Networking Cable EFB Elektronik K5528GN.5 RJ-45 Cat8.1 5 m Green

The EFB Elektronik K5528GN.5 is a Cat8.1 RJ-45 patch cable with a length of 5 m, designed for high-speed Ethernet links. It supports 25GBASE-T and 40GBASE-T applications, offers a frequency range up to 2000 MHz and a maximum recommended transmission distance of 30 m. The cable uses S/FTP shielding and delivers data rates up to 40000 Mbit/s, suitable for demanding network environments.

Advantages

The Cat8.1 construction combined with S/FTP shielding reduces crosstalk and external interference, enabling stable high-frequency transmission. RJ-45 connectors provide broad compatibility with existing network equipment. The 5 m length and flexible jacket make the cable easy to route in racks and server rooms, while the green color helps with visual cable management.

Suitable for

• 25GBASE-T and 40GBASE-T short-range links
• High-speed server and switch interconnects
• Data centre patching within the 30 m distance limit
• Environments requiring shielded cabling to minimise EMI

How to use

Connect one RJ-45 connector to the network port of a compatible switch, server or network interface and the other connector to the corresponding port on the connected device. Ensure both endpoints support 25GBASE-T or 40GBASE-T where these speeds are required. Route the cable to avoid sharp bends and excessive tension; maintain the recommended maximum length for optimal performance.

Recommendations

For best results in high-speed installations, use the cable for in-rack or short patching runs up to 30 m, verify equipment compatibility with 25G/40GBASE-T, and avoid running parallel to unshielded power lines to reduce electromagnetic interference.
