rollover cable vs crossover cable

Intersection line: One is t-586a standard on the other end is the standard of t-568b can be directly connected to two computers (network card to the network card)Ordinary network cable (straight line) at both ends are generally t-568b standardSo: Need a specially made cable, or have a spare line to change it can also be changed only a head. When making the crystal head, the other end of the 1th and 3rd to s

Production and Application of direct connection network cable and Cross network cable production and application of direct connection network cable and Cross network cable (cross line) one is the standard of the T-586A, the other is the standard of the T-568B can be directly connected to two computers (NIC-to-nic) Ord

The serial cable can be divided into straight chain and intersection. Generally for straight line extension PC equip, will 2, 3, 5 connect 2, 3, 5, because PC universal male. But the devices are mostly female, so they are just plain, and it can also be used to extend the connection; the crossover PC is connected to the PC with 2 pairs of 3, 3 pairs of 2, 5 to 5, and the general two are female at both ends!B

during the hub Cascade, the Cascade control switch should be placed on the MDI (uplink) and connected with a straight line. If the hub does not have a dedicated grade port, or can not use the cascade, you must use the Mdi-x mouth level, at which point, we can be used to achieve the purpose of the crossover line, where the intersection line, that is, when doing network cable, with one end RJ-45 plug 1 feet

affected. After removing the gray plastic protective layer, you can see the 4-to 8-core wires of the twisted pair cable, and the colors of each pair are different. Each pair of core wires is composed of a colored core wire and a white core wire with only a few colors. The four full-color cores are brown, orange, green, and blue. Each pair of wires is intertwined. When creating a network cable, you must u

. The Cabling Standards of twisted pair wires in the network are as follows: (1) One-to-one matching method. That is, the core wires at both ends of the twisted pair must correspond one by one, that is, if the 1st feet at one end are green, the 1st feet at the other end must also be green core wires, the twisted pair wires are usually called "direct connections ". However, it should be noted that the four core wires are normally not separated, that is, the two core wires of the core wires are no

of the reverse line is that the test has been completed and there is no need to worry about the cable length on the rear side of the Cabinet. The disadvantage is that the two ends of the cable have been fixed, and there will be a lot of crossover between the cables. It is very laborious to make the cables neat and tidy, and there must be a pair of twisted wires

available when creating an RJ45 crystal head, when a problem occurs at one end of a cable made by others, you have to look at the line sequence at the other end and try again to make the RJ45 crystal head at this end. How troublesome this is. In addition, it is very likely that crosstalk is caused by incorrect bypass .) 123 45678 The line sequence of t568a is: white green, green, white orange, blue, white blue, orange, white brown, brown The li

straight-through cable means that both ends of the crystal head adopt the T568A or T568B connection method at the same time, while the crossover cable adopts the T586A standard at one end of the crystal head and the T568B standard at the other end, that is, 1 and 2 of A crystal head correspond to 3 and 6 of B crystal head, while 3 and 6 of A crystal head corresp

connection port control switch on the MDI (uplink) and connect it with a direct connection line. If the Hub does not have a dedicated-level connection port, or you cannot use a level-level connection port, you must use a MDI-X port level connection, then we can use a line to achieve the purpose, the line reference is as follows.
