Cabo de rede EFB Elektronik K5528GE.2 RJ-45 Cat8.1 2 m amarelo

The EFB Elektronik K5528GE.2 is a 2 m Cat8.1 networking cable with S/FTP shielding and RJ-45 connectors on both ends. It supports 25GBASE-T and 40GBASE-T applications over RJ45, offers a frequency range up to 2000 MHz and is designed for short high-speed links with a recommended maximum transmission distance of 30 m.

Advantages

S/FTP shielding provides improved protection against electromagnetic interference and crosstalk. Cat8.1 specification and 2000 MHz bandwidth enable high data rates up to 40000 Mbit/s for demanding network applications. The 2 m length and flexible jacket simplify routing in racks and workstations, while the RJ-45 terminations ensure compatibility with standard Ethernet ports. The yellow color makes the cable easy to identify in patch panels and cable runs.

Suitable for

• Short-distance high-speed links in data centers and server rooms
• 25GBASE-T and 40GBASE-T connections over RJ45
• High-bandwidth workstations and network switches
• Patching between switches and top-of-rack equipment

How to use

Connect one RJ-45 connector to the network switch or NIC and the other to the target device or patch panel. Ensure connectors are fully inserted and locked. Route the cable without sharp bends and avoid placing it alongside high-power electrical lines to minimise interference. For installations in racks, secure the cable using appropriate cable management to prevent strain on the connectors.

Recommendations

For reliable 25G/40G performance keep the cable length within the specified maximum of 30 m and use compatible Cat8.1-compliant equipment and RJ-45 ports. Inspect connectors before deployment and avoid excessive bending radii to maintain signal integrity.
