Network Cable DeLOCK RJ45 Cable plug to plug Cat.8.1 0.25 m Black

The DeLOCK RJ45 Cat.8.1 network cable (0.25 m) is designed for high‑speed 40GBASE‑T Ethernet connections. It supports frequencies up to 2 GHz and data rates up to 40 Gbps, and uses U/FTP shielding to reduce electromagnetic interference. Both ends feature RJ‑45 plugs and the cable comes in a black sheath made from a flexible material that increases resistance to strain.

Advantages

This Cat.8.1 cable provides high bandwidth for 40GBASE‑T applications, low interference due to U/FTP shielding, and compact dimensions for short-link installations. The flexible jacket improves handling and routing in tight spaces while maintaining mechanical durability.

Suitable for

• Short‑reach 40GBASE‑T Ethernet links
• High‑speed server and switch connections
• Patching in data centres and telecom cabinets
• Desktop and office network connections requiring compact cabling
