网线分为直通网线(Straight through cable)和交叉网线(Crossover cable)两种: 直通网线:两端RJ45接头压接的双绞线的线序完全相同,用于不同设备之间的互连,如PC与交换机之间的连接。 交叉网线:两端RJ45接头压接的双绞线的线序不相同,用于相同设备或相同接口之间的互连,如PC与PC之间的连接。
The straight-through cable and the crossover cable have the same appearance and use the RJ45 connector. Figure 8-16 shows the appearance of an Ethernet cable. Figure 8-16 Appearance of an Ethernet cable Figure 8-17 shows the structure of an Ethernet cable. Figure 8-17 Structure of an Ethe...
In the Ethernet cable pinout there are basically two cables: (1) the straight cable and (2) the crossover cable. The cables are color coded. It is very important to connect the cables properly because improperly connected cables can lead to loss of Internet connectivity. The straight cables ...
Straight-through and Cross-over Connections The wiring standards T568A and T568B are used to create a cross-over cable (T568A on one end, and T568B on the other end), or a straight-through cable (T568B or T568A on both ends). Straight-through cables are used to connect computers...

An Ethernet switch can be thought of as a device that makes temporary crossover cable connections between computers that want to communicate. Just like crossover cables, switches do not suffer from collision problems. However, it should be noted that the actual cables used are “straight through...
