Network Cable Synergy 21 S216843V2 RJ45 CAT6A 500Mhz 40m black

The Synergy 21 S216843V2 RJ45 CAT6A 500MHz patch cable, 40 m in length and black finish, is a high-performance network cable designed for demanding wired installations. Constructed with S-STP (S/FTP) shielding and a PUR jacket, the cable supports high-speed data transmission up to 500 MHz while providing improved protection against electromagnetic interference and mechanical wear. Its 40 m length suits longer runs inside buildings or across covered outdoor areas where stable, low-latency connections are required.

Advantages

The S-STP (S/FTP) shielding structure reduces crosstalk and external electromagnetic interference, improving signal integrity in congested or electrically noisy environments. The PUR outer jacket increases resistance to abrasion, oils and mechanical stress compared with standard PVC, extending service life. The CAT6A specification allows for higher bandwidth and better performance at 10 Gigabit Ethernet speeds over copper, while the factory-terminated RJ45 ends ensure consistent connectivity and easy installation.

Suitable for

• 10 Gigabit Ethernet links in office and data center patching
• Longer horizontal runs within buildings and between network closets
• Environments with increased electromagnetic interference such as near industrial equipment
• Temporary outdoor-covered installations and protection-critical indoor routes

Key specifications

• Category: CAT6A, performance up to 500 MHz
• Length: 40 meters
• Connector type: RJ45, shielded
• Shielding: S-STP (S/FTP) — overall braid with individually shielded pairs
• Jacket material: PUR (polyurethane) for enhanced abrasion and chemical resistance
• Color: black
• Designed for indoor and covered outdoor use

How to use

Measure the required run and route the cable avoiding sharp bends and sources of extreme heat. Use appropriate cable management such as trays, conduits or tie points to prevent strain on the connectors. Terminate each end into compatible shielded RJ45 ports or patch panels, ensuring the cable shield is properly grounded at patch panels or connectors to maintain shielding effectiveness. When routing near power lines or heavy machinery, maintain separation distances or add additional shielding measures if necessary.

Usage recommendations

For optimal performance, avoid tight bending radii and kinking; follow the manufacturer’s recommended minimum bend radius. Verify continuity and certification with a network tester after installation to confirm 10G performance and correct pair termination. Ground shielded connectors properly to benefit from the S-STP structure, and choose suitable indoor or covered outdoor pathways to protect the PUR jacket from prolonged direct sunlight or immersion.
