Network patch cable XXX_Assmann (Digitus) 21.45.3159 — Cat6a U/UTP RJ-45 to RJ-45, 20 m, black

ROLINE Recycled Material networking patch cable (model 21.45.3159) is a 20 m Cat6a U/UTP cable with RJ-45 connectors fitted on both ends and gold‑plated contacts. Designed for short-run high-speed Ethernet and 10 Gigabit applications, this unshielded cable provides standard Cat6a performance in a black, recycled-material jacket suitable for office, data‑centre patching and direct device connections. The cable uses four pairs of stranded copper conductors and is wired 1:1 according to EIA/TIA 568 for straightforward plug-and-play installation.

Advantages

This Cat6a U/UTP patch cable combines the performance required for Gigabit and 10 Gigabit networks with a flexible, moulded design that resists kinking and supports narrow bending radii. Gold‑plated contacts ensure reliable signal transfer and corrosion resistance, while the pre-assembled RJ‑45 plugs simplify installation without the need for termination tools. The recycled-material jacket reduces environmental impact while maintaining the mechanical robustness expected from category 6A cables.

Suitable for

• Connecting network devices to patch panels or switches in offices and server rooms
• Short horizontal runs and equipment interconnects requiring Cat6a performance
• 10 Gigabit Ethernet links over short distances
• Patch cabling for workstations, routers, modems and network appliances

Key specifications

• Cable category: Cat6a U/UTP (unshielded twisted pair)
• Length: 20 m
• Connector type: RJ‑45 plug to RJ‑45 plug, straight
• Contact plating: gold‑plated contacts
• Conductor: 4‑pair stranded copper
• Wiring: 1:1, EIA/TIA 568 standard
• Jacket color: black; jacket made from recycled material
• Design: pre‑assembled, moulded kink protection, flexible for narrow bending

How to use

Plug one RJ‑45 connector into the network port of a switch, patch panel or device and the other end into the corresponding port on the remote device or patch panel. Ensure connectors are fully inserted and the latch clicks into place to secure the connection. Route the cable following proper bend radius practices and avoid sharp edges or excessive tension. The cable is ready for immediate use in standard Ethernet environments and requires no additional termination.

Usage recommendations

For optimal performance, keep cable runs within recommended length limits for 10 Gigabit Ethernet and avoid running parallel to power lines or large electrical equipment. Use cable management such as horizontal managers or Velcro straps to prevent tight bends and reduce mechanical stress. Inspect connectors periodically for debris and ensure gold contacts are not heavily contaminated; clean gently if necessary.
