ACT Yellow 0.25 meter LSZH U/UTP CAT6 datacenter slimline patch cable snagless with RJ45 connectors

The ACT Yellow 0.25m LSZH U/UTP CAT6 patch cable is a slimline datacenter cable designed for short interconnections. With a reduced diameter compared to standard CAT6 patch cords, it supports improved airflow in network cabinets and features snagless RJ45 connectors with gold-plated contacts. The U/UTP construction (unshielded twisted pair with overall jacket) and LSZH jacket provide reliable signal transmission and low-smoke, zero-halogen safety for indoor use.

Advantages

The slim 3.8 mm diameter lowers cable bulk and the smaller bending radius compared with regular CAT6 patch cords, which helps create better airflow inside racks. The LSZH jacket reduces smoke and halogen emissions in case of fire, and gold-plated RJ45 contacts improve contact reliability. Suitable for short links in datacenter and network patching where space and airflow management are important.

Suitable for

• Short patch connections in server cabinets and network racks
• Datacenter environments where improved airflow is required
• Indoor installations requiring LSZH materials
• Connections between switches, patch panels and servers over short distances

Key specifications

• Category: CAT6 U/UTP
• Length: 0.25 m
• Conductor gauge note: slimline cables use smaller conductors (28 AWG possible) which increases attenuation at higher frequencies
• Diameter: approx. 3.8 mm (slimline)
• Connectors: RJ-45 to RJ-45, snagless, gold-plated contacts
• Jacket: LSZH (low smoke zero halogen)
• Colour: Yellow

How to use

Install the patch cable between compatible RJ45 ports on switches, patch panels or servers for short link connections. Ensure connectors are fully inserted until the latch clicks and avoid sharp bends near the connector. Because slimline cables may use thinner conductors, keep link lengths short to limit signal attenuation and test connectivity after installation.

Recommendations

ACT recommends using shorter permanent link lengths than with standard 24 AWG patch cords to accommodate higher attenuation of slimmer conductors. For PoE applications, limit bundled slimline cables to around 24 cables to help control temperature rise in the bundle; current guidance (ANSI TSB-184-A) aims to limit temperature increase to under 15 °C above ambient for the centre cable.
