SYNERGY21 S217912 CAT6A S/FTP Slim Patch Cable, RJ45, 0.25m, Black, LSZH

In high-density network environments, bulky cables obstruct airflow, complicate cable management, and increase the risk of accidental disconnections. The SYNERGY21 S217912 CAT6A patch cable solves these challenges with an ultra-slim 4.5 mm round profile and superflex TPE/LSZH jacket that bends easily in tight spaces. Despite its compact size, it delivers full 10 Gigabit Ethernet performance up to 500 MHz, making it ideal for data centers, server rooms, and structured cabling systems where space is at a premium and reliability is non-negotiable.

Who is it for

This cable is engineered for IT professionals, network administrators, and system integrators who manage high-density patching fields, blade servers, or switch-to-server connections. It is equally suitable for enterprise office networks where neat, low-profile cabling is required without sacrificing CAT6A performance. If you need a short, flexible, and durable patch lead that maintains signal integrity in congested racks, this is the right choice.

Main features

• CAT6A performance with 500 MHz bandwidth supports 10GBASE-T Ethernet.
• S/FTP shielding (braided screen plus foil per pair) ensures superior immunity to EMI and alien crosstalk.
• Slimline round design with only 4.5 mm outer diameter saves space and improves airflow.
• Superflex TPE/LSZH jacket offers exceptional flexibility and low smoke, zero halogen safety.
• 28 AWG stranded copper conductors allow tighter bend radii without performance loss.
• Constructed with CAT7 raw cable for enhanced headroom and reliability.
• Short 0.25 m length reduces excess cable slack and clutter.

Tips

For best performance, avoid sharp bends immediately behind the connector; maintain a minimum bend radius of approximately four times the cable diameter (about 18 mm). When patching high-density switches, use vertical cable managers to route these slim cables neatly and preserve airflow. This cable is ideal for short links between adjacent patch panels and equipment, reducing signal loss and improving rack aesthetics.
