Networking Cable M-Cab EC020200304 RJ-45 Cat8.1 3 m Black

The M-Cab EC020200304 RJ-45 Cat8.1 3 m Black is a high-performance networking cable designed for demanding wired Ethernet environments. Meeting the Cat8.1 specification, the cable supports extremely high data rates and is constructed with S/FTP shielding and gold-plated RJ-45 connectors to maintain signal integrity and reduce crosstalk. Its 3 meter length and black jacket make it suitable for desktop connections, rack installations, and home or office networks where a short, robust link is required.

Advantages

Built to the Cat8.1 standard, this cable enables very high transfer speeds and low latency for applications that require fast, stable connections. The S/FTP shielding provides comprehensive protection against electromagnetic interference and near-end crosstalk, while the gold-plated RJ-45 plugs ensure reliable contact and corrosion resistance. The 3 meter length balances reach and cable management, and the black outer sheath offers a discreet appearance in professional and residential setups.

Suitable for

• High-speed Ethernet links in data centers and server rooms
• Connecting routers, switches, and network interface cards for gigabit and multi-gigabit applications
• Short to medium desktop or rack-to-rack connections where minimized interference is required
• Home office or professional workstations needing stable wired connectivity

Key specifications

• Standard: Cat8.1
• Maximum data rate: up to 40000 Mbit/s
• Cable length: 3 m
• Shielding: S/FTP (shielded foil with individually shielded pairs)
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Colour: Black

How to use

Insert each RJ-45 connector into the corresponding Ethernet port on your networking devices until a click confirms a secure connection. Route the cable to avoid sharp bends and sources of strong electromagnetic interference where possible; maintain a gentle bend radius and avoid pinching the jacket. For rack installations, secure excess length with cable ties or Velcro straps to keep airflow and access unobstructed. Verify link speed and duplex settings on connected devices to ensure they operate at the expected performance level.

Usage recommendations

For optimal performance, use this Cat8.1 cable in environments that benefit from shielded cabling, such as dense equipment racks or areas with potential EMI. Ensure connected hardware supports the intended multi-gigabit speeds and keep cable runs within recommended lengths for the installed infrastructure.
