Network patch cable Synergy21 S218125 RJ45 CAT6A S/FTP slimline round white 500 MHz 500 m

Synergy21 S218125 is a CAT6A RJ45 network patch cable supplied on a 500 m reel. The cable features S/FTP shielding to minimise crosstalk and external electromagnetic interference, a slimline round white jacket for space-efficient routing, and a 500 MHz rating suitable for high-speed Ethernet and structured cabling applications. The reel format supports extended runs and simplifies installation planning in data centres, server rooms and commercial structured cabling projects.

Advantages

The S/FTP construction combines overall foil shielding with individually shielded pairs to provide enhanced protection against alien crosstalk and external noise while preserving signal integrity at higher frequencies. The slimline round jacket reduces bundle diameter for denser cable trays and conduit fills, helping to optimise space without sacrificing performance. Being rated to 500 MHz, the cable supports higher bandwidth links and future-proofs installations that require robust data throughput and reduced error rates.

Suitable for

• 10 Gigabit Ethernet and other high-speed network connections
• Structured cabling in data centres and server rooms
• Commercial and office network backbones where shielding is required
• Long runs from distribution points using a reel-fed installation

Key specifications

• Cable category: CAT6A
• Connector type: RJ45 compatible
• Shielding: S/FTP (overall foil with individual pair foil)
• Jacket profile: slimline round, white
• Frequency rating: up to 500 MHz
• Length format: 500 m reel

How to use

Plan the cable route and calculate required lengths before deploying the reel to ensure continuous runs without unnecessary splices. Pull the cable from the reel, avoiding sharp bends and exceeding the manufacturer’s recommended bend radius to maintain performance. Terminate each end with compatible RJ45 connectors and follow standard wiring schemes for CAT6A installations. Use appropriate strain relief and cable management accessories in trays or conduit to prevent mechanical stress and maintain shielding continuity.

Usage recommendations

Maintain separation from power cables and strong electromagnetic sources when routing to maximise shielding effectiveness. Test links after termination using a certified network tester for CAT6A to verify continuity, performance and alien crosstalk levels. Store unused reel stock in a dry, temperature-stable environment and handle the cable to avoid kinks or crushing that could impair signal quality.
