Cabo de rede EFB Elektronik K5528BL.10 RJ-45 Cat8.1 10 m azul

The EFB Elektronik K5528BL.10 networking cable is a 10 m Cat8.1 patch cable designed for high-speed wired networks. The cable uses S/FTP shielding and RJ-45 connectors on both ends, supporting 40GBase-T cabling technology and a maximum data transfer rate of 40000 Mbit/s. Its blue jacket provides clear visual identification in patch panels, server rooms, and structured cabling installations.

Advantages

S/FTP shielding reduces electromagnetic interference and crosstalk, improving signal integrity in dense or electrically noisy environments. Cat8.1 specification and 40GBase-T compatibility enable multi-gigabit and short-reach 40 Gbps links where supported by network equipment. RJ-45 terminations maintain compatibility with common switches, routers, and NICs designed for shielded twisted-pair connections. The 10 m length offers flexibility to connect racks, switches, and workstations without additional patching.

Suitable for

• Data center top-of-rack and switch-to-switch short-reach connections
• High-performance workstations and servers requiring multi-gigabit links
• Structured cabling in server rooms and telecom closets
• Environments with electromagnetic interference where shielded cables are needed

Key specifications

• Cable category: Cat8.1
• Shielding: S/FTP (overall braid with individually shielded pairs)
• Connectors: RJ-45 on both ends
• Cabling technology: 40GBase-T
• Maximum data transfer rate: 40000 Mbit/s
• Length: 10 m
• Colour: Blue

How to use

Connect one RJ-45 connector to the network interface of a switch, router, or network card and the other connector to the corresponding port on the target device. Ensure that both ports and devices support shielded cabling and the required speeds; attach cable shields to grounded metal patch panels or connectors where applicable to maintain shielding effectiveness. Avoid tight bending, kinking, or compressing the cable, and route it away from high-power electrical lines to preserve signal performance.

Recommendations

For optimal performance at 40GBase-T speeds, use the cable for short-reach connections within racks or between adjacent racks and confirm that connected equipment supports Cat8.1 or 40GBase-T. Maintain proper grounding of shielded components and follow recommended bend radius and installation practices for shielded twisted pair cables.
