Network Cable Types

Network Cabling is the Layer 1 of OSI Model. One of the most important part of a network. With the media the network traffic can travel from one end to the other end. This can be done through wireless networks also. But network cabling is always used even if wireless networks are used.

 

Different networks and interfaces require various cable types. Twisted-pair cables, Optical cables, Coaxial cables are the common cable types.In this article, we will focus on these cable types and we will talk about them detailly.

 


Ethernet Cables

To talk about cable types in network cabling, let’s start with Ethernet Standard. As you know Ethernet, is one of the Layer 2 standard that is commonly used. There are different cable types that are used with Ethernet Standard. These are:

 

  • Ethernet 10Base-T (10 Mb/s)
  • Fast Ethernet 100Base-T (100 Mb/s)
  • Gigabit Ethernet 1000Base-T (1000 Mb/s)
  • 10 Gigabit Ethernet 10000Base-T (10000 Mb/s)

 

Ethernet (10Base-T) is provided with Copper Twisted Pair cables. There are two standard for Ethernet (10Base-T):

  • 802.3i (10Mb/s – half-duplex)
  • 802.3x (10Mb/s – full-duplex)

 

 

Fast Ethernet (100Base-T) is know as 802.3u in network cabling and it has also Half and Full duplex modes. Normally it is used withing 100meters but according to the cable type used, this can be changed. If Multi Mode SFP (Fiber Optic) is used, then this distance can be up to 2km. If Single Mode is used, then the distance can be up to 25 km.

 

The types of Fast Ethernet are :

  • 100Base-TX (Provide by 2 pairs of Twisted Pair), 100m
  • 100Base-T4 (Provide by 4 pairs of Twisted Pair), 100m
  • 100Base-FX (Provide by Optical Cable), 2km, Multi Mode SFP
  • 100Base-FX-SM (Provide by Optical Cable), 25km, Single Mode SFP

 

Below, you can also watch Network Cabling Video Lesson:

Gigabit Ethernet (1000Base-T) is know as 802.3ab and it has only Full-duplex mode. It provides 100 meters with 4 Pair Category 5 (CAT5). But if we use Fiber Optic Multi Mode SFP, then this can be up to 550 meters. And if we use Single Mode this can be up to 70 km. Here, the SFP type is important. Different SFP types even if they are Single Mode, support different distances.

 

  • 1000Base-TX (up to 100m)
  • 1000Base-LX (up to 10km)
  • 1000Base-SX (up to 550m)
  • 1000Base-ZX(up to 70km)

 

10 Gigabit Ethernet (1000Base-T) is know as 802.3ae in network cabling and it is used only with Optical cables. With Multi Mode, it is up to 300 meters. But with Single Mode SFPs, this distane can be up to 80 km.

 

Fiber Optic cables are high capacity cables. Beside lower speeds, they are also the cables that is used for 100Gbps connections.

Fiber Optic Cable Types

In network cabling Fiber Optic cables has two different modes. These two modes are given below:

  • Multimode Fiber
  • Single Mode Fiber

 

There are also different types of each Fiber Optic Cable Mode.

Multimode Fiber Optic Cable Types are:

  • OM1
  • OM2
  • OM3
  • OM4
  • OM5

Single Mode Fiber Optic Cable Types are:

  • OS1
  • OS2

  • CAT6a (Max 10 Gbps over 100 m) 500 MHz,
  • CAT7 (Max 10 Gbps over 100 m) 600 MHz
  • CAT7a (Max 10 Gbps over 100 m) 1000 MHz

Serial Cables

Serial cables are the legacy transport mechanisms. It is evolving through the USB. But it is good to know about them even if they are old technology. There are two types important Serial cables. These are:

  • RS-232
  • RS-422

Frequently Asked Questions About Network Cabling

What Are the Main Types of Network Cables?

There are three main types of network cables. These are twisted-pair copper cables, fiber-optic cables and coaxial cables. Twisted-pair cables are commonly used in Ethernet LANs, fiber-optic cables support high-speed and long-distance communication and coaxial cables are primarily used in cable Internet and legacy networking systems.

 


What Is the Difference Between Cat5e and Cat6 Cables?

Cat5e and Cat6 are both Ethernet cable categories that use RJ45 connectors. Cat6 supports higher bandwidth and better performance over shorter distances, making it more suitable for Gigabit and 10 Gigabit Ethernet deployments.

 


Can I Use a Cat6 Cable Instead of Cat5e?

Yes. Cat6 cables are backward compatible with Cat5e and can be used with the same RJ45 connectors. But here, your network speed will still depend on the capabilities of the connected equipment.

 


Which Network Cable Is Best for Home Use?

For most home networks, Cat6 Ethernet cable is the best choice because it offers excellent performance, supports Gigabit networking and provides better protection against interference than Cat5e.

 


Which Cable Is Used for Long-Distance Networking?

Fiber-optic cable is the preferred for long-distance networking because it supports much greater distances, higher bandwidth and is immune to electromagnetic interference than twisted-pair cables.

 


What Is the Difference Between Copper and Fiber Optic Cables?

The main differences between copper and fiber optic cables are their transmission method and their typical networking applications. Copper cables transmit electrical signals and are commonly used in local Ethernet networks. On the other hand, fiber optic cables transmit light signals and can be used both in local networks and in long distances. Here, fiber optic provides higher bandwidth, longer transmission distances and immunity to electromagnetic interference.

 


Can Fiber Optic Cables Be Bent?

Yes, but only within their specified minimum bend radius. Excessive bending can increase signal loss or permanently damage the optical fiber.

 


Which Network Cable Is Most Commonly Used for Ethernet?

Twisted-pair Ethernet cables such as Cat5e, Cat6 and Cat6A are the most commonly used network cables for Ethernet LANs in home networks, office and enterprise networks.

 


What Is the Difference Between Shielded and Unshielded Ethernet Cables?

STP (Shielded Ethernet cables) include additional shielding to reduce electromagnetic interference, making them suitable for electrically noisy environments. UTP (Unshielded twisted-pair ) cables are more common, easier to install and sufficient for most office and home networks.

 


Can Different Types of Network Cables Be Used Together?

Yes. Different cable types can coexist within the same network. But generally we use them for different roles. For example, fiber-optic cables are commonly used for backbone connections, while Cat6 Ethernet cables connect end devices to switches.
