Cabo de rede EFB Elektronik K5528GR.1 RJ-45 Cat8.1 1 m cinzento

The EFB Elektronik K5528GR.1 is a 1 m Cat8.1 networking cable with RJ-45 connectors on both ends. It supports Cat8.1 performance with S/FTP shielding, a frequency range up to 2000 MHz and is designed for high-speed 25GBASE-T and 40GBASE-T applications with a maximum recommended transmission distance of 30 m.

Advantages

The cable provides Cat8.1-rated performance and S/FTP shielding to reduce crosstalk and external interference. With RJ-45 connectors and support for up to 40,000 Mbit/s throughput it is compatible with standard Ethernet ports while offering high-frequency capability up to 2000 MHz. Its 1 m length and grey colour make it suitable for short connections in racks and workstation environments.

Suitable for

• Short-distance high-speed links in data centers and server rooms (up to 30 m)
• 25GBASE-T and 40GBASE-T network connections using RJ-45
• Connecting switches, routers and high-performance NICs with RJ-45 ports

How to use

Connect each RJ-45 connector to the corresponding RJ-45 port on network devices such as switches, routers or network interface cards. Ensure that connected devices support the targeted 25GBASE-T or 40GBASE-T speeds for full performance. Avoid bending the cable sharply near the connectors and secure cable runs to prevent strain on the plugs.

Recommendations

For reliable 25G/40G performance keep cable runs within the recommended maximum distance of 30 m and install in environments free from excessive electromagnetic interference. Use compatible S/FTP infrastructure and follow standard cabling best practices for grounding and connector handling.
