## Summary description

Synergy21 S216501 is a 25 m Cat6a Ethernet cable with S/FTP (S-STP) shielding and RJ-45 connectors at both ends. Designed for high-speed 10 Gigabit networks, the shielded pairs reduce crosstalk and electromagnetic interference. Suitable for office and data-centre patching, structured cabling and connections between network devices where Cat6a performance and improved signal integrity are required.

## Long description

Synergy21 S216501 Cat6a S/FTP (S-STP) is a 25 m black Ethernet cable with RJ-45 connectors at both ends, engineered for 10 Gigabit networks and demanding wired installations. The cable uses individually foil-shielded twisted pairs with an overall braid shield to reduce alien crosstalk and electromagnetic interference, enabling stable high-speed transmission over standard horizontal and patching distances. Its Cat6a rating supports applications that require enhanced bandwidth and signal integrity compared with lower-category cables.
Advantages
The S/FTP (S-STP) construction combines pair-level foil shielding and an overall braided shield to provide robust protection against external interference and near-end crosstalk. The 25 m length offers flexibility for office layouts, rack-to-desk connections, and data-centre patching without excessive slack. Factory-terminated RJ-45 plugs ensure compatibility with standard network equipment and simplify installation. The cable's Cat6a specification supports 10 Gigabit Ethernet performance and improved NEXT and PSNEXT characteristics versus Cat5e/Cat6.
Suitable for
10 Gigabit Ethernet backbones and horizontal links within office and data-centre environments
Patch panel to switch connections and rack-to-rack or rack-to-equipment cabling
Environments with moderate to high electromagnetic interference, such as near power equipment or dense cabling trays
Structured cabling installations requiring future-proof Cat6a performance
Key specifications
Category: Cat6a, suitable for 10 Gbps Ethernet
Shielding: S/FTP (each pair foil-shielded) with overall braided shield
Length: 25 metres
Connectors: RJ-45 to RJ-45, factory-terminated
Colour: Black
Conductor: Twisted-pair copper, suitable for standard Ethernet signalling
How to use
Route the cable between devices or through structured cabling pathways avoiding sharp bends and pinch points. When connecting to patch panels or network ports, fully insert the RJ-45 plugs until they latch; verify link lights on connected equipment to confirm proper connection. For installations within racks or cable trays, maintain recommended bend radii and separate power and signal cabling where possible to maximise shielding effectiveness. If trimming is required, use appropriate cable tools and reterminate with compatible RJ-45 plugs or keystone jacks designed for shielded cables.
Usage recommendations
For optimal performance, install the cable according to Cat6a guidelines, maintain distance from high-voltage power lines, and ensure shields are properly grounded at termination points where applicable. Use the cable for critical links where 10 Gbps throughput and reduced interference are required.
