bkl electronic RJ45 Patch Cable CAT 8.1 S/FTP, 1 m, Black, Halogen-free (Model 144035)

The bkl electronic RJ45 Patch Cable CAT 8.1 S/FTP, 1 m, Black, Halogen-free is a short, high-performance Ethernet patch cable intended for demanding network environments. It features CAT 8.1 specification and S/FTP shielding to support high-frequency data transmission and reduce electromagnetic interference on short links between switches, patch panels and servers. The halogen-free jacket reduces toxic gas emissions in case of fire and the compact 1 m length is suitable for tidy cable routing in racks and dense setups.

Advantages

This patch cable provides CAT 8.1 performance for up to multi-gigabit and 25/40 GBASE-T class connections over short distances while S/FTP shielding (overall foil plus individually shielded pairs) improves protection against crosstalk and external EMI. The halogen-free outer material meets safety requirements for installation in environments where reduced smoke and corrosive gas emissions are desired. Its 1 m length and standard RJ45 connectors make it convenient for patching in server rooms, telecom cabinets and network distribution frames.

Suitable for

• Short horizontal and patch links in data centers and server rooms
• Connections between switches, patch panels, routers and servers
• Environments requiring enhanced EMI protection and reduced fire‑toxicity
• High-speed Ethernet applications where CAT 8.1 performance is specified

When it may not be suitable

This 1 m cable is intended for short interconnects; it is not suitable for long-distance backbone runs or for installations requiring cable lengths greater than one meter. For environments where unshielded cabling is preferred or where CAT 8.1 performance is not required, lower-category or unshielded alternatives may be more cost-effective.

Key specifications

• Cable category: CAT 8.1
• Shielding: S/FTP (overall foil with individually shielded pairs)
• Connector type: RJ45 on both ends
• Length: 1 meter
• Color: Black
• Jacket material: Halogen-free
• Intended use: Short patch links, high-frequency Ethernet

How to use

Route the cable between the two RJ45 ports to be connected, ensuring connectors are fully inserted until the latch clicks. Keep the cable path clear of sharp bends and avoid tight loops to maintain performance; follow standard bend radius guidelines for twisted‑pair cables. In environments with high EMI, make sure shield terminations at both ends are properly connected to grounded shielded connectors or panels to ensure the S/FTP shielding functions correctly.

What to consider before purchase

• Required cable length and whether 1 m is sufficient for your patching needs
• Whether CAT 8.1 performance and S/FTP shielding are necessary for your network topology and devices
• Compatibility of connected equipment with RJ45 and shielded cabling
• Installation environment safety requirements that justify halogen-free jackets

Usage recommendations

Use this CAT 8.1 S/FTP patch cable for short, high-speed connections inside racks and patch panels. Ensure both ends are terminated to shielded RJ45 ports or properly grounded panels to benefit from the full shielding performance. Avoid exceeding recommended bend radii and keep the cable away from strong sources of heat or mechanical strain to preserve long-term signal quality.
