In this chapter, we’ll take a look at what you will need to know about cable connections and termination for the Network exam. When working in the field of networking, it’s nearly impossible to not come across physical cabling. Unless you have wireless media (covered in Chapter 4), you will need some form of cabling, and need some form of endpoint, or termina-tion, to your transmission media and a way for it to physically connect to a device.This endpoint is called a connector, and it terminates the end of the media, creating a way for it to connect to something else such as a patch panel, switch port, or other connection. This chapter shows you what you need to know about connecting and terminating the most common forms of cable in use today: twisted-pair cabling, coaxial cabling, and fiber optics. The understanding of transmission media types, connectors, and termination is essential to being a networking professional. In this chapter, we will learn the fundamentals of cabling, the connectors used with them, and the most common tools of the trade.45
