Network Cable Synergy 21 S216840V2 RJ45 CAT6A 500Mhz 20m Black

The Synergy 21 S216840V2 RJ45 CAT6A 500Mhz 20m Black patch cable provides a 20-metre connection designed for high-speed Ethernet links up to 500 MHz. It uses CAT6A specifications and an RJ45 connector to support 10 Gigabit Ethernet over copper where cable performance and signal integrity are important. The cable construction includes S-STP (S/FTP) shielding and a durable PUR jacket that offer improved protection against electromagnetic interference and mechanical wear, suitable for both fixed installations and flexible routing in indoor and sheltered outdoor environments.

Advantages

S-STP S/FTP shielding minimizes crosstalk and external interference, supporting stable high-bandwidth transmission. The CAT6A specification and 500 MHz rating enable reliable 10 Gigabit performance at relevant distances. A PUR outer jacket improves resistance to abrasion, chemicals and bending, while maintaining flexibility for easier installation and cable management. The 20 m length covers longer runs without additional patching, and the black finish provides a discreet appearance in racks and visible installations.

Suitable for

• 10 Gigabit Ethernet connections in offices and data rooms
• Structured cabling backbones and switch-to-switch links
• High-density network environments where interference reduction is required
• Temporary or permanent runs requiring a flexible, durable cable up to 20 m

Key specifications

• Frequency rating: 500 MHz
• Connector type: RJ45
• Shielding: S-STP (S/FTP) — overall braid with individually foil-shielded pairs
• Length: 20 m
• Jacket material: PUR (polyurethane) for enhanced durability and flexibility
• Color: Black
• Suitable for indoor and sheltered outdoor use

How to use

Connect the RJ45 plugs to the corresponding Ethernet ports on network devices such as switches, routers or network interface cards. Ensure connectors are fully inserted until the latch clicks to establish a secure physical connection. Route the cable to avoid sharp bends, excessive tension or sources of strong electromagnetic noise; maintain minimum bend radius consistent with CAT6A handling recommendations. Test the link with appropriate network testing tools to verify performance and certify cabling if required.

Usage recommendations

For optimal performance, use the cable within its rated distance and avoid running it parallel to high-voltage power lines. When installing in structured cabling, keep patch cables separate from permanent cabling or follow local installation standards. Periodically inspect connectors and jacket for wear, and replace the cable if shielding or mechanical integrity is compromised.
