- 4. LEARNING OBJECTIVES • Understand the basics of network cabling and its importance in networking. • Identify different types of network cables and their characteristics. • Recognize the development of new network cable technologies and their significance in modern networking.
- 5. NEW LESSON Types of network cables: An IntroductionTo Network Cabling
- 6. INTRODUCTION Different types of networking cables are the backbone of a network's infrastructure. Selecting the right type is critical, as enterprise network administrators deploy new technologies. Network services, like file sharing, internet access, network printing, email, ERP systems and more, are all delivered to end users via the network infrastructure, which usually includes switches, fiber optic links and, underpinning it all, unshielded twisted pair (UTP) cabling.
- 7. DEVELOPMENT OF NEW NETWORK CABLE TECHNOLOGY Ethernet was developed in the mid-1970s by Robert Metcalfe and David Boggs at Xerox Corp. at its Palo Alto Research Center in California. In 1979, DEC and Intel joined forces with Xerox to standardize the Ethernet system.The first specification by the three companies, called the Ethernet Blue Book, was released in 1980; it was also known as the DIX standard after the company's initials. In 1983, the IEEE released the official Ethernet standard. It was called IEEE 802.3, after the name of the working group responsible for its development; in 1985, version 2 (IEEE 802.3a) was released.
- 8. TYPES OF CABLES UnshieldedTwisted Pair (UTP) • UTP cable is certainly the most popular type of network cable by far around the world. • It is used not only for networking, but also for the traditional telephone (UTP-CAT1). • There are six different types of UTP categories and, depending on what you want to achieve, you would need the appropriate type of network cable. • UTP-CAT5e is the most popular UTP cable; it replaced the old coaxial cable that was unable to keep up with the constantly growing need for faster and more reliable networks.
- 9. CHARACTERISTICS OF UTP CATEGORIES
- 10. CHARACTERISTICS OF UTP CATEGORIES The characteristics of UTP are very good and make it easy to work with, install, expand and troubleshoot.
- 11. TYPES OF CABLES ShieldedTwisted Pair (STP) • Shielded Twisted Pair (STP), like UTP, also has four pairs of wires with each wire in each pair twisted together. • However, the difference is that STP is surrounded with a foil shield and copper braided around the wires that allows more protection from any external electromagnetic interference. • Because of the shielding, the cable is physically larger, more difficult to install and terminate, and more expensive than UTP.
- 12. TYPES OF CABLES Coaxial Cable • Coaxial cable is braided-grounded strands of wire that can provide some shielding and noise immunity; • however, the installation and the termination of the cable itself can be costly. • Coaxial cabling, which uses connectors called BNC (Bayonet Nut Connector) is known as, in forms of Ethernet, in the older LAN technology, and cableTV.
- 13. TYPES OF CABLES
- 14. TYPES OF CABLES Fiber Optic • Fiber optic cabling carries signals, which have been converted from electrical to optical (pulses of light) form. • It consists of the core, either an extremely thin cylinder of glass or optical quality plastic, which is surrounded by a second glass or plastic layer called the cladding. • The interface between the core and cladding can trap light signals by a process called Total Internal Reflection (TIR), resulting in the optical fiber acting as a light pipe.
- 15. TYPES OF CABLES
- 16. TYPES OF CABLES Fiber Optic • Fiber optic cables are not susceptible to interference, such as radio waves, fluorescent lighting, or any other source of electrical noise. • It is the common cable used for network backbones and can support up to 1000 stations, carrying signals beyond 25 km.
