Synergy21 CAT6A S/FTP Slim Patch Cable, 3m, Black, 500MHz, LSZH Superflex, RJ45

For high-density 10 Gigabit Ethernet patching where space is at a premium, this Synergy21 slimline patch cable delivers full CAT6A performance in a remarkably thin 4.5 mm profile. Built around a premium CAT7 raw cable with S/FTP shielding (foil around each pair plus an overall braid), it suppresses alien crosstalk and EMI far more effectively than standard UTP or single-shielded alternatives. The result is a dependable 500 MHz link that maintains signal integrity even in crowded racks, server rooms, and structured cabling systems.

Highlights

• CAT6A performance: 500 MHz bandwidth, supports 10GBASE-T up to 100 m (this cable is 3 m)
• S/FTP shielding: individual pair foils plus overall braid for maximum noise immunity
• Slimline round design: only 4.5 mm diameter, ideal for high-density patch panels and cable management
• Superflex TPE/LSZH jacket: halogen-free, flame-retardant, and highly flexible for easy routing
• AWG28 stranded copper conductors: excellent flexibility without compromising signal quality
• Snagless molded RJ45 connectors with gold-plated contacts for reliable, long-lasting connections
• Backward compatible with CAT6, CAT5e, and CAT5 networks

In daily use

The slim, round construction and Superflex jacket make this cable exceptionally easy to handle in tight spaces. It bends smoothly around corners, fits through narrow cable managers, and reduces airflow obstruction in densely packed racks. The black LSZH jacket not only meets fire safety requirements for public buildings but also resists wear and tear. Whether you're connecting a high-performance workstation, a PoE++ device, or a switch-to-server link, this patch cable provides a stable, high-speed connection with minimal crosstalk.
