Networking cable ACT DA6903 Cat6a U/FTP (STP) RJ-45 to RJ-45 Black 3 m

ACT DA6903 is a 3 m Cat6a U/FTP (STP) slimline patch cable with 90° angled up RJ‑45 connectors on both ends. The cable features a slim outer diameter of 3.8 mm, full copper 32AWG conductors and 50 µ gold‑plated RJ‑45 contacts. Its LSZH (Low Smoke Zero Halogen) jacket reduces the risk of toxic gas release in case of fire or thermal damage. Designed for high‑speed Ethernet, it supports Cat6a performance for 10 Gigabit Ethernet while reducing crosstalk and external interference, making it suitable for data center and office patching where space and airflow are important.

Advantages

The slimline design with a 3.8 mm outer diameter and a smaller bend radius improves airflow in server racks and network cabinets and allows neater cable routing in confined spaces. U/FTP shielding and solid copper 32AWG conductors provide reliable signal integrity for 10 Gigabit Ethernet. LSZH jacket material lowers the hazard from smoke and corrosive gases in the event of fire.

Suitable for

When it may not be suitable

This slimline Cat6a cable may not be suitable where high mechanical stress, frequent cable flexing, or heavy pulling is expected, because its smaller diameter and thinner conductors are optimized for fixed routing rather than rugged mobility. For environments requiring armoured protection or outdoor exposure, a different cable type with specific environmental or mechanical ratings should be chosen.

Key specifications

How to use

Route the cable through the rack or cabinet avoiding sharp edges and tight pinch points; the 90° angled up connectors are intended for connections where vertical clearance behind devices is limited. Insert the RJ‑45 plugs into compatible Cat6a ports until they click. Ensure proper cable management to maintain the recommended bend radius and to preserve airflow in the rack. No special termination is required, as the cable is preterminated on both ends.

What to consider before purchase

Recommendations

For optimal performance, maintain good cable management, avoid excessive bending or tension, and use this slimline Cat6a U/FTP patch cable in fixed rack or cabinet installations for 10 Gigabit Ethernet links where space and airflow are priorities.
