Networking Cable EFB Elektronik K5528GR.10 RJ-45 Cat8.1 10m Grey

The EFB Elektronik K5528GR.10 RJ-45 Cat8.1 10m Grey is a high-performance networking cable designed for demanding wired Ethernet environments. With a 10 m length and RJ-45 terminations, the cable supports 40GBase-T applications and data transfer rates up to 40000 Mbit/s. Its S/FTP (S-STP) shielding construction reduces electromagnetic interference and crosstalk, helping to maintain signal integrity in dense installations and near other electrical equipment. The grey jacket offers a neutral appearance suitable for professional and home network layouts.

Advantages

The cable's Cat8.1 specification provides increased bandwidth and lower latency compared with earlier twisted-pair standards, enabling reliable high-speed connections for servers, switches and workstations. S/FTP (S-STP) shielding around individual pairs and the overall bundle minimizes external noise and pair-to-pair interference. Plug-and-play RJ-45 connectors ensure compatibility with standard Ethernet ports without additional adapters. The 10 m length offers flexibility for rack-to-desk or equipment-to-switch connections while avoiding the need for intermediate patch panels in many setups.

Suitable for

• Server room uplinks and switch-to-switch connections requiring 40GBase-T performance
• High-bandwidth workstations, NAS devices and storage systems
• Audio/video streaming and real-time data transfer in production environments
• Structured cabling runs inside offices, data centers and telecom cabinets

• Maximum data transfer rate: up to 40000 Mbit/s
• Cabling technology: 40GBase-T
• Shielding: S/FTP (individually shielded pairs with overall shield)
• Colour: Grey

How to use

Connect one RJ-45 end of the cable to the Ethernet port of your switch, router or NIC and the other end to the destination device. Ensure both connected devices support the intended link speed and negotiate 40GBase-T where applicable. Route the cable away from sources of strong electromagnetic interference and secure it with appropriate ties or cable management to prevent strain on the connectors and excessive bending. For best performance, avoid tight bends and keep the cable within recommended bend radius guidelines.

Recommendations

Verify device compatibility for Cat8.1 and 40GBase-T operation before deployment. Use the cable for permanent or semi-permanent links within racks and between equipment where 10 m length is sufficient; for longer runs, choose appropriate in-wall or fiber solutions. Periodically inspect connectors for dust and damage and replace the cable if shielding or jacket integrity is compromised.
