## Long description

The EFB Elektronik K5528BL.7.5 is a high-performance networking cable designed for demanding wired network environments. With a length of 7.5 m, Cat8.1 specification and S/FTP shielding, this cable supports data transfer rates up to 40000 Mbit/s and is terminated with RJ-45 connectors on both ends. Its durable jacket and blue color make it suitable for visible routing as well as structured cabling in server rooms, workstations, and home offices.
Advantages
Cat8.1 classification and S/FTP shielding reduce crosstalk and external electromagnetic interference, maintaining signal integrity at high frequencies. The RJ-45 terminations provide compatibility with common network equipment without the need for specialized interfaces. The 7.5 m length balances reach and manageability for typical rack-to-desk or patch-panel connections, while the blue outer sheath offers easy visual identification within cable bundles.
Suitable for
High-speed LAN links between switches, routers and servers
Patch panel to network device connections in data cabinets
Workstation or home office wired internet connections
Short-distance 40GBase-T links where Cat8.1 performance is required
Key specifications
Cable length: 7.5 m
Cabling standard: Cat8.1
Shielding: S/FTP (overall foil with individually shielded pairs)
Connectors: RJ-45 on both ends
Rated data transfer: up to 40000 Mbit/s
Application: 40GBase-T compatible
Color: Blue
How to use
Connect one RJ-45 plug to the network device (switch, router or NIC) and the other plug to the corresponding port on the second device or patch panel. Ensure connectors are fully inserted until the latch clicks to guarantee a secure connection. Route the cable to avoid sharp bends, excessive tension and proximity to strong electromagnetic sources. For best performance, maintain proper bend radius and avoid kinking the cable.
Usage recommendations
For optimal throughput, use this Cat8.1 S/FTP cable for short to medium distances in wired LAN segments and patching between high-speed equipment. Verify that connected hardware supports the intended link speed and follow structured cabling practices: label both ends, secure with cable management, and keep power and data cables separated to minimize interference.
