Networking cable EFB K5525FSW.25 Cat6a S/FTP (S-STP) 25 m RJ-45 to RJ-45 Black

EFB K5525FSW.25 is a 25 m Cat6a network cable with S/FTP (S‑STP) shielding and RJ‑45 to RJ‑45 connectors. The cable is designed for 10 Gbps Ethernet and supports up to 10000 Mbit/s data transfer rates. Gold‑plated contacts on the connectors offer stable electrical connection and corrosion resistance, while the S/FTP shielding minimises crosstalk and protects against electromagnetic interference in professional network environments.

Advantages

The S/FTP (S‑STP) shielding construction provides individual foil shielding for twisted pairs plus an overall braided shield, reducing near‑end crosstalk and improving immunity to external EMI sources. Cat6a performance ensures consistent throughput for demanding applications up to 10 Gbps over the specified length. Durable RJ‑45 connectors with gold‑plated contacts contribute to reliable signal transmission and long‑term mechanical endurance. The cable’s black jacket offers a neutral appearance suitable for rack and floor installations.

Suitable for

• 10 Gigabit Ethernet links in data centres and server rooms
• High‑speed LAN connections for offices and professional workspaces
• Switch-to-switch or switch-to-server patching in structured cabling
• Environments with elevated electromagnetic interference where shielded cables are required

Key specifications

How to use

Connect one RJ‑45 end to the network device (switch, router, server or NIC) and the other end to the corresponding port on the remote device. Ensure that both devices support the desired link speed and that ports are configured appropriately for 10 Gbps operation if required. Route the cable to avoid sharp bends and excessive tension; maintain recommended bend radius for Cat6a cables and keep the cable separated from large power sources to preserve shielding effectiveness.

Recommendations

For optimal performance, use the cable within its specified 25 m length for 10 Gbps links and verify link negotiation on both endpoints. When installing in environments with significant electromagnetic interference, ensure proper grounding of connected equipment and avoid running the cable parallel to high‑voltage power lines. Periodically inspect connectors for damage and replace the cable if the jacket or connector integrity is compromised.
