Networking cable ACT Cat6a U/UTP (UTP) DD7903 — RJ‑45 to RJ‑45, 3 m, Black

ACT DD7903 is a slimline Cat6a U/UTP patch cable with RJ‑45 connectors on both ends and gold‑plated contacts. The cable has a 3 m length and a narrow outer diameter, designed to support high-speed 10GbE networks while saving space in server racks and network cabinets. The jacket is LSZH to reduce toxic smoke in case of fire or short circuit.

Advantages

The slim 3.6 mm outer diameter and reduced bend radius allow denser cable routing and improved airflow in cabinets compared with standard Cat6a patch cords. The cable uses full copper 28 AWG conductors and 50 µin gold‑plated RJ‑45 contacts for reliable signal transmission. A 90° angled down to 90° angled up connector configuration enables neat connections where vertical space is limited.

Suitable for

• Connecting switches, routers and patch panels in data centers and network cabinets
• High-density rack installations where airflow and space are critical
• Office and home LAN setups requiring 10GbE performance

When it may not be suitable

This slimline cable is not intended for situations requiring additional mechanical protection or ruggedized outdoor cabling; its smaller diameter provides less physical robustness compared with thicker, armored cables. If the installation needs a straight connector orientation rather than angled connectors, choose a version with straight or left/right angled RJ‑45 plugs.

Key specifications

• Category: Cat6a U/UTP (unshielded)
• Length: 3 m
• Outer diameter: 3.6 mm
• Conductor: full copper, 28 AWG
• Contacts: 50 µin gold-plated RJ‑45
• Connector configuration: RJ‑45 90° angled down to RJ‑45 90° angled up
• Jacket material: Low Smoke Zero Halogen (LSZH)
• Supports: 10 Gigabit Ethernet, PoE up to 30 W
• Colour: Black

How to use

Route the cable through the rack or cabinet keeping bends gentle within the cable's bend radius. Plug the angled RJ‑45 ends into the appropriate ports on switches, patch panels or network devices, ensuring secure seating of the connectors. For optimal airflow and cable management, group slimline cables together and avoid tight kinks.

What to consider before purchase

• Required connector orientation (angled down/up, straight or left/right angled)
• Whether a slimline 3.6 mm diameter provides sufficient mechanical protection for your environment
• Compatibility with required network speed (10GbE) and PoE power needs
• Whether LSZH jacket is required for your building or data centre fire-safety policies

Usage recommendations

Use the ACT Cat6a U/UTP slimline cable for high-density rack wiring to improve airflow; select the connector orientation that matches port placement and avoid sharp bends to maintain signal integrity.
