An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type, e.g. two computers (via their network interface controllers) or two switches to each other. By contrast, straight throughpatch cables are used to connect devices of different types, such as a computer to a network switch.
You can start a crossover cable with either standard as long as the other end is the other standard. It makes no functional difference which end is which. Despite what you may have read elsewhere, a 568A patch cable will work in a network with 568B wiring and 568B patch cable will work in a 568A network. The electrons couldn’t. As there are fault occurrences in straight-through cable crossover cable came into exists. The drawback is drawn when two PC’s want to connect, transmit, and to listen. Eg, when pc-1 and pc-2 are connected with a straight-through cable. This will be followed be green, white/orange, blue, white/blue, orange, white/brown, brown. NOTE: Once again, on the crossover cable the ends will be different. If you have a cable tester, it can also verify your cable as being either a patch or crossover. A patch cable plugged into a test will read 12345678. A crossover cable will read 36145278.

Intentionally crossed wiring in the crossover cable connects the transmit signals at one end to the receive signals at the other end.
Many network devices today support auto MDI-X capability, wherein a patch cable can be used in place of a crossover cable, or vice versa, and the receive and transmit signals are reconfigured automatically within the device to yield a working connection.Motivation[edit]8P8C modular crossover adapter
The 10BASE-T and 100BASE-TX Ethernet standards use one wire pair for transmission in each direction. This requires that the transmit pair of each device be connected to the receive pair of the device on the other end. The 10BASE-T standard was devised to be used with existing twisted pair cable installations with straight-through connections.
When a terminal device (with an MDI port) is connected to a switch or hub, this crossover is done internally in the switch or hub (MDI-X port). A standard straight-through cable is used for this purpose where each pin of the connector on one end is connected to the corresponding pin on the other connector.
One terminal may be connected directly to another without the use of a switch or hub, but in that case, the crossover must be done in the cabling. Since 10BASE-T and 100BASE-TX use pairs 2 and 3, these two pairs must be swapped in the cable. This wiring scheme constitutes a crossover cable. A crossover cable may also be used to connect two hubs or two switches on their upstream ports.
Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring). Such a cable will work for 10BASE-T or 100BASE-TX.
The polarity of each pair is not swapped, but the pairs crossed as a unit: the two wires within each pair are not crossed.[1]Cable requirement for Ethernet linkToMDIMDI-XAuto MDI-XMDIcrossoverstraightanyMDI-XstraightcrossoveranyAuto MDI-XanyanyanyAutomatic crossover[edit]
Introduced in 1998, this made the distinction between uplink and normal ports and manual selector switches on older hubs and switches obsolete.[2] If one or both of two connected devices has the automatic MDI/MDI-X configuration feature, there is no need for crossover cables.Download Free Patch Cable Crossover Cable Same Software Downloads
Although Auto MDI-X was specified as an optional feature in the 1000BASE-T standard,[3] in practice it is implemented widely on most interfaces.
Besides the eventually agreed upon Automatic MDI/MDI-X, this feature may also be referred to by various vendor-specific terms including: Auto uplink and trade, Universal Cable Recognition and Auto Sensing.1000BASE-T and faster[edit]
In a departure from both 10BASE-T and 100BASE-TX, 1000BASE-T and faster use all four cable pairs for simultaneous transmission in both directions through the use of telephone hybrid-like signal handling. For this reason, there are no dedicated transmit and receive pairs. 1000BASE-T and faster require either a straight or one of the crossover variants only for the autonegotiation phase. The physical medium attachment (PMA) sublayer provides identification of each pair and usually continues to work even over cable where the pairs are unusually swapped or crossed.[4]Fiber[edit]
For most optical fiber variants of Ethernet, fibers are used in pairs with one fiber for each direction. The transmitter on one end of the connection needs to be connected to the receiver on the other and vice versa. For this, fiber patch cables with duplex connectors are normally configured as crossover as is the on-premises wiring.[citation needed] Thus, a simple connection with two patch cables at each end and a section of fixed cable in the middle has three crossovers in total, resulting in a working connection. Patch cable crossovers can usually be reconfigured very easily by swapping the connectors within a duplex bracket if required.Pinouts[edit]
In practice, it does not matter if non-crossover Ethernet cables are wired as T568A or T568B, just so long as both ends follow the same wiring format. Typical commercially available ’pre-wired’ cables can follow either format depending on the manufacturer. What this means is that one manufacturer’s cables are wired one way and another’s the other way, yet both are correct and will work. In either case, T568A or T568B, a normal (un-crossed) cable will have both ends wired identically according to the layout in either the Connection 1 column or the Connection 2 column.Half crossed[edit]Crossover cable connecting two MDI ports
Certain equipment or installations, including those in which phone and/or power are mixed with data in the same cable, may require that the ’non-data’ pairs 1 and 4 (pins 4, 5, 7 and 8) remain un-crossed. This is the most common kind of crossover cable.Two pairs crossed, two pairs uncrossed 10BASE-T or 100BASE-TX crossover[5]PinConnection 1: T568AConnection 2: T568BPins on plug facesignalpaircolorsignalpaircolor1BI_DA+3white/green stripeBI_DB+2white/orange stripe2BI_DA-3green solidBI_DB-2orange solid3BI_DB+2white/orange stripeBI_DA+3white/green stripe41blue solid1blue solid51white/blue stripe1white/blue stripe6BI_DB-2orange solidBI_DA-3green solid74white/brown stripe4white/brown stripe84brown solid4brown solidFully crossed[edit]All pairs crossedWhile this is the only crossover for 1G, it also works for 10M and 100M ethernetPinTIA/EIA 568-ATIA/EIA 568-BNormalCrossoverNormalCrossover1white/green stripewhite/orange stripewhite/orange stripewhite/green stripe2green solidorange solidorange solidgreen solid3white/orange stripewhite/green stripewhite/green stripewhite/orange stripe4blue solidwhite/brown stripeblue solidwhite/brown stripe5white/blue stripebrown solidwhite/blue stripebrown solid6orange solidgreen solidgreen solidorange solid7white/brown stripeblue solidwhite/brown stripeblue solid8brown solidwhite/blue stripebrown solidwhite/blue stripeDownload Free Patch Cable Crossover Cable Same Software DownloadSee also[edit]References[edit]
