What is a CAT5 crossover cable used for?
Crossover cable such as Cat5, Cat5e crossover cable, etc. is a type of twisted pair cable used to connect two devices of the same type such as “DTE to DTE” or ”DCE to DCE” in the following situations: One computer to another computer. One switch to another switch connecting a normal port on both sides.
What is CAT 5 crossover?
Cat-5 is just the name given to cables with four wire pairs that each meet the “Category 5” specification for data communications. In addition to crossover cables, which are designed for networking two like devices (e.g. computer-to-computer or hub-to-hub), Cat-5 cables can also be made in what’s known as patch cables.
Why would you use a crossover cable?
You should use a crossover cable when you want to connect two devices of the same type. It helps you connect a router’s WAN port to a cable or DSL modem’s LAN port. You can connect two switches/hubs by using the normal port in both switches/hubs. Straight-through cables are mainly used for connecting, unlike devices.
Are crossover cables still needed?
Crossover cables are still needed in one specific scenario – to connect devices that aren’t outfitted with Gigabit Ethernet functionality. This is a high-quality, high-speed standard found in most but not all modern devices that support Ethernet.
Are crossover cables needed anymore?
Though not obsolete, crossover cables are no longer as common as they used to be, and in almost all cases, a standard Ethernet cable can be used for the same purpose.
How do I know if my Ethernet cable is crossover?
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. If not, then it’s most likely a crossover cable or was wired wrong.
Do you need a crossover cable to connect two routers?
A straight-through cable is used in local area networks to connect different devices like a computer to a network hub such as a router, router and switch, PC and switch, and so on. A crossover cable is only required when interconnecting two devices with the same functionality.
Do modern laptops need crossover cables?
The answer is simple: You don’t need such cable.
Can you connect two computers with a straight-through cable?
Yes, If both of the Computers have NICs (Network Interface Cards) with Auto MDIX (Medium Dependent Interface Crossover) capability then Straight Cable can be used to connect similar network devices, i.e. A Computer to Another Computer instead of a Crossover Cable required.
When to use a crossover cable?
A crossover cable is a cable that is used to interconnect two computers by “crossing over” (reversing) their respective pin contacts. Either an RS-232C or a telephone jack connection is possible. A crossover cable is sometimes known as a null modem.
How do you make a crossover cable?
If you are creating a crossover cable, please click here for the crossover cable diagram. Using a cable stripping tool, strip about 1/3″of the out jacket of the cat-5 cable. Assemble the pairs of wires in the following order for network cables (EAI standard / TIA-568B). Insert the wires into the RJ45 jack as seen below.
Are there different quality Cat5 cables?
Category 5 (Cat-5) and Category 5 enhanced (Cat-5e) are actually basically the same . Nothing changed physically in the cable itself. Instead, Cat-5e cables are tested more stringently to ensure less crosstalk (electrical interference). In other words, only some of those old Cat-5 cables are good enough to be Cat-5e cables.
What is the wire order for Cat 5 cable?
CAT-5 Wire Pairs. The four wire pairs in a CAT-5 cable are distinguished by the color of their insulation. The four colors are (in order) blue, orange, green and brown. Thus, when refering to the “second pair” of wires, it is the orange pair.
