Network patch cable Synergy21 S218124 RJ45 Cat6A S/FTP slimline round 500 MHz 500 m white

Synergy21 S218124 is a Cat6A S/FTP network patch cable supplied on a 500 m spool and intended for structured cabling installations that require reliable 10 Gigabit Ethernet performance. The slimline round construction combines a reduced outer diameter with individually shielded twisted pairs and an overall screen to provide up to 500 MHz bandwidth while minimizing crosstalk and electromagnetic interference. This cable is designed for horizontal and backbone runs in offices, server rooms and data centres where high throughput, PoE compatibility and space‑efficient cable management are important.

Advantages

The shielded S/FTP design offers improved protection against alien crosstalk and external EMI compared with unshielded alternatives, helping to maintain consistent signal integrity at higher frequencies. The slimline round jacket reduces cable bulk in trays and conduits and allows for higher cable density without compromising cooling or airflow. On a 500 m spool, the cable is convenient for long runs and bulk deployment, reducing joins and intermediate patch points.

Suitable for

• 10 Gigabit Ethernet (10GbE) horizontal and vertical cabling
• High‑density office and data centre cable trays
• Power over Ethernet (PoE) devices and installations
• Environments with moderate electromagnetic interference
• Structured cabling projects requiring long continuous runs

Key specifications

• Category: Cat6A
• Shielding: S/FTP (individually foil shielded pairs + overall braid/foil)
• Bandwidth: up to 500 MHz
• Conductor: twisted pair copper conductors
• Construction: slimline round jacket for reduced diameter
• Length per spool: 500 m
• Typical use: supports 10GbE and PoE applications

How to use

Install the cable following standard structured cabling practices: route the cable through trays or conduits, avoid sharp bends and excessive pulling tension, and maintain separation from strong electrical sources where possible. Terminate the cable with compatible Cat6A RJ45 shielded connectors and ensure the connector shields are properly bonded to the installation ground to preserve the effectiveness of the S/FTP shielding. When deploying multiple runs, label spool ends and document routes to simplify future maintenance.

Usage recommendations

For optimal performance, keep individual cable bend radii above the manufacturer’s minimum (commonly 4× the cable diameter), limit untwisting of pairs during termination, and use shielded patch panels and connectors in shielded installations. In PoE installations, verify power class and heat dissipation constraints when bundling many runs in the same tray.
