Patch Cables
Patch cables or patchcords are short, prefabricated copper cables of the twisted-pair type, terminated on both ends with RJ45 (8P8C) connectors. Their purpose is to connect components within a computer network. To better understand the function and usage of patch cables, let’s explore their applications.
What Are Patch Cables Used For?
The wide range of applications for patch cables makes them an essential component when setting up a network. Patch cables are useful in nearly every LAN network. They are a mandatory element in any server room or access point. We use them to connect computers, active components such as routers, or passive ones like patch panels. There is nothing stopping you from using a patch cable to connect a computer to a network socket.
Patch Cable vs. Crossover Cable
Depending on the devices you want to connect, you will choose either a patch cable (patchcord) or a crossover cable. If you need a cable to connect a computer socket to a switch, a patch cable is the appropriate choice. These cables connect the same pins, making their setup relatively simple. Two devices of the same type require a crossover cable, where pins are connected according to a specific wiring scheme. Nowadays, network installation has become much easier for installers. Most devices automatically switch the port type to crossover upon detecting a patchcord connection. This avoids the need for additional changes to the installation.
Patch Cable — What to Consider?
Every LAN network requires solutions tailored to its needs, and this also applies to choosing the right patch cable. One key factor to consider is the cable’s bandwidth — the higher the cable category, the better its performance. The choice of a patchcord also depends on whether the LAN network is in an area exposed to electromagnetic interference. If so, shielded patchcords are necessary. These are marked with the letter **F** for foil shielding, **S** for mesh shielding, or **SF** for dual shielding with both elements. The length of the patch cable and its suitability for specific conditions are also critical, especially if it is used outdoors.
Patch Cables — Star Topology
With patch cables, we can connect devices in a computer network using star topology. In this setup, all endpoint devices converge at a single point, called the access point, where the network switch is located. This solution is typically used only when there is a limited number of computers, although it still results in a significant amount of cable usage.
securityNET Patchcords
The securityNET brand offers patchcords in categories 5e, 6, and 6A. Each of these options is available in both shielded and unshielded versions. You also don’t need to worry about finding a patch cable of the right length. SecurityNET cables are available in lengths starting from 0.25 meters and going up to 30 meters. This means you can find a patch cable even for the most demanding LAN networks. Their high quality and strict production control ensure that networks are extremely durable.
