UTP s internal copper cables are either 22- or 24-gauge in diameter UTP for Ethernet has 100-ohm impedance, so you can t use just any UTP wiring, like that commonly found for telephones, for example Each of the eight wires inside the cable is colored: some solid, some striped Two pairs of the wires carry a true voltage, commonly called tip (T1 T4), and the other four carry an inverse voltage, commonly called ring (R1 R4) Today, people commonly call these positive and negative wires, respectively A pair consists of a positive and negative wire, such as T1 and R1, T2 and R2, and so on, where each pair is twisted down the length of the cable
UTP Categories To help differentiate between the different kinds of UTP cabling, different categories were created Table 3-8 shows the categories of UTP cabling
TABLE 3-8
Category
Category 1 Category 2 Category 3 Category 4 Category 5 Category 5E Category 6
Description
Used for telephone connections (not suitable for data) Used for data connections up to 4 Mbps Token Ring Used for data connections up to 10 Mbps Ethernet 10BaseT Used for data connections up to 16 Mbps Token Ring Used for data connections up to 100 Mbps Ethernet Used for data connections up to 1 Gbps (gigabit per second) Ethernet Used for data connections up to 1 Gbps (24-gauge) Ethernet
UTP Categories
3: Layer 2 LAN Technologies
The two endpoints of a UTP cable have an RJ-45 connector The RJ-45 connector is a male connector that plugs into a female RJ-45 receptacle The RJ-45 connector is similar to what you see on a telephone connector (RJ-11), except that the RJ-45 is about 50 percent larger in size
Cabling Devices With today s implementation of Ethernet over copper, two components make up the connection: an RJ-45 connector and a Category 5, 5E, or 6 UTP cable As mentioned earlier, the UTP cable has eight wires in it (four pairs of wires) Two types of implementations are used for the pinouts of the two sides of the wiring: straight-through and crossover Pinout refers to the color of wire used in the cables and pins in a particular position of the RJ-45 interface Two standards define the cabling pinouts: 568B is used for both straight-through cables and one end of a crossover cable 568B wiring colors are listed in Table 3-9 A straight-through Ethernet UTP cable has pin 1 on one side connected to pin 1 on the other side, pin 2 to pin 2, and so on A straight-through cable is used for DTE-to-DCE (data termination equipment to data communications equipment) connections The terms DTE and DCE are typically used in WAN connections, where the DCE provides clocking These terms will be discussed in more depth in 25 However, in LAN terms, a DTE is a router, PC, or file server, and a DCE is a hub or a switch Here is when you should use a straight-through Ethernet cable, as is shown in Figure 3-3:
A hub to a router, PC, or file server A switch or bridge to a router, PC, or file server
