- 5. WHAT IS NETWORK CABLING Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.

- 7. (1) COAXIAL CABLE Coaxial cable is commonly used by cable operators, telephone companies, and internet providers around the world to convey data, video, and voice communications to customers. It has also been used extensively within homes. Coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by a conductive shielding. Many also have an insulating outer jacket The diagram below illustrates the construction of a typical cable. Electrical signal flows through 1. Center Conductor 2. Center Conductor bond 3.

- 8. (1) COAXIAL CABLE The most common type of connector used with coaxial cables is the Bayone-Neill- Concelman (BNC) connector. To help avoid problems with your network, always use the BNC connectors that crimp, rather screw, onto the cable.
- 9. (2) TWISTED PAIR Twisted pair cabling comes in two varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks
- 10. (2) TWISTED PAIR The quality of UTP may vary from telephone-grade wire to extremely high-speed cable. The cable has four pairs of wires inside the jacket. Each pair is twisted with a different number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices. The tighter the twisting, the higher the supported transmission rate and the greater the cost per foot. The EIA/TIA (Electronic Industry Association/Telecommunication Industry Association) has established standards of UTP and rated eight categories of wire as shown in the next slide.

- 12. (2) TWISTED PAIR Cable type and its specification
- 13. (2) TWISTED PAIR CATEGORY CABLE SHIELDING The acronyms used to describe the cable shielding have changed over the last several years in order to avoid confusion of the different types of shielding found on Category cables today. The mechanical construction of the Category cables shielding is identified by specific abbreviations. These abbreviations or acronyms were established by the ISO/IEC 11801 standard and adopted by TIA/EIA. The standard abbreviations are as follows: TP = Twisted Pair U = Unshielded F = Foil Shield S= Braided Shield Example:F/UTP F: Describes the overall shielding type U: Describes the shielding of the pairs TP: Describes the Twisted Pairs The code before the slash describes the overall shielding. The second letter after the slash describes the shielding of the individual pairs.

- 15. (3) FIBER OPTIC CABLE Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials. It transmits light rather than electronic signals eliminating the problem of electrical interference. This makes it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between buildings, due to its immunity to the effects of moisture and lighting.
- 16. (3) FIBER OPTIC CABLE The number of mobile internet users and the proliferation of connected devices have led to the exponential growth in global internet traffic. These traffic will make more network providers to upgrade their networks and introduce more optical assemblies like fiber optic cables, fiber optic connector, fiber optic transceiver, etc.
- 17. (3) FIBER OPTIC CABLE Fiber optic connector types are as various as the applications for which they were developed. Different connector types have different characteristics, different advantages and disadvantages, and different performance parameters. But all connectors have the same three basic components: ferrule, connector body, cable, coupling device.
- 18. (3) FIBER OPTIC CABLE Ferrule: the ferrule acts as a fiber alignment mechanism and holds the glass fiber. It has a hollowed-out center that forms a tight grip on the fiber. Ferrules are typically made of metal, ceramic or quality plastic. Connector Body: also known as the connector housing, the body holds the ferrule and attaches to the jacket and strengthens members of the fiber cable itself. It is usually constructed of metal or plastic and includes one or more assembled pieces which hold the fiber in place. Coupling Device: coupling device is a part of the connector body that keeps the connector in place when attached to another device like as bulkhead coupler and optical transceiver.
