Networking Cable Renkforce RF-4538186 0.5m Cat8.1 F/FTP Black

The Renkforce RF-4538186 0.5m Cat8.1 F/FTP networking cable is a short, high-performance Ethernet lead designed for environments where maximum data throughput and minimal interference are required. This cable uses the Cat8.1 specification with F/FTP shielding and gold-plated RJ-45 connectors to provide reliable connections for modern network devices. Its compact length of 0.5 metres makes it suitable for connecting equipment in racks, between switches and servers, or linking devices on a desktop with minimal cable clutter.

Advantages

F/FTP shielding around each twisted pair and an overall foil wrap reduce crosstalk and electromagnetic interference, helping to maintain signal integrity at high frequencies. The Cat8.1 standard supports very high data rates and improved transmission performance compared with lower-category cables. Short cable length minimizes latency and signal degradation, while RJ-45 terminations ensure compatibility with standard Ethernet ports. Durable outer jacket and robust connector housings provide mechanical stability in typical office and server-room setups.

Suitable for

• High-speed connections between switches, routers and servers in data centers or network closets
• Short-distance links in home or office workstations where a tidy installation is needed
• Applications requiring low interference such as streaming, large file transfers and virtualized environments

Key specifications

• Category: Cat8.1 performance class suitable for high-frequency transmission
• Shielding: F/FTP (foil around all pairs and foil around each twisted pair)
• Connectors: RJ-45 on both ends with gold-plated contacts for reliable contact
• Length: 0.5 metres (short patch cable for close equipment placement)
• Maximum supported data rate: up to 40000 Mbit/s as per product performance
• Color: black with a durable outer jacket

How to use

Connect one RJ-45 plug to the Ethernet port of the source device (for example a switch or router) and the other plug to the destination device (server, workstation or network appliance). Ensure that both connected devices support the intended network speed and that ports are clean and undamaged before insertion. Because this is a short-length cable, route it to avoid sharp bends and mechanical stress on the connectors; secure with cable ties or clips if necessary to prevent tension on the terminations.

Usage recommendations

For optimal performance, use this Cat8.1 F/FTP cable for short, high-bandwidth connections in controlled environments such as racks or desktop setups. Avoid running the cable parallel to high-voltage power lines and maintain gentle bend radii to preserve the shielding and pair geometry. Verify device port configurations and network settings to make full use of the supported data rates.
