3.2.3: Backbone cabling between wiring closets is called vertical cabling. Horizontal cabling refers to the cables used to connect hosts and devices in the work area to the wiring closet. Consider the following points about each type of cable when you design your network’s physical topology:
• Shielded twisted pair (STP) has foil shielding to protect from outside EMI and can be run for only 100 meters. STP can be Category 5, 5e, or 6 cable.
• Unshielded twisted pair (UTP) has no shielding and is also limited to 100 meters; however, UTP is inexpensive.
• Coaxial provides a shielded solid copper core for transmission and is not as limited by distance as UTP or STP.
• Fiber-optic cable is not affected by EMI, can run ...
