As network speeds continue to increase, so do the demands on the underlying cabling infrastructure. While early Ethernet standards were relatively tolerant of external interference, modern high-speed networks are significantly more sensitive to signal disturbances. In environments with numerous electrical devices, power cables, and densely packed network installations, selecting the right network cable has become an important factor in ensuring reliable performance.
When Interference Affects Signal Quality
Electromagnetic interference (EMI) is a common reality in many installations. Typical sources include LED lighting systems, industrial machinery, power cables and adjacent network cables.
As transmission frequencies increase, network cables become more susceptible to these interference sources. Proper cable shielding therefore plays an increasingly important role in maintaining stable data transmission.
Two types of interference are particularly relevant:
Both effects can negatively impact signal quality and become increasingly significant as data rates continue to rise.
Choosing the Right Shielding for the Application
Different environments require different shielding concepts.
For applications where maximum protection against interference is essential, S/FTP cables are often the preferred choice. In this design, each individual pair is shielded and the overall cable is protected by an additional braided shield. This provides excellent resistance against external interference and Alien Crosstalk.
In many patching and rack applications, U/FTP cables offer an ideal balance between shielding effectiveness, flexibility, and ease of installation. Here, each twisted pair is individually shielded while the overall cable remains lightweight and easy to handle.
Practical Examples
Diese unterschiedlichen Anforderungen spiegeln sich auch in unserem Produktportfolio wider. Das PKW-PIMF-KAT6A wurde für Anwendungen entwickelt, bei denen maximale Performance und eine hohe Störsicherheit gefragt sind. Die S/FTP-Schirmung bietet einen besonders hohen Schutz gegen äußere Einflüsse und Alien Crosstalk.
Das PKW-LIGHT-STP-K6A setzt hingegen auf eine U/FTP-Konstruktion. Dadurch bleibt das Kabel flexibel und eignet sich besonders für Bereiche mit hoher Portdichte oder beengten Platzverhältnissen.
