Networking cable DeLOCK 80576 RJ-45 Cat8.1 15 m Black

The DeLOCK 80576 networking cable is a Cat8.1 S/FTP cable, 15 m long, designed for high-speed Ethernet connections. It supports 40GBASE-T applications with a maximum frequency of 2 GHz and a data transfer rate of up to 40 Gbps. Both ends are fitted with RJ-45 connectors and the cable is finished in black for unobtrusive installation in home or office environments.

Advantages

The S/FTP shielding minimises electromagnetic interference and crosstalk, helping to maintain signal integrity at high frequencies. Cat8.1 specification and RJ-45 connectors provide backwards compatibility with lower-category Ethernet equipment while enabling up to 40 Gbps throughput over suitable infrastructure. Its 15 m length allows flexible routing between network devices without additional patching.

Suitable for

• 40GBASE-T Ethernet links
• High-speed data centers and server connections
• Backbone and aggregation cabling in offices
• Connections between switches, routers and network appliances

Key specifications

• Standard: Cat8.1
• Shielding: S/FTP (overall foil with individually shielded twisted pairs)
• Maximum frequency: 2 GHz
• Maximum data rate: up to 40 Gbps (40000 Mbit/s)
• Length: 15 m
• Connectors: RJ-45 – RJ-45
• Colour: Black

How to use

Connect one RJ-45 end to your network device (switch, router, server) and the other RJ-45 end to the corresponding port on the remote device. Ensure connectors are fully inserted and locked in place. Use appropriate cable management to avoid sharp bends and to maintain the recommended bend radius for high-frequency cables. Verify link speed and duplex settings on connected devices to confirm 40GBASE-T operation where supported.

Recommendations

For reliable 40 Gbps performance, use the cable within a structured cabling environment that supports Cat8.1 and 40GBASE-T, avoid electrical interference sources, and maintain proper connector seating and bend radius. If connecting to lower-category equipment, expect automatic negotiation to a supported lower speed.
