Networking Cable EFB Elektronik EC020200249 RJ-45 Cat8.1 3 m Yellow

The EFB Elektronik EC020200249 RJ-45 Cat8.1 3 m Yellow networking cable is a shielded high-speed Ethernet cable designed for demanding wired network connections. With Cat8.1 specification and S/FTP shielding, the cable supports very high data transfer rates up to 40000 Mbit/s while reducing electromagnetic interference. Gold-plated contacts on the RJ-45 plugs improve contact reliability and corrosion resistance, and the 3 m length provides flexibility for connections between network devices in racks, offices, or home setups. The bright yellow jacket makes the cable easy to identify in complex cabling environments.

Advantages

Cat8.1 performance enables extremely high bandwidth suitable for modern data center and professional networking needs. The S/FTP shielding (individual foil around each pair plus an overall braid) minimizes crosstalk and external interference for stable signal transmission. Gold-plated RJ-45 contacts ensure consistent electrical contact and reduced oxidation over time. The 3 m length balances reach and signal integrity, and the yellow outer jacket provides visual identification for organized cable runs.

Suitable for

• High-speed connections between switches, routers and servers
• Patch panels and network racks in data centers or server rooms
• Professional workstations requiring low-latency wired links
• Home lab setups and structured cabling where color coding is needed

Key specifications

• Category: Cat8.1
• Connector type: RJ-45 to RJ-45
• Shielding: S/FTP (individual pair foil + overall braid)
• Maximum data rate: up to 40000 Mbit/s
• Length: 3 m

How to use

Insert each RJ-45 connector into the corresponding Ethernet port on your network devices until the latch clicks into place. Use the cable to connect switches, routers, servers, patch panels or workstations as required. Ensure ports are compatible with Cat8.1 or support the intended link speed; for best performance, avoid sharp bends and excessive tension on the cable and keep it away from strong electromagnetic sources where possible.

Usage recommendations

For optimal performance, maintain proper cable management to prevent kinks, observe bend radius limits, and use compatible high-performance network ports and hardware. When deploying in structured cabling systems, label both ends and consider color coding to simplify identification and maintenance.
