Cables for computer networks

Cables for IT networks - the foundation of modern infrastructure

IT network cables are a key element of every modern network installation.   In our daily practice, we see how important it is to choose the right cabling. It affects the performance and reliability of the entire network. Many customers ask us about the differences between the different types of cables. So we decided to prepare a comprehensive guide to this product category.

Types of Network Cables and Their Applications

Onninen's offer includes a wide selection of cables for computer networks. It includes, among others:

• Category 5e, 6, 6A and 7 U/UTP cables
• F/UTP cables cat. 5e, 6, 6A and 7
• S/FTP Cat 6 and 7 Cables
• FTP Cat. 5e, 6 and 6A Cables
• Multimedia Cables
• External cables

Each type of cable has its unique properties and applications.   Category 5e cables are suitable for smaller home networks. Category 6 and 6A cables are standard in offices and businesses. Category 7 provides the highest performance in data centers. In our experience, choosing the right cable category is crucial. It affects the speed of data transmission and resistance to interference.

Key parameters when selecting network cables

When selecting cables for IT networks, you should pay attention to several important parameters:

• Flammability class
• Insulation type (PVC, LSOH, LSZH)
• Cable length
• Shielding
• Installation location (indoor/outdoor)

The flammability class is particularly important in public buildings.   LSOH (Low Smoke Zero Halogen) cables emit less smoke and toxic gases in the event of a fire. This is crucial for human safety. Outdoor cables have additional protection against moisture and UV radiation. Shielding protects against electromagnetic interference. This is important in industrial environments.

Recently, in a project for a large shopping center, we used F/UTP cat. 6A cables. They provided high throughput and resistance to interference.   In the case of office reorganization, we most often recommend U/UTP category 6 cables.   They offer good value for money. They work well for most office applications.

Renowned brands of network cables in the Onninen offer

In our assortment you will find products of leading manufacturers. These include Alantec, Securitynet, A-Lan, Top Marki and Bitner. Each of these brands has its strengths. Alantec is famous for its reliability. Securitynet specializes in solutions for monitoring systems. A-Lan offers a wide range of products at affordable prices.

Our experience shows that cable quality is crucial for network stability.   Cheap, unbranded cables often cause problems. These can include connection breaks or speed drops. That's why we always recommend choosing proven manufacturers. Investing in good quality cabling pays off in the form of trouble-free network operation.

We often come across the question about the differences between U/UTP and F/UTP cables. U/UTP cables are unshielded. They work well in most office applications. F/UTP have an additional shielding foil. They protect against electromagnetic interference. They are ideal for industrial or medical environments.

For outdoor installations, it is crucial to use cables with UV protection.   Ordinary indoor cables quickly degrade when exposed to sunlight. This can lead to network failure. Outdoor cables have a special UV-resistant coating. This ensures their long-term durability.

Many customers ask us about Category 7 cables. They are relatively new on the market. They offer the highest throughput, up to 10 Gb/s. They are suitable for data centers and advanced industrial installations. For most companies, however, Category 6 or 6A cables are sufficient.

When designing a network, it is important to take future needs into account.   We often recommend installing cables of a higher category than currently required. This allows for easy expansion of the network in the future. It avoids the need to replace cabling when upgrading equipment.

At Onninen, we offer not only cables, but also comprehensive advice. Our specialists will help you choose the right products for your specific application. We also provide technical support during the design and installation of your network. This means that our customers can be sure that their network infrastructure will operate reliably.
