Netwerkkabel EFB Elektronik K5528GE.10 RJ-45 Cat8.1 10 m geel

The EFB Elektronik K5528GE.10 is a 10 m Cat8.1 RJ-45 patch cable designed for high-speed copper Ethernet links. It supports 25GBASE-T and 40GBASE-T transmission standards, offers a frequency range up to 2000 MHz and is intended for short-distance links up to 30 m. The cable uses S/FTP 4x2xAWG24/7 construction, has an LSZH jacket and comes in yellow with RJ-45 connectors on both ends.

Advantages

The Cat8.1 construction with S/FTP shielding reduces electromagnetic interference and crosstalk, enabling reliable operation at multi-gigabit rates. A compact 8 mm outer diameter and a flexible LSZH jacket make the cable manageable in racks and patch panels while meeting low-smoke, halogen-free safety requirements. RJ-45 termination ensures compatibility with standard 25G and 40G copper RJ45 ports.

Suitable for

• 25GBASE-T and 40GBASE-T short-reach connections (up to 30 m)
• Server-to-switch and switch-to-switch links in data centers
• High-density patch panels and rack installations
• Environments requiring LSZH cable jackets for safety

How to use

Connect each RJ-45 connector to the corresponding ports on network devices such as switches, servers or patch panels. Ensure that cable runs do not exceed the intended maximum distance for Cat8.1 copper links (recommended up to 30 m for 25G/40G operation). Route the cable avoiding tight bends and excessive pulling force; use appropriate cable management to maintain bend radius and prevent strain on the connectors.

Recommendations

For optimal performance at 25GBASE-T and 40GBASE-T speeds, keep cable length within 30 m, use quality RJ-45 ports rated for the corresponding speeds, and maintain good cable management to minimise interference and mechanical stress.
