## Summary description

Synergy21 S216421 is a 5 m network patch cable conforming to Cat6a standard with S/FTP (S‑STP) shielding. It features RJ‑45 connectors at both ends and a yellow jacket for easy identification. Suitable for high‑speed Ethernet links, data centers, office LANs and PoE applications where improved alien‑crosstalk and interference protection are required.

## Long description

Synergy21 S216421 is a 5 m Cat6a network patch cable with S/FTP (S‑STP) shielding and RJ‑45 connectors on both ends. The cable’s yellow jacket provides visual identification in patch panels and cable runs. Designed for high‑speed Ethernet links, it supports applications that require improved protection against alien crosstalk and electromagnetic interference, while remaining compatible with standard RJ‑45 ports and Power over Ethernet deployments.
Advantages
The S/FTP (S‑STP) construction combines an overall foil shield with individually shielded twisted pairs to reduce near‑end and alien crosstalk and to improve immunity to external electromagnetic interference. Cat6a performance supports 10 Gigabit Ethernet across shorter structured cabling runs. The molded RJ‑45 connectors ensure reliable mating and strain relief, and the 5 m length offers a practical balance between reach and cable management within racks, workstations and networking closets.
Suitable for
 10 Gigabit Ethernet links in data centers and server rooms
 Office LAN patching between switches, patch panels and workstations
 Power over Ethernet (PoE) devices such as IP phones and access points
 Environments with elevated electromagnetic interference where additional shielding is required
Key specifications
 Category: Cat6a performance class
 Shielding: S/FTP (overall foil + individually shielded twisted pairs)
 Connector type: RJ‑45 to RJ‑45, 8P8C
 Length: 5 meters
 Jacket color: yellow for easy identification
 Cable usage: suitable for Gigabit and 10 Gigabit Ethernet and PoE
How to use
Install the Synergy21 Cat6a patch cable by plugging the RJ‑45 connector into the network ports of switches, patch panels, routers or networked devices until the latch clicks. Route the cable to avoid sharp bends and excessive tension; maintain bend radius recommendations typical for Ethernet patch cords. For structured cabling, use labeled patch panels or color‑coded management to keep the yellow cable easily traceable. Verify link speed and PoE operation after connection using network diagnostics or device indicators.
Usage recommendations
For best performance, avoid running the cable parallel to power lines and large electrical equipment. Use the yellow jacket as part of a color‑coding scheme to separate circuits or services. Replace the cable if connector clips are damaged or if the cable shows visible wear that could affect shielding integrity.
