Networking cable Goobay 91664 — Cat7 S/FTP (S‑STP), RJ‑45 to RJ‑45, 25 m, blue

Goobay 91664 is a 25 m Category 7 Ethernet patch cable with S/FTP (S‑STP) shielding and RJ‑45 connectors on both ends. Designed for high-speed LAN, server and switch connections, structured cabling and setups that require reduced crosstalk and improved electromagnetic interference protection, this blue cable supports data transmission up to 10 Gigabit Ethernet and is tested to 600 MHz. The cable uses high-quality copper conductors and gold-plated contacts with a length indication on the strain relief for easier installation and management.

Advantages

The double-shielded S/FTP construction with foil for individual pairs and an overall braid reduces external interference and crosstalk, ensuring stable signal integrity in dense network environments. Gold-plated 50 µ contacts provide reliable plug-in connections and corrosion resistance. Robust latch protection and bend relief on the RJ‑45 plugs reduce the risk of mechanical damage during repeated use. With Cat7 performance and backward compatibility to common Ethernet standards, the cable supports PoE/PoE+ and high-bandwidth applications such as 10 Gbit/s links.

Suitable for

• High-speed LAN connections between switches, routers and servers
• Structured cabling in offices and server rooms
• Gaming consoles and high-resolution streaming (e.g., 4K/120 Hz, 8K/60 Hz)
• Environments with elevated electromagnetic interference where improved shielding is required
• PoE and PoE+ powered devices such as access points and IP cameras

How to use

Connect one RJ‑45 plug to your network device (router, switch, server or modem) and the other plug to the corresponding port on the target device. Ensure connectors click into place to confirm a secure connection; the latch protection reduces the risk of accidental damage. Route the cable avoiding sharp bends and excessive tension; use the length marking on the strain relief to verify cable length during installation. For permanent structured cabling, secure the cable along cable trays or install it according to local wiring standards.

Usage recommendations

For best performance maintain bend radius and avoid running the cable in parallel and close proximity to high-voltage power lines. Use the Cat7 cable for backbone, switch-to-switch or server connections and where enhanced shielding is required; for shorter runs or consumer-grade equipment Cat6A or Cat6 cables remain compatible and may be sufficient.
