Sieťový kábel EFB Elektronik K5528GN.7,5 RJ-45 Cat8.1 7,5 m zelený

The EFB Elektronik K5528GN.7,5 is a Cat8.1 networking cable designed for high-speed Ethernet connections in home and professional environments. With a 7.5 m length and RJ-45 connectors on both ends, the cable supports 40GBase-T applications and delivers data transfer rates up to 40000 Mbit/s. The S/FTP shielding reduces electromagnetic interference and crosstalk, while the green jacket provides clear visual identification in cabling runs.

Advantages

The cable’s Cat8.1 specification and 40GBase-T compatibility enable very high bandwidth for data-intensive tasks. S/FTP shielding offers improved protection against external noise and maintains signal integrity across the full 7.5 m length. Standard RJ-45 connectors ensure compatibility with a wide range of network devices and infrastructure. The durable outer jacket and visible green color make installation and cable management easier in mixed-cable environments.

Suitable for

• High-speed LAN backbones and server room patching
• Data centers and network aggregation points
• Workstations and networked storage with high throughput needs
• Home offices and multimedia setups requiring gigabit and multi-gigabit links

Key specifications

• Cabling standard: Cat8.1
• Data rate: up to 40000 Mbit/s (40 Gbit/s)
• Cabling technology: 40GBase-T
• Shielding: S/FTP (shielded foil around each pair and overall braid)
• Length: 7.5 m
• Connectors: RJ-45 to RJ-45
• Color: Green

How to use

Connect one RJ-45 end to the network port of your router, switch, server or network interface card and the other end to the corresponding device. Ensure connectors are fully inserted until they click to secure the connection. Route the cable to avoid tight bends and keep it away from sources of strong electromagnetic interference where possible. For permanent installations, verify port and device capabilities to confirm 40GBase-T support where required.

Recommendations

For optimal performance, use this Cat8.1 S/FTP cable in short to medium-length runs up to 7.5 m and pair it with compatible 40GBase-T or multi-gigabit equipment. Maintain proper bend radius, avoid pinching the cable, and label both ends for easier identification in dense patch panels.
