ACT FB8103 Cat8 U/FTP (STP) networking cable 3 m, RJ-45 to RJ-45, black

ACT FB8103 is a Cat8 U/FTP (STP) slimline datacenter patch cable with RJ‑45 connectors on both ends and a length of 3 m. It supports a maximum bandwidth of 2000 MHz (40 Gbit) and is designed for short-run interconnects in server racks and network cabinets. The cable uses full copper 30 AWG conductors, 50 µin gold‑plated RJ‑45 contacts and an LSZH (Low Smoke Zero Halogen) jacket. All units comply with international standards and are 100% tested.

Advantages

The slimline construction reduces outer diameter to approximately 5 mm, improving airflow inside cabinets and allowing denser cable routing compared with standard thicker Cat8 patch cords. LSZH insulation lowers the risk of toxic gas release in case of fire. Full copper conductors and gold‑plated contacts provide reliable electrical connection and corrosion resistance. The cable is snagless for easier handling in tight spaces.

Suitable for

• Short-distance links between switches and servers or NAS devices in datacenters
• High-speed backbone or aggregation connections within racks or cabinets
• Environments where improved airflow and compact cabling are required

When it may not be suitable

The cable uses 30 AWG conductors; although functional for short runs, thinner gauge conductors have higher attenuation than the 22–28 AWG range referenced in ISO/IEC and TIA standards, so performance over very long distances may be reduced. For long horizontal runs or where the lowest possible attenuation is required, thicker-gauge Cat8 or fiber solutions may be more appropriate.

Key specifications

• Category: Cat8 U/FTP (STP)
• Length: 3 m
• Bandwidth: up to 2000 MHz (40 Gbit)
• Conductor: full copper, 30 AWG
• Connector type: RJ‑45 to RJ‑45, straight male
• Contact plating: 50 µin gold
• Jacket: LSZH (Low Smoke Zero Halogen)
• Outer diameter: ~5 mm (slimline)
• Colour: Black

How to use

Connect one RJ‑45 end to the switch or other active device and the opposite RJ‑45 end to the target device such as a server or NAS. Route the slimline cable through cable management paths in the rack or cabinet, taking advantage of the reduced bending radius to maintain tidy cable runs and improved airflow. Ensure connectors are fully inserted until the latch clicks and avoid sharp bends at the connector boot to prevent stress on the termination.

What to consider before purchase

• Required link length and whether a 3 m patch cable covers the distance between devices
• Suitability of 30 AWG conductors for your application, especially regarding attenuation at higher frequencies over longer runs
• Need for LSZH jacket for safety requirements in your facility
• Compatibility of RJ‑45 connectivity with your equipment ports

Usage recommendations

Use this slimline Cat8 U/FTP patch cable for short, high‑speed connections inside racks where space and airflow are priorities; for runs beyond typical server-to-switch distances, evaluate attenuation requirements and consider alternatives if necessary.
