Networking cable EFB Elektronik K5528RT.1 RJ-45 Cat8.1 1 m Red

The EFB Elektronik K5528RT.1 is a Cat8.1 networking patch cable with RJ-45 connectors and a 1 m length. It supports 25GBASE-T and 40GBASE-T applications, offers up to 40,000 Mbit/s data transfer and is specified for operation up to 2000 MHz with a current maximum recommended transmission distance of 30 m. The cable uses S/FTP shielding to reduce electromagnetic interference and is supplied in red.

Advantages

Cat8.1 compliance and S/FTP shielding deliver improved signal integrity for high-speed links. The RJ-45 connectors provide backward compatibility with existing Ethernet equipment. Short 1 m length is convenient for rack or desktop connections where minimal slack and reduced crosstalk are required.

Suitable for

• 25GBASE-T and 40GBASE-T uplinks and connections
• High-speed server-to-switch or switch-to-switch patching in data centres
• Short-range connections in network racks and workstations (up to 30 m)

How to use

Connect one RJ-45 plug to the network device (switch, router or server) and the other plug to the corresponding port on the remote device. Ensure ports are rated for 25GBASE-T or 40GBASE-T where required. Route the cable avoiding tight bends and sources of strong electromagnetic interference to preserve signal quality. For best performance, keep the run within the specified maximum distance.

Recommendations

Use this Cat8.1 patch cable for short, high-speed connections in data centre and professional network environments; verify device port capabilities (25G/40G) and maintain cable runs within the recommended 30 m maximum.
