Network Cable Synergy 21 Patch Cable RJ45 CAT8.1 2000Mhz Black S-STP S/FTP TPE/LSZH SuperFlex

The Synergy 21 Patch Cable RJ45 CAT8.1 2000MHz Black S-STP S/FTP TPE/LSZH SuperFlex is a high-performance network cable designed for environments that require extremely fast and reliable data transmission. Built to support frequencies up to 2000 MHz, this CAT8.1 cable uses S-STP (screened shielded twisted pair) with S/FTP construction to minimize electromagnetic interference and crosstalk. The jacket combines TPE and LSZH materials for enhanced flexibility, durability, and reduced smoke emission in case of fire, making it suitable for both home and professional installations.

Advantages

The cable’s S-STP S/FTP shielding provides improved protection against external interference and maintains signal integrity over short and medium distances. With a SuperFlex TPE/LSZH jacket, the cable resists kinking and remains pliable for easier routing in tight spaces while meeting low-smoke, zero-halogen safety requirements. The CAT8.1 specification and 2000 MHz rating enable higher throughput and lower latency compared to earlier categories, supporting demanding network tasks without introducing unnecessary complexity.

Suitable for

• High-speed data centers and server racks
• Professional AV systems and streaming setups
• Competitive gaming stations and low-latency networks
• Backbone links and switch-to-switch connections
• Environments requiring low smoke and halogen-free materials

Key specifications

• Category: CAT8.1
• Frequency rating: up to 2000 MHz
• Connector type: RJ45
• Shielding: S-STP with S/FTP inner construction
• Outer jacket material: TPE / LSZH (SuperFlex)
• Color: Black
• Primary use: Short-to-medium high-speed copper links

How to use

Connect one RJ45 connector to the network port on your device and the other to the intended switch, router, or patch panel. Ensure connectors are fully seated and that the cable is not bent sharply near the plug to avoid damaging the internal pairs or compromising shielding effectiveness. For optimal performance keep cable runs within recommended lengths for CAT8.1 in your specific installation context and separate the cable from strong electrical noise sources when possible.

Usage recommendations

Use this cable for point-to-point links where maximum bandwidth and shielding are required. Avoid tight coils and sharp bends; secure runs with Velcro straps rather than metal ties to preserve the SuperFlex jacket. Confirm that connected equipment and patch panels support CAT8.1 performance to take full advantage of the 2000 MHz rating.
