can create problems for copper connections.

Fiber is commonly used for:

• Network backbones

• Data centers

• Campus networks

• Telecommunications

• Long-distance connections

• High-speed links between network buildings

For example, OM3 and OM4 multimode fiber can support 10 GbE over hundreds of meters, while single-mode fiber is designed for much longer links.

Twisted Pair Cables

When people talk about Ethernet cables, they often mean twisted pair cables. The copper conductors are arranged in pairs and twisted together. This design helps control interference and crosstalk between the conductors.

Common categories include:

The numbers in this table describe cabling characteristics, not guaranteed internet speed. Your router, switch, network interface, connectors, installation quality, and service all affect actual performance.

Shielded Twisted Pair (STP) Cable

Shielded twisted pair cable contains twisted copper pairs with an additional shield. The shield helps reduce the effect of electromagnetic interference and radio frequency interference.

STP can be useful in places such as:

• Factories

• Workshops

• Data centers

• Areas close to heavy electrical equipment

• Locations with significant electromagnetic interference

However, shielding is not automatically better for every installation. A shielded system needs suitable components and proper installation. The grounding and bonding arrangement also matters.

Unshielded Twisted Pair (UTP) Cable

UTP cable does not have an additional metallic shield around the twisted pairs. It is widely used for Ethernet networks in homes, schools, offices, and commercial buildings.

UTP is popular because it is:

• Easy to install

• Flexible

• Widely supported

• Available in many categories

• Suitable for many standard Ethernet applications

The cable category matters more than simply choosing between UTP and STP.

Network Cable Bandwidth vs Speed: What Is the Difference?

A cable's bandwidth rating is usually expressed in megahertz (MHz), while network speed is expressed in megabits or gigabits per second (Mbps or Gbps).

In simple terms:

• MHz describes the frequency range used to characterize the cabling.

• Mbps/Gbps describes the data rate.

• Cable type describes how the cable carries the signal.

• Cable category describes the performance requirements of a particular copper twisted pair cable.

Suppose you see:

Cat6: 250 MHz

and

Cat6A: 500 MHz

It does not mean that Cat6A provides twice the internet speed. The MHz figure describes the cable's frequency performance. The actual network data rate depends on the Ethernet technology running over the cable.

The table below compares the main cable types used in networking.

Identifying Specific Uses for Different Network Cable Types

The best network cable depends on where you will use it, how far the connection must travel, and how much speed your network needs.

Use the table below as a quick guide.

Factors to Consider While Choosing a Network Cable

Buying the highest category cable is not always the right approach. Instead, look at the complete network.

Ethernet Cable Requirements

A high-category cable cannot make a device support a speed that its network hardware does not support. Check the specifications of:

• Routers

• Switches

• Network interface cards

• Wireless access points

• IP cameras

• Servers

• PoE devices

Compatibility

Your cable must work with the network equipment and connectors. Check the cable category, connector type, Ethernet standard, PoE requirements, and installation components before buying.

Cost

Price should be considered with the complete installation cost. A cheaper cable may cost more in the long run if it needs to be replaced during a network upgrade.

At the same time, buying a very high specification cable for a basic application may provide little practical benefit.

Network Speed

A basic Gigabit network has different requirements from a 10 GbE office backbone or a 25G data center connection. The IEEE 802.3 family covers Ethernet from low-speed applications through very high-speed systems, using different physical media and technologies.

Bandwidth

Cable frequency rating affects the transmission characteristics of the cabling. Do not confuse these numbers with your internet package speed.

Industry Standards

Look for cables and components that meet the relevant cabling standards. Standards help define the electrical, mechanical, and transmission characteristics that a network needs.

Scalability and Futureproofing

Think about what your network may need in the next few years. You may be installing a cable today but keeping it inside a wall or ceiling for a long time.

EMI

EMI means electromagnetic interference.

It can come from electrical equipment and other sources of electromagnetic energy. If your cable passes close to equipment that creates significant interference, cable construction becomes more important.

Shielded cabling can help in suitable installations. Fiber provides another option where electrical isolation is important.

Distance

Distance affects cable choice. For copper Ethernet, 100 m is an important reference point for many structured cabling applications. Fiber can support much longer distances.

Environment

A network cable installed inside an office has different requirements from one installed in a factory. The cable must be suitable for its actual installation environment.

Check the cable jacket and environmental rating when the cable will face:

• High temperatures

• Low temperatures

• Moisture

• Chemicals

• Outdoor exposure

• Industrial conditions

Physical protection matters too.

Think about:

• Bending

• Crushing

• Pulling

• Foot traffic

• Sharp edges

• Rodents

• Outdoor exposure

• Cable tray conditions

How to Choose the Right Network Cable?

Use this simple process before buying.

Step 1: Check your network speed

Step 2: Measure the distance

Step 3: Choose copper or fiber

Step 4: Select the cable category

       For:

• Basic home network: Cat5e or Cat6

• New home wiring: Cat6

• 10 Gb Ethernet: Cat6A or fiber

• Standard office network: Cat6

• Future-focused office installation: Cat6A

• Short high-speed data center connection: Cat8

• Long-distance connection: Fiber optic

• High EMI environment: Shielded copper or fiber

• IP cameras: PoE compatible Cat5e, Cat6, or Cat6A

• Wi Fi access points: PoE-compatible Ethernet cable

Step 5: Check the environment

Step 6: Check PoE requirements

Step 7: Plan for future upgrades

The final choice should always match the network equipment, required speed, cable distance, installation environment, and future upgrade plans.

Conclusion

Selection of the network cable becomes easier if one stops considering the category of the cable alone. Consider your needs first. Determine the network speed, distance, bandwidth, equipment compatibility, PoE requirements, environment, interference, and the plan for expansion in the future.

If you require a short connection for the high speed application of data centers, you should go for the Cat8. It can provide speeds of 25G and 40G up to 30 m.

In case of longer distance requirements, use fiber optic cable. Before purchasing, compare the cable with your equipment and the requirements of the installation.
