Networking cable ACT DA7903 Cat6a U/FTP (STP) Black, 3 m, RJ-45 to RJ-45, gold-plated contacts

ACT DA7903 is a 3 m Cat6a U/FTP (STP) slimline patch cable with RJ-45 connectors on both ends. The cable has a reduced outer diameter to improve airflow in racks and cabinets while supporting high-speed Ethernet and 10 Gigabit networks. Gold-plated RJ45 contacts and full copper 32AWG conductors provide reliable signal transfer and corrosion resistance. The jacket is Low Smoke Zero Halogen (LSZH) to lower the risk of toxic gases in case of fire.

Advantages

The slimline 3.8 mm diameter design saves space and allows a smaller bend radius compared with standard CAT6A cables, helping to maintain neat cable runs and better airflow in server racks and network cabinets. Shielding (U/FTP) and gold-plated contacts improve signal integrity and long-term connection reliability. The LSZH jacket reduces hazardous smoke and halogen release in the event of cable damage by fire or short circuit.

Suitable for

When it may not be suitable

This cable is slimline and uses 32AWG conductors, which are thinner than standard thicker-gauge cables; it is designed for typical data center and office patching rather than long-distance runs or environments that require heavy-duty mechanical strength. For connections requiring higher PoE power than specified or extended outdoor burial use, choose a cable rated for those conditions.

Key specifications

How to use

Route the ACT DA7903 patch cable between RJ-45 ports, ensuring the angled connectors fit the available space behind equipment or within cabinet panels. Avoid sharp bends beyond the recommended bend radius and secure cables to maintain airflow and reduce strain on connectors. The angled down to angled up configuration is intended to minimize connector stress when ports are directly above or below each other.

What to consider before purchase

Recommendations

Use the ACT DA7903 in dense rack environments and tight spaces where preserving bend radius and improving airflow are priorities; pair with shielded patch panels and grounding practices for optimal performance.
