Patch cords (patch cords) takencall electrical or fiber optic cables that allow you to connect or connect electrical devices. The most common data products received in the design and creation of local area networks. To connect switches, connect workstations to network equipment, the patch cord 5e made in an industrial or artisanal way is often used here. Fiber patch cords are also in use.
To connect the disparate network components,need to use special cables. So, to connect a PC to a DSL router or switch, you will need to prepare a network patch cord. What it is? This is a segment of shielded or unshielded UTP cable from 1.5 m in length, on both sides of which RJ-45 connectors are fixed with a crimping tool.
There are standards for connecting such cables toother devices: TIA-568A and TIA-568B. How is patch 5e used to connect network devices? Standards determine the sequence of individual veins in colors within the connector. The fact is that inside the standard UTP cable under the insulating layer are twisted conductors. Here is the signal transmitted by them. An insulation layer covering such a conductor can have one of eight standard colors:
In the TIA-568A standard, the order of reference begins withwhite-green and green wires. In the TIA-568B variant, orange wires first go. Other differences in the sequence of the lived can be seen in the picture. Some network engineers when connecting connectors arbitrarily change the order of the conductors. This is not recommended. It is better to follow one of the standard schemes, so as not to get confused in the future.
Cable crimped on both sides is indispensable forsystem administrator. There are many devices that can be connected to the network using a patch cord. What are these devices? Their list is quite wide. Here are just the most popular options:
If you use lc lc patch cord, then they are usuallydevices of switching and routing communicate among themselves. This type of cables is also used to connect switches and other network equipment to patch panels.
Despite the simplicity of the device, patch cableshave certain differences. So, they can be categorized as 5, 5e or 6. The figure explains which materials are used for this cable, which type of RJ-45 connectors uses a specific UTP patch cord. What does this mean in practice? Different UTP cables support different data rates. Some of them are capable of providing greater signal transmission distance.
There is a common misconception.buyers, which is that they must have a CAT 6 cable in order to receive a Gigabit signal in their network. This statement is true only if cheap wires of dubious origin are purchased. A good quality cable category 5e, manufactured to the proper standards, will have a gigabit signal. Its only disadvantage is that it has not been developed or certified for this. Therefore, the manufacturer does not guarantee that the cable category 5 will support Gigabit Ethernet.
UTP 5th cables are commonly used in bulk.categories. They are cheap, simple and reliable. If these products are made with high quality, they will even hold a gigabit signal without any problems. But sometimes you can meet and patch cord 6 categories (about 3-5% of cases). What are the main differences of patch cord 5e? What is this magical wire used everywhere?
What are the secrets of the usual patch cord?What are the characteristics that make the product such a universal tool for building computer networks? The outer insulation layer protects single-wire copper strands twisted in pairs and having a diameter of 0.52 mm. Each conductor is covered with solid polyethylene. It protects the conductors from various interference and the ingress of water, oxidation. The UTP cable is highly flexible, which allows you to use the most unexpected routes for laying the network.
Network cable type "crossover" is aA special type of mounting cords, which are used for the device SKS. Their peculiarity is the cross-connection diagram of the connection of individual cores at the end directly with the connector. So, if on the one hand the TIA-568A model is used, on the other hand, the TIA-568B scheme is used.
