What is a patch cable?
Patch cables are the backbone of modern networks. They connect devices such as computers, switches, routers and servers, enabling the exchange of data. Here are their main functions:
- Connecting network devices: Patch cables are used to connect network devices such as computers, switches, routers and servers. They enable communication and data exchange.
- Data transmission: Patch cables transmit data between network devices. The data is sent via the cables in the form of electrical signals.
- Network configuration: Patch cables make it possible to configure and adapt networks as required. By reconnecting patch cables, they enable flexible adaptation and optimization of network connections.
- Troubleshooting: By testing the connection with different patch cables, network problems can be identified and rectified.
The quality and specifications of a patch cable have a significant impact on the performance of the network. It is therefore important to select the right patch cable for your specific network requirements.
Spoiled for choice? How to find the perfect patch cable
The selection of the right patch cable depends on several factors::
- Category: The cable category, such as Cat 5e, Cat 6 or Cat 7, determines the maximum transmission speed and bandwidth. For Gigabit Ethernet and higher speeds, we recommend at least Cat 5e cables. At Bürklin Elektronik, therefore, we start our range with this quality standard.
- Length: Patch cables are available in various lengths from 0.5 to 30 meters. The length should be adapted to the area of application in order to avoid cable clutter.
- Intended use: Different patch cable types are used depending on the area of application. 1:1 cables (straight-through) connect devices with different functions, for example computers with a switch, while crossover cables are used for the direct connection of similar devices, i.e. computers with computers.
- Shielding: The shielding influences the performance and reliability of a patch cable. Unshielded cables (UTP) are less expensive and more flexible, but offer less protection against electromagnetic interference. Shielded cables (STP, FTP) offer better protection, but are more expensive and less flexible.
- Connector type: RJ45 connectors are common in Ethernet networks, while RJ11 connectors are typically used for telephone lines. It is important to choose the correct connector type for your specific application.
CAT 5, CAT 6, CAT 7 and more: Which category do I need?
After the fundamental considerations for choosing the right patch cable, it is now time to look at the specific categories. From CAT 5, which is sufficient for standard home applications, to CAT 8, which is intended for professional networks – each category is designed for specific network environments::
- CAT 5: The standard for network cables supports signal rates of up to 100 MHz and is suitable for gigabit operation. CAT 5 cables are sufficient for most home users.
- CAT 6: Frequently used in the professional sector, they achieve operating frequencies of up to 250 MHz. CAT 6a patch cables even support 500 MHz and are suitable for 10 Gigabit Ethernet.
- CAT 7: CAT 7 patch cables are heavily shielded and reach operating frequencies of up to 600 MHz. CAT 7a even manages up to 1,000 MHz.
- CAT 8: Mainly used in the professional sector, the high-quality CAT 8 cables achieve operating frequencies of up to 2,000 MHz.
The cable length influences the transmission speed – the longer the cable, the lower the speed.
Reliable data transfer with RJ45 connectors

The correct patch cable assignment of the RJ45 plugs is crucial. There are two standardized connector types: RJ45 and GG45.
RJ45 plugs are widely used in network technology and are used to connect ethernet cables to routers, switches and computers. They have eight pins and are usually compatible with Cat 5e or Cat 6 cables.
GG45 connections are specially developed for CAT 7 cables and enable the full bandwidth. The correct assignment is particularly important for PoE (Power over Ethernet)-capable networks, as the power is supplied via the data lines.
Choosing between 568A and 568B: Both are widely used standards for wiring in modern networks. The choice often depends on the existing wiring and regional preferences. In the USA, for example, 568B is more common, while 568A is often used in Europe. Consistency throughout the network is important. A mixture of 568A and 568B can lead to connection problems. For certain applications, such as the direct connection of two computers, a crossover cable may be required.
Color coding: Many patch cables are color coded to allow easy identification and management of the network. The EIA/TIA color code defines the assignment according to the 568A and 568B standards.
Copper vs. glass fiber patch cable: Which is suitable for my requirements?
Copper cables have proven themselves in many areas, but advancing technology and increasing demands on networks are bringing glass fiber cables more and more into focus. The following section takes a closer look at the areas of application for both materials.
Copper patch cables are an essential component of modern network infrastructures and, thanks to their specific properties, offer clear advantages that make them suitable for various applications. The paired twisting of the copper strands in these cables minimizes electromagnetic interference, so-called EMI. That allows stable and efficient data transmission.
The quality of the inner conductor plays a decisive role in signal integrity. This is because high-quality copper ensures optimum signal quality and supports longer transmission lengths. The flexibility of copper patch cables facilitates installation and maintenance. Widespread compatibility with existing network devices and infrastructures are further plus points, while their cost efficiency makes them an economical choice for many network applications.
Typically, copper patch cables are available in lengths of one to fifteen meters, making them ideal for flexible use in network environments, for example to connect patch panels or end devices to power outlets. These properties make copper patch cables a reliable choice for many network applications, from simple home networks to more complex corporate structures.
In addition to conventional copper cables, there are also glass fiber patch cables, which are characterized by their advanced technologies. The low signal losses lead to more efficient and reliable data transmission, which is a clear advantage of fiber optic cables. In terms of robustness, glass fiber cables offer high resistance to external influences such as magnetic fields, humidity and the cold.
Their range is considerable, as they can reach lengths of up to 450 meters in combination with network installation cables. This makes glass fiber cables an excellent choice for extensive networks.
In addition, the energy efficiency of glass fiber patch cables is high, as they consume less power. The use of glass fiber patch cables is therefore ideal in data centers, industrial facilities and other demanding environments where high bandwidth and speed are required.
Customization on demand – How to crimp patch cables?
Crimping is a central process in network technology. It enables the individual adjustment of the cable length and ensures secure and efficient data transmission. To crimp patch cables, the copper wires of the cable are pressed firmly into the RJ45 connector to create a stable electrical connection. Make sure that all components are of high quality to ensure optimum performance and longevity. You can find suitable items in our online store at any time.
