The cables and components used to build a twisted-pair horizontal cable segment are based on the ANSI/TIA-568-C structured cabling specifications, which are designed to support all twisted-pair Ethernet media systems. These specifications are described in Chapter 15.
In this chapter, we’ll show how a twisted-pair cable segment is wired and describe the components that are typically used. You may find this useful even if you don’t build your own horizontal cable segment. Knowing the components and wiring standards used in cable segments can help you make sure that your cabling system is assembled properly. Being able to find your way around a cabling system is also a major benefit when it comes to troubleshooting network problems.
Following the sections on the various components of a twisted-pair cable segment, you’ll learn how to install an RJ45 connector on a twisted-pair patch cable. The chapter concludes with special twisted-pair cabling considerations for the three twisted-pair Ethernet media systems, including the signal crossover wiring required by each system.
A horizontal cable segment is one that travels from a wiring closet to a work area, connecting an Ethernet switch with a station. This is the most widely used cable segment type in a structured cabling system. Building a horizontal twisted-pair segment involves the following set of components and specifications:
