LAN Network Cable Media and Connectors

This tutorial explains the types of network cables used in computer networks in detail. Learn the specifications, standards, and features of the coaxial cable, twisted-pair cable, and the fiber-optical cable. To connect two or more computers or networking devices in a network, network cables are used.

There are three types of network cables; coaxial, twisted-pair, and fiber-optic. This cable contains a conductor, insulator, braiding, and sheath. The sheath covers the braiding, braiding covers the insulation, and the insulation covers the conductor.

This shield protects signals from external interference and noise. This shield is built from the same metal that is used to build the core. Insulation protects the core. It also keeps the core separate from the braided-shield. Since both the core and the braided-shield use the same metal, without this layer, they will touch each other and create a short-circuit in the wire. The conductor carries electromagnetic signals. Based on conductor a coaxial cable can be categorized into two types; single-core coaxial cable and multi-core coaxial cable.

A single-core coaxial cable uses a single central metal usually copper conductor, while a multi-core coaxial cable uses multiple thin strands of metal wires. The following image shows both types of cable. The coaxial cables were not primarily developed for the computer network. These cables were developed for general purposes. They were in use even before computer networks came into existence. They are still used even their use in computer networks has been completely discontinued.

At the beginning of computer networking, when there were no dedicated media cables available for computer networks, network administrators began using coaxial cables to build computer networks. Because of low-cost and long durability, coaxial cables were used in computer networking for nearly two decades 80s and 90s.

Coaxial cables are no longer used to build any type of computer network. Coaxial cables have been in use for the last four decades. During these years, based on several factors such as the thickness of the sheath, the metal of the conductor, and the material used in insulation, hundreds of specifications have been created to specify the characteristics of coaxial cables.

From these specifications, only a few were used in computer networks. The following table lists them. The twisted-pair cable was primarily developed for computer networks. This cable is also known as Ethernet cable. Almost all modern LAN computer networks use this cable. This cable consists of color-coded pairs of insulated copper wires. Every two wires are twisted around each other to form pair.

Usually, there are four pairs. Each pair has one solid color and one stripped color wire. Solid colors are blue, brown, green and orange. In stripped color, the solid color is mixed with the white color. In the UTP Unshielded twisted-pair cable , all pairs are wrapped in a single plastic sheath. In the STP Shielded twisted-pair cable , each pair is wrapped with an additional metal shield, then all pairs are wrapped in a single outer plastic sheath.

Twisted-pair cabling. This tutorial explains how the twisted-pair cable works and how it is used to connect different networking devices in a network. Since then, these standards have been continually revised to cover the latest technologies and developments of the transmission media. The following table lists the most common and popular categories of the twisted-pair cable. This cable consists of core, cladding, buffer, and jacket.

The core is made from the thin strands of glass or plastic that can carry data over the long distance. The core is wrapped in the cladding; the cladding is wrapped in the buffer, and the buffer is wrapped in the jacket.

This cable can transmit data over a long distance at the highest speed. It can transmit data up to 40 kilometers at the speed of Gbps. Fiber optic uses light to send data. It reflects light from one endpoint to another.

Based on how many beams of light are transmitted at a given time, there are two types of fiber optical cable; SMF and MMF. This cable carries only a single beam of light.

This is more reliable and supports much higher bandwidth and longer distances than the MMF cable. This cable uses a laser as the light source and transmits or nano-meter wavelengths of light. This cable carries multiple beams of light. Because of multiple beams, this cable carries much more data than the SMF cable. This cable is used in shorter distances.

This cable uses an LED as the light source and transmits or nano-meter wavelengths of light. In the next part of this article, we will understand the types of connectors that are used to connect cables with networking devices. We do not accept any kind of Guest Post.

Network Cable Types and Specifications This tutorial explains the types of network cables used in computer networks in detail. RG-8 50 10 Solid copper Used in the earliest computer networks. This cable was used as the backbone-cable in the bus topology. In Ethernet standards, this cable is documented as the 10base5 Thicknet cable. RG 50 24 Several thin strands of copper This cable is thinner, easier to handle and install than the RG-8 cable.

This cable was used to connect a system with the backbone-cable. In Ethernet standards, this cable is documented as the 10base2 Thinnet cable. RG 75 20 - 22 Solid copper Used in cable networks to provide short-distance service. To learn how twisted-pair cables are used in the LAN network, you can check this tutorial. Twisted-pair cabling This tutorial explains how the twisted-pair cable works and how it is used to connect different networking devices in a network.

This cable was used in the telephone network for voice transmission. This cable was used in the token-ring network.

It also uses a fire-resistant plastic sheath. This cable also potentially removes the length limit. This is the recommended cable for all modern Ethernet LAN networks.

This cable uses multiple twisted-pairs and shields each pair by its own plastic sheath. How to configure IPv6 address in Windows. Used in the earliest computer networks. This cable is thinner, easier to handle and install than the RG-8 cable. This cable contains only two pairs 4 wires. This cable and all further cables have a minimum of 8 wires 4 pairs. This cable uses a plastic core to prevent cross-talk between twisted-pair.

This cable reduces attenuation and cross-talk. This cable sets a base for further development.

Cables in Networking, Types and Specifications

Before we dicuss Networking cables, let us know What actually Networking is? The network is the interconnection of the different systems and devices. In our daily life, we consist of a bunch of devices like desktop systems, mobile devices, laptops, Ipads, etc. All these are interconnected to each other to share, receive, and retrieve the information from the devices. We can send work to a printer, print the copy, send a streaming video to the other system user and we can also use it to share the internet connection. To communicate with all these devices, we need a connector to connect between the devices is called a cable.

As Ethernet systems provide increasingly flexible and cost-effective ways of transmitting voice, data, and multimedia over integrated networks, Ethernet patch cords are fast becoming a familiar part of our everyday experience. We can see them in the work areas of commercial and educational buildings as they trail away from the backs of computers to wall plates and other computers. If we follow their trail, we can see them snake along the paths leading from wall plates to patch panels, and then sprout up again from patch panels to meet nearby hubs or switches. But while the modular characteristics and abundance of patch cables seem to imply that their use is completely universal, they do have some important differences among them that can limit their interchangeability. Some of these differences stem from variations in the wiring configurations of their cable conductors and connector pins, and these are the differences that will be discussed here.

Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers , scanners etc. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's physical layer , topology , and size. The devices can be separated by a few meters e. There are several technologies used for network connections. Patch cables are used for short distances in offices and wiring closets.
