These cables are always used to connect devices to each other. A straight-through cable is also called a catch cable by some professionals, and straight-through cables are the most common ethernet cable that is used. A crossover cable is also an ethernet cable. The difference between a straight-through cable is that it has a different wire sequence between connectors.
With a crossover cable, the configuration of the wires is slightly more complicated. With an ethernet connector, there are 8 pin slots on each side of the cable. The wires will be organized in this order: pin one on side A connects to pin three on side B, pin two on side A connects to pin six on side B, pin three on side A connects pin one on side B, pin four on side A connects to pin seven on side B, pin five on side A connects to pin eight on side B, pin six on side A connects to pin two on side B, pin seven on side A connects to pin four on side B, and pin eight on side A connects to pin five on side B.
There are also set, colored wires that go into each pin slot. With the pin connections woven this way, it creates a system where the wires are overlapping each other. A crossover cable also uses a cat5 cable.
The order of colors in order from pin one to pin eight would be, orange-white, orange, green-white, blue, blue-white, green, brown-white, brown.
Besides the configuration of the wires, there are a number of differences between the two. Comparing straight through vs. The general rule of thumb when it comes to comparing these two wiring types is that straight-through cables are used for dissimilar devices and crossover cables are used for similar devices. Straight-through cables will be used to connect different types of hosts to each other.
This means that whenever you are connecting a computer to a router, a router to a switch, and so on, you will have to use a straight-through cable for the hosts to communicate with each other. For example, with a straight-through cable, two computers would attempt to use the same channel to transmit information, essentially canceling one another out.
This would not be the case with a crossover patch cord. Crossover cables have two different siring standards: TA and TB. TA is preferred since it provides backward compatibility to one pair or two pair wiring configurations. Straight-through cables are mainly used for connecting non-similar devices while crossover cables are mostly used for connecting similar devices. Report a Bug. Previous Prev. Next Continue.

Straight through and crossover cables are wired differently from each other. One easy way to tell what you have is to look at the order of the colored wires inside the RJ45 connector. If the order of the wires is the same on both ends, then you have a straight through cable.
At present, the straight through cable is much more popular than crossover cable and is widely used by people. Look for Ethernet patch cables , just come to FS.
