Networking cable EFB Elektronik EC020200261 RJ-45 Cat8.1 5 m Grey

The EFB Elektronik EC020200261 RJ-45 Cat8.1 5 m Grey networking cable is a shielded Ethernet cable designed for high-speed data transmission in wired networks. Compliant with the Cat8.1 specification, the cable supports multi-gigabit and 40 Gbit/s class links for short-distance connections and comes terminated with gold-plated RJ-45 connectors. The grey jacket houses individually paired conductors with S/FTP shielding to reduce crosstalk and external electromagnetic interference, delivering stable signal quality for demanding network setups.

Advantages

The cable’s Cat8.1 performance enables data transfer rates up to 40000 Mbit/s for compatible equipment and supports advanced networking standards requiring high bandwidth. S/FTP shielding provides improved protection against electromagnetic interference and near-end crosstalk compared with unshielded alternatives. Gold-plated RJ-45 connectors enhance contact reliability and corrosion resistance, while the 5 m length balances reach and signal integrity for typical office, server room, or AV rack installations.

Suitable for

• Short-run 25/40 Gbit/s links in data centres and server rooms
• High-bandwidth workstation and NAS connections
• Professional AV setups and video streaming over Ethernet
• Secure wired connections in environments with electromagnetic interference

Key specifications

• Category: Cat8.1
• Length: 5 m
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Shielding: S/FTP (overall foil + individually foil-wrapped pairs)
• Colour: Grey
• Suitable for multi-gigabit and 40 Gbit/s class connections (short reach)

How to use

Connect each RJ-45 plug to the corresponding Ethernet port on your network devices, ensuring a secure seating of the latch to prevent accidental disconnection. Use this cable for direct device-to-switch, switch-to-switch (within supported short distances) or device-to-patch-panel connections. Avoid tight bends near the connector ends and do not route the cable alongside high-voltage power lines to maintain optimal signal integrity. For best performance, verify that connected equipment supports the intended link speed and that patch panels and switches are compatible with Cat8.1 performance.

Usage recommendations

For installations that require sustained 25/40 Gbit/s throughput, keep cable runs within recommended short-reach distances and use compatible shielded network hardware and grounding practices. Regularly inspect connectors for damage and replace cables that show visible wear to preserve reliable, high-speed operation.
