Sample text

Be sure to maintain proper solder gaps while doing this. Heat shrink can be used on a tap splice (Chapter 4). If heat shrink is used, bend the Figure 2-10a tapped wire parallel to the original run and solder the connection. The Mesh Splice The mesh splice is used to join stranded wires end to end. Soldering is required for this splice (and the lap splice, which follows). 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).

This separator keeps the wires in a specific position and is the feature which extends the frequency capability of Cat6 cables. In each cable, two wires are wrapped around one another to form a twisted pair. The pairs are: 1)green/green and white, 2)blue/blue and white, 3) brown/ brown and white and, 4) orange/orange and white. Figure 2-34 is a Cat6 cable. The white strands at the bottom ofwhite strands at the bottom of 33 and 2-34 are thin nylon cords. Twisted pair are used because they improve signal quality via complementary signals.

The connection can now be tested. Figure 2-24 Figure 2-25 This is only one style of connector among the hundreds that are available. No matter the type you work with, always: 1) have the data sheet for the connector available, 2) never damage any part of the RF cable, particularly the shield and center wire, 3) do not distort the inner insulator by crimping the sleeve too hard, 4) be sure the center pin extends out sufficiently but not too far. Figure 2-26 This is a commercially available RF cable stripper.
