Objectives

Objectives:

  • Determine which type of cabling is best for any networking situation.

  • Identify the primary types of network cabling.

After this lesson, you will be able to:


What is network cabling

What is Network Cabling?

  • is the medium through which information usually moves from one networkdevice to another. There are several types of cable which are commonly used withLANs. In some cases, a network will utilize only one type of cable, other networkswill use a variety of cable types.


Network cabling and wireless network

  • The type of cable chosen for a network isrelated to the network's topology, protocol, and size. Understanding thecharacteristics of different types of cable and how they relate to other aspectsof a network is necessary for the development of a successful network.


Types of cables used in networks

Types of cables used in Networks

Unshielded Twisted Pair (UTP) Cable

Shielded Twisted Pair (STP) Cable

Coaxial Cable

Fiber Optics Cable


Unshielded twisted pair utp cable

Unshielded Twisted Pair (UTP) Cable

Twisted pair cabling comes in two varieties: shielded and unshielded. Unshieldedtwisted pair (UTP) is the most popular and is generally the best option for schoolnetworks.

RJ45


Advantages

Advantages

  • Fastest copper-based medium available.

  • Less expensive than STP cables, costing less per meter than other types of LAN cabling.

  • Have an external diameter of approximately .43 cm, making it a smaller cable than STP cable and easier to work with during installation, as it doesn't fill the wiring ducts as fast as other cables.


Disadvantages

Disadvantages

  • Susceptible to radio frequency interference (RFI) and electromagnetic interference (EMI) such as is caused from the microwave.

  • More prone to electronic noise and interference than other forms of cable

Categories of Unshielded Twisted Pair (UTP) Cable


Shielded twisted pair utp cable

Shielded Twisted Pair (UTP) Cable

a type of copper telephone wiring in which each of the two copper wires that are twisted together are coated with an insulating coating that functions as a ground for the wires. The extra covering in shielded twisted pair wiring protects the transmission line from electromagnetic interference leaking into or out of the cable.

Shielded Twisted Pair (UTP) Cable


Advantages1

Advantages

  • Less susceptible to electrical interference caused by nearby equipment or wires.

  • Less likely to cause interference themselves.

  • Faster speed in carrying data.


Disadvantages1

Disadvantages

  • Physically larger.

  • More expensive than twisted pair wire

  • More difficult to connect to a terminating block.


Coaxial cable

Coaxial cable

  • Coaxial cabling has a single copper conductor at its center. A plastic layerprovides insulation between the center conductor and a braided metal shield.

  • The metal shield helps to block any outside interference from fluorescentlights, motors, and other computers.


Two types of coaxial cable

Two types of coaxial cable

  • Thick coaxial

Coaxial cable connector

Coaxial Cable Connector

  • The most common type of connector used with coaxial cables is the Bayone-Neill-Concelman (BNC) connector.

  • Different types of adapters are availablefor BNC connectors, including a T-connector, barrel connector, and terminator.

Advantages of coaxial

Advantages of coaxial

  • They are cheap to make

  • Cheap to install

  • Easy to modify

  • Good bandwith

  • Great channel capacity

  • Noise immunity due to low rate


Disadvantages of coaxial

Disadvantages of coaxial

  • More expensive than twisted pairs

  • Not supported for some network standards (eg. token ring)

  • Its also very bulky and also has high attenuation so would have the need to implement repeaters.


Fiber optic cable

Fiber Optic Cable

  • Consists of a center glass core surrounded by several layersof protective materials.

  • It transmits light rather than electronicsignals eliminating the problem of electrical interference.

Advantages2

Advantages

  • System Performance .

  • Greatly increased bandwidth and capacity.

  • Immunity to Electrical Noise

  • Freedom from short circuit and sparks.


Disadvantages2

Disadvantages

  • Expensive to install and the equipment is expensive.

  • Lack of standardization globally and some locally which makes companies hesitant to use it.

  • Cannot carry power like telephone and other electrical signals can.

Wireless network

Wireless Network

  • Utilize radio waves and/or microwaves to maintain communication channels between computers. Wireless networking is a more modern alternative to wired networking that relies on copper and/or fiber optic cabling between network devices.


Network cabling and wireless network

  • Rapidly gaining in popularity for both home and business networking. Wireless technology continues to improve, and the cost of wireless products continues to decrease.


Network cabling and wireless network

  • Popular wireless local area networking (WLAN) products conform to the 802.11 "Wi-Fi" standards. The gear a person needs to build wireless networks includes network adapters (NICs), access points (APs), and routers.

Advantages3

Advantages

  • Easy to add stations as there are no cables required.

  • Signals can be sent through doors and walls so the stations can be mobile so can move around.

  • There is less need for technical support in setting up due to their simple nature.


Network cabling and wireless network

  • There are no cables to trip over so there are less health and safety issues to consider share resources like printers. Have shared access to a centralized storage.


Disadvantages3

Disadvantages

  • Signals can suffer from other signals.

  • To access the networks, you have to be within a certain range.


Network cabling and wireless network

  • The wireless networks can be quite slow.

  • It is easy for hackers to hack or catch the signal.
