Its vibrant yellow color adds a touch of style to your setup.

## Long description

The EFB Elektronik K5528GE.3 is a 3 m Cat.8.1 RJ-45 patch cable designed for high-speed Ethernet links. It supports 25GBASE-T and 40GBASE-T over RJ45 with a frequency range up to 2000 MHz and is intended for short-distance, high-bandwidth connections. The cable features S/FTP shielding and RJ-45 connectors on both ends, and comes in a yellow jacket for easy identification.
Advantages
The Cat.8.1 construction and S/FTP shielding reduce crosstalk and external interference, enabling data rates up to 40000 Mbit/s where supported. With a 3 m length and robust RJ-45 connectors, the cable is suited for reliable patching in racks and between switches or high-performance network devices. The yellow outer sheath makes cable management and identification easier in dense installations.
Suitable for
Short-run connections between switches, servers and high-speed network interfaces
25GBASE-T and 40GBASE-T applications using RJ-45 ports
Data centers, server rooms, and networking racks requiring high bandwidth
When it may not be suitable
This Cat.8.1 cable is optimized for short distances; its specified maximum transmission distance is currently 30 m, so it is not intended for long-haul cabling between buildings or across large campus environments. It also requires network equipment that supports 25GBASE-T or 40GBASE-T to achieve the highest data rates.
Key specifications
Category: Cat.8.1
Length: 3 m
Connectors: RJ-45 to RJ-45
Supported standards: 25GBASE-T, 40GBASE-T
Frequency range: up to 2000 MHz
Shielding: S/FTP
Colour: Yellow
How to use
Connect one RJ-45 end to the network device (switch, NIC or router) and the other end to the corresponding port on the opposite device. Ensure both devices support the intended speed (25G/40G) and that ports are configured for the correct link settings. Route the cable to avoid sharp bends and areas with strong electromagnetic interference to maintain signal integrity.
What to consider before purchase
Confirm that your network equipment supports 25GBASE-T or 40GBASE-T over RJ-45 to utilize full bandwidth.
Verify that a 3 m length is appropriate for your rack or deployment layout; the cable is intended for short-distance links (maximum currently 30 m).
Consider environmental requirements (e.g., flame rating or jacket material) for your installation location.
Usage recommendations
For best performance, use this Cat.8.1 S/FTP cable for direct patching within racks or between adjacent racks, keep cable runs under the specified maximum distance, avoid tight bends, and maintain proper grounding of shielded connectors and equipment.
