For TA, the color order of the 8 pins are white, green, white orange, blue, white blue, orange, white brown, and brown from pin 1 to pin 8 respectively. While, in TB wiring standard, there are two color order exchanges compared with TA, pin 1 in exchange for Pin 3 and pin 2 in exchange for Pin 6. Straight through cable uses the same wiring standard on both ends. That is, both ends connector A and connector B use TA wiring standard or both ends use TB wiring standard with the same color.
Crossover cable such as Cat5, Cat5e crossover cable, etc. Different from the straight-through Ethernet cable, crossover network cable uses two different wiring standards on both ends connector A and connector B. One end uses the TA wiring standard, and the other end uses the TB wiring standard. This type of cable is typically used for direct computer-to-computer connections. The following section will introduce the straight through cable or patch cable and crossover cable in details. Many networking professionals use the term patch cable to refer to any kind of straight through cable.
So a patch cable is often called a straight through cable. In other words, patch cable does not change or swap along its way. Both ends use the same wiring standard: TA or TB. So both side connector A and connector B of patch cable have wire arrangement with same patch cable colors as shown in the following picture.
These patch cables are widely used for connecting the computer to the switches, hubs, or routers. Crossover cable, as the name suggests, cross over or swap on its way when coming from one end to the other. Unlike patch cable, crossover cable uses two different wiring standards on both end: one end uses the TA wiring standard, and the other end uses the TB wiring standard.
Both side connector A and connector B of crossover cable have wire arrangement with different color, and the wires that come out of the connector A should match the correct pin at the connector B.
As shown in the following wiring scheme, you can see that Pin 1 on connector A goes to Pin 3 on connector B, pin 2 to pin 6, pin 3 to pin 1 and pin 6 to pin 2, etc. The crossover cables are mainly used for connecting two routers, computers, or hubs. In brief, a crossover cable connects two devices of the same type to communicate together, like a PC to a PC, or a switch to a switch. The patch cable connects two different devices to each other, like a PC and a switch.
The functions of these cables certainly do differ, but the crossover cable is essentially a derivative of the original straight-through version. To find out more about our selection of Ethernet cables, please contact us today. You must be logged in to post a comment. Connect With Us.
