Network patch cable bkl electronic 144037 RJ45 CAT8.1 S/FTP 2 m halogen-free black

bkl electronic 144037 is a 2 m RJ45 patch cable that conforms to the CAT8.1 specification. It features S/FTP shielding and a halogen-free black jacket, designed to provide high-speed Ethernet connectivity for data centers, server racks, and structured cabling environments. The cable supports reduced electromagnetic interference and is suitable for 25/40 Gbps class links where a short, high-performance patch connection is required.

Advantages

The S/FTP construction combines individual pair foil shielding with an overall braid to minimise crosstalk and external interference, helping to maintain signal integrity at high frequencies. The halogen-free jacket reduces harmful gas emissions in case of fire and supports installations where low-smoke, low-toxicity materials are required. A slim, flexible design and standard RJ45 terminations allow easy installation in patch panels, switches and servers while keeping cable management tidy.

Suitable for

• Short links between switches, patch panels and servers in data centers
• High-speed Ethernet connections up to 25/40 Gbps class for CAT8.1-compliant systems
• Structured cabling installations requiring S/FTP shielding and halogen-free materials

When it may not be suitable

This 2 m patch cable is intended for short, in‑rack or cabinet connections and is not designed for long-distance backbone runs or outdoor burial. It may be unnecessary for simple home networks or installations that do not require CAT8.1 performance, where lower-category cables (CAT5e/CAT6/CAT6A) would be more cost-effective.

Key specifications

• Cable length: 2 m
• Connector type: RJ45 to RJ45
• Category: CAT8.1
• Shielding: S/FTP (foil on each pair with overall braid)
• Jacket material: halogen-free
• Colour: black
• Intended use: short high-speed patch connections in racks and cabinets

How to use

Insert each RJ45 plug into the corresponding port on network equipment such as switches, patch panels or servers until the latch clicks. Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius to preserve performance. Use cable management—tray, ties or Velcro straps—to secure the cable and avoid tight bundling with power lines to reduce potential interference. For best results, test links after installation with appropriate network testers to verify performance and continuity for the intended application.

What to consider before purchase

• Required link length and whether a 2 m patch cable meets rack layout needs
• Whether CAT8.1 performance and S/FTP shielding are necessary for the network
• Compatibility with existing RJ45 ports and the space available for cable routing
• Environment requirements such as halogen-free material for safety standards

Usage recommendations

Use this cable for short, high-speed connections inside racks and cabinets. Keep runs as short as practical, avoid close parallel routing with power cabling, and secure cables to prevent stress on connectors. Verify performance after installation with link certification or diagnostic tools appropriate for CAT8.1 systems.
