Ethernetový patchkabel Extralink Cat.7 S/FTP 3 m 20 Gbit/s zelený

The Extralink Cat.7 S/FTP 3 m 20 Gbps green patch cable is a shielded copper Ethernet cable designed for high-speed LAN connections in home and office environments. With S/FTP construction (individual pair foils plus an overall braid) and gold‑plated shielded RJ45 connectors, this 3‑metre cable provides improved protection against electromagnetic interference and crosstalk while supporting high data rates and Power over Ethernet (PoE) applications.

Advantages

The S/FTP design delivers enhanced resistance to EMI and minimizes crosstalk, ensuring more stable and reliable data transfer compared with unshielded cables. Cat.7 performance supports higher bandwidth and transmission rates, making the cable suitable for modern network demands such as high-resolution video streaming and heavy file transfers. Its copper conductors and robust connector shielding provide durable connections and compatibility with existing Ethernet equipment.

Suitable for

• Connecting routers, switches and network devices in home and office LANs
• High-bandwidth tasks such as 4K/8K video streaming and large file transfers
• PoE-powered devices like access points, IP cameras and VoIP phones
• Environments with potential electromagnetic interference where shielding is required

Key specifications

• Category: Cat.7 (S/FTP)
• Length: 3 m
• Maximum supported speed: up to 20 Gbps
• Supported frequency: up to 600 MHz
• Conductor material: copper (four twisted pairs)
• Connector type: shielded RJ45 with gold plating
• Shielding: foil around each pair plus overall braided shield

How to use

Plug one end of the Extralink Cat.7 S/FTP cable into the RJ45 port of your router, switch or network device and insert the other end into the target device. Ensure connectors are fully seated and locked to maintain shield continuity. For PoE devices, confirm the switch or injector supports the required power class before connecting. Route the cable avoiding sharp bends and sources of strong electromagnetic fields where possible to preserve signal integrity.

Recommendations

Use the 3 m Extralink Cat.7 cable for short to medium-length indoor connections where shielding and higher bandwidth are required. For long permanent runs, follow installation best practices: maintain bend radius, avoid high-temperature exposure, and verify connector grounding when used in shielded installations.
