Example text

The improvements Cat6 allow also increase reliability. , it will work in a Cat5e system. Figure 2-36 Figure 2-37 Cat5e cable and a Cat6 connectors and plugs cable are made the same way and the wireing order is the same. Only one tool is needed to make a jack, a Cat5/Cat6 crimping tool (item 1 in Figure 2-36). A Cat5e/Cat6 cable stripper (item 3 of Figure 2-36) is nice to have but not absolutely necessary. To make a RJ-45 plug, a punch down tool is needed (item 2 in Figure 2-36). 3-2001. The styles are 568A and 568B wiring hierarchies.

You may want to read and practice the material on soldering in Chapters 3 and 4. Start by stripping at least 5/8” (16 mm) of insulation off each wire ( Figure 2-10a). 5 mm) required of a properly made mesh splice. When the ends have been joined, flatten the wires and leave a solder gap as shown in Figure 2-10b. Finally, solder (Figure 2-10c) the connection and heat shrink to insulate and protect the splice. Figure 2-10b Figure 2-10c Figure 2-11a Figure 2-11b Crimping Tools and Splicing The Lap Splice The Lap splice will work for solid and stranded wire.

Familiarize yourself with the tool before you use it. The punch down has two functions, to force the wires into the jacks connectors, and to cut the excess wire. One side of the tool tip has a cutting edge to trim the excess wire. This cutting side, seen in Figure 2-44, should be on the outside of the jack when the tools is used.
