Straight and Cross Cable LAN


Posted on Feb 6, 2014

To connect two computers or connecting two HUB / switch with UTP cable, can use a crossover cable. If you connect computers to the HUB / switch, use straight cables. Straight cable is a term for a cable that uses the same standards on both ends of its wires, could EIA / TIA 568A or EIA / TIA 568B on both ends of the cable. Simply put, the sequence of colors

on both ends of the same. In straight cables, pin 1 at one end of the cable connected to pin 1 on the other end, pin 2 connected to pin 2 at the other end, and so on. So, when the PC sends data on pin 1 and 2 via the cable straight into the switch, the switch receives data on pins 1 and 2. Well, because pins 1 and 2 on the switch will not be used to send data as well as pins 1 and 2 on the PC, then switch In the drawing, pins 1 and 2 at the end A is connected to pins 3 and 6 at the end of B, as well as pins 1 and 2 at the end B is connected to pins 3 and 6 at the end of A. Thus, pins 1 and 2 at each end of the cable used to transmit data, while pins 3 and 6 on each end of the cable used to receive data, because the pins 1 and 2 are connected as opposed to pins 3 and 6. To identify whether a crossover or straight cable is to only see one end of the cable. If the sequence of colors of the wires on pin 1 is White Green, then the cable is a crossover (although if the other end also has the same color sequence that is White Green as pin 1, then the cable is a Straight). But fortunately, most cables use a standard EIA / TIA 568B on both ends of the cord. To connect the two HUB / switch, or connect two computers directly needed a crossover cable. But if the HUB / switch or Network Interface Card (NIC) or other network equipment to provide Uplinkport or MDI / MDI-X you can use straight cables for connecting to a regular port on...
