Networking cable EFB Elektronik EC020200248 RJ-45 Cat8.1 2 m Yellow

The EFB Elektronik EC020200248 RJ-45 Cat8.1 networking cable is a 2 m yellow S/FTP cable designed for high-bandwidth data transmission. It supports very high transfer speeds and uses gold-plated RJ-45 connectors to maintain stable electrical contact. The cable’s construction and shielding help minimise electromagnetic interference and preserve signal integrity in congested network environments.

Advantages

This Cat8.1 cable provides up to 40000 Mbit/s data transfer capability while maintaining low attenuation across short distances. S/FTP shielding around each pair and an overall foil protects against crosstalk and external noise. Gold-plated RJ-45 connectors improve corrosion resistance and contact reliability, and the 2 m length offers flexibility for rack, desktop, and home network layouts. The yellow jacket makes the cable easy to identify in multi-cable installations.

Suitable for

• High-speed server connections in data centres and server rooms
• Short-distance backbone links and switch-to-switch connections
• Workstation connections requiring low-latency, high-throughput links
• Home or office networks where clear cable identification is needed

Key specifications

• Cable category: Cat8.1
• Length: 2 m
• Shielding: S/FTP (shielded foiled twisted pair with overall shield)
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Approximate maximum data rate: 40000 Mbit/s (dependent on network equipment and conditions)
• Cable colour: Yellow

How to use

Connect the RJ-45 plugs to the corresponding Ethernet ports on your devices, ensuring a secure click to confirm proper seating. Use the 2 m length to link switches, routers, servers, or workstations at short to medium distances. Route the cable to avoid sharp bends, excessive tension, and close proximity to high-power electrical lines to preserve shielding effectiveness. Verify link status indicators on network equipment after installation to confirm a negotiated connection speed.

Recommendations

For optimal performance, use this Cat8.1 cable in conjunction with compatible high-speed networking hardware (switches, NICs, and routers) that support multi-gigabit or higher link rates. Avoid running the cable alongside strong electromagnetic sources, and maintain bend radii recommended by the equipment manufacturer. For permanent installations, secure the cable with cable management accessories to prevent strain on connectors.
