Patch Cable S-Conn Cat 8.1 F/FTP double-shielded, 2000 MHz, halogen-free, black, 3.0 m

S-Conn Cat 8.1 patch cable, F/FTP double-shielded and halogen-free, rated to 2000 MHz, is a high-frequency copper connection cable designed for demanding network environments. The cable is intended for short-run, high-speed Ethernet links and offers improved protection against crosstalk and electromagnetic interference. Supplied in black with a 3.0 m length, this patch cable supports modern multi-gigabit applications such as 25G and 40G Ethernet within data centres, server racks and structured LAN installations.

Advantages

The double-shielded F/FTP design combines an overall foil plus individually foiled pairs to reduce external EMI and pair-to-pair crosstalk, helping to maintain signal integrity at frequencies up to 2000 MHz. The halogen-free jacket reduces the risk of toxic gas emission in the event of fire and the 3.0 m length provides flexibility for rack-to-rack or patch panel connections. The cable is backwards-compatible with lower Ethernet categories while being optimised for higher-speed, short-distance links.

Suitable for

• 25G and 40G Ethernet short-reach links in data centres
• High-density server rack patching and switch-to-switch connections
• Structured LAN installations requiring low interference and high bandwidth
• Environments where halogen-free materials are required for safety standards

When it may not be suitable

This Cat 8.1 patch cable is designed primarily for short-reach, high-frequency applications; it is not intended for long-distance backbone runs where fibre optic cabling would be more appropriate. It may be over-specified for basic home networks or low-speed Ethernet needs where Cat5e or Cat6 cabling already meets performance requirements.

Key specifications

• Category: Cat 8.1
• Shielding: F/FTP (overall foil + individually foiled pairs)
• Frequency rating: up to 2000 MHz
• Conductor type: stranded copper (suitable for patch cords)
• Jacket material: halogen-free
• Colour: black
• Length: 3.0 m
• Intended use: short-reach, high-speed Ethernet links (e.g., 25G/40G)

How to use

Connect the S-Conn Cat 8.1 patch cable between compatible RJ45 ports on switches, patch panels or servers. Ensure that both ends are fully inserted until the latch engages and that connected equipment supports the required multi-gigabit speeds. Route the cable with gentle bends and avoid tight loops or sharp edges; maintain separation from strong EMI sources when possible to preserve signal quality. For installation in racks, use standard cable management accessories to prevent stress on the connectors.

What to consider before purchase

• Verify that network devices have compatible RJ45 ports and support the target multi-gigabit speeds (e.g., 25G/40G).
• Check required cable length and available rack space to ensure 3.0 m is appropriate.
• Confirm whether halogen-free jacket material is required by site safety regulations.
• Consider whether stranded conductor patch cable is suitable for your installation versus solid-core cabling used in permanent horizontal runs.

Usage recommendations

For best performance, use this Cat 8.1 F/FTP patch cable for short, high-speed connections inside racks and between adjacent equipment. Keep cable runs within recommended lengths for copper links, avoid tight bends and secure the cable to minimise movement and connector strain.
