Networking Cable Flexline FL31-43155 1.5m Cat8.1 U/FTP Black

The ShiverPeaks Networking Cable Flexline FL31-43155 1.5m Cat8.1 U/FTP Black is a high-performance Ethernet cable designed for demanding network environments. Compliant with Cat8.1 specifications and featuring U/FTP shielding, this 1.5-metre cable supports data transfer rates up to 40000 Mbit/s and is terminated with RJ-45 connectors on both ends. The cable’s construction and shielding help maintain signal integrity in installations where interference or crosstalk could affect performance, while the compact length and black jacket make it suitable for short runs between devices or within rack systems.

Advantages

The cable’s Cat8.1 rating provides a substantial bandwidth increase compared to older categories, enabling faster data throughput and lower latency for compatible equipment. U/FTP shielding (overall braid with individually foiled pairs) reduces electromagnetic interference from nearby cables and devices, improving stability in congested network setups. The RJ-45 terminations ensure compatibility with a wide range of routers, switches, and network adapters that accept modular plugs. Its 1.5 m length minimizes excess cable for tidy installations while the durable outer jacket and connector strain relief offer reliable mechanical protection for frequent plugging and movement.

Suitable for

• Short-distance high-speed links between servers, switches, and routers in data centers or server rooms
• Direct connections for high-bandwidth workstations and high-performance PCs
• Connections where electromagnetic interference is present and shielded cabling is required
• Home or office setups needing a compact, reliable Cat8.1 cable for gigabit and multi-gigabit applications

Key specifications

• Category: Cat8.1
• Shielding: U/FTP (overall braid with individually foiled pairs)
• Length: 1.5 m
• Data transfer rate: up to 40000 Mbit/s
• Connector type: RJ-45 on both ends
• Color: Black

How to use

Connect one RJ-45 plug to the Ethernet port of your source device (switch, router, or network card) and the other RJ-45 plug to the destination device. Ensure connectors are fully inserted until they click to establish a secure connection. For rack or cabinet installations, route the cable to avoid sharp bends and avoid running parallel and close to high-voltage power lines to minimize potential interference. The 1.5 m length is intended for short links; avoid stretching the cable and allow slack for connector movement.

Recommendations

The cable is optimized for short, high-speed connections; use it where Cat8.1 performance is supported by network equipment. For long-distance runs, consider lower-frequency-specific cabling or fiber optics. Inspect connectors before use and avoid tight bends (radius below manufacturer-recommended limits) to preserve shielding effectiveness and overall signal quality.
