Network media types

You can see in Table 2.

Network media types

There are three common types of cable media that can be used to connect devices to a network and they are coaxial cable, twisted-pair cable, and fiber-optic cable. Coaxial cable Coaxial cable looks similar to the cable used to carry TV signal.

A solid-core copper wire runs down the middle of the cable. Around that solid-core copper wire is a layer of insulation, and covering that insulation is braided wire and metal foil, which shields against electromagnetic interference.

A final layer of insulation covers the braided wire.

There are two types of coaxial cabling: Thinnet is used for short-distance. The maximum length of thinnet is meters. Thicknet coaxial is thicker cable than thinnet. Thicknet has a maximum cable length of meters and usually is used as a backbone to connect several smaller thinnet-based networks.

The bandwidth for coaxial cable is 10 Mbps Mega bits per second. It is extremely difficult to find a live business network using coaxial cable. A pair of wires forms a circuit that can transmit data. The pairs are twisted to provide protection against crosstalk.

Crosstalk is the undesired signal noise generated by the Electro-Magnetic fields of the adjacent wires. When a wire is carrying a current, the current creates a magnetic field around the wire.

This field can interfere with signals on nearby wires. To eliminate this, pairs of wires carry signals in opposite directions, so that the two magnetic fields also occur in opposite directions and cancel each other out.

This process is known as cancellation. Unshielded twisted-pair UTP cable is the most common networking media. Unshielded twisted-pair UTP consists of four pairs of thin, copper wires covered in color-coded plastic insulation that are twisted together.

The wire pairs are then covered with a plastic outer jacket. Since there is no shielding for UTP cabling, it relies only on the cancellation to avoid noise.

Following image shows a dissected Unshielded Twisted Pair cable. Eight color-coded wires inside Twisted-Pair cable is attached to eight pins in a RJ45 jack as shown below. Each wire in the Twisted Pair cable is crimped into 8 pins in the RJ45 jack.

UTP cabling has different categories. Each category of UTP cabling was designed for a specific type of communication or transfer rate. The most popular categories in use today is 5e and 6, which can reach transfer rates of over Mbps 1 Gbps.

The following table shows different UTP categories and corresponding transfer rate.This article takes a look at the LAN network cable media that is typically installed in most environments and the different connectors that are often used.

Cable Media There are a number of different cabling types that a network engineer/administrator sees over the course of their career.

The three types of network media are: Twisted-pair copper cable, fiber-optic cable, and coaxial cable. There are so many different types of computer networks in existence, it can be hard to understand the differences between them, particularly the ones with very similar-sounding names.

Describe the primary types and uses of wireless media Network Media Types Network media is the actual path over which an electrical signal travels as it moves from one component to another. This chapter describes the common types of network media.

Comparing Media Types. Presented in Table are comparisons of the features of the common network media. This chart provides an overview of various media that you can use as a reference.

The medium is possibly the single most important long-term investment made in a network.
