Networking Cable Tecline 71803S Black 3m Cat6a S/FTP

The Tecline 71803S Black 3m Cat6a S/FTP networking cable is a shielded Ethernet lead designed for reliable high-speed data transfer over a 3‑metre reach. Built to Cat6a performance class and featuring S/FTP construction (overall shield plus individually shielded pairs), the cable reduces electromagnetic interference and crosstalk for stable connections in home and office networks. Terminated with standard RJ‑45 connectors on both ends, the cable supports devices that use 8P8C ports and is suitable for modern wired network environments where consistent throughput is required.

Advantages

S/FTP shielding provides enhanced protection against external noise and internal pair interference, improving signal integrity at higher frequencies. Cat6a specification allows for reliable 10 Gigabit Ethernet performance at shorter to medium runs and offers better return on investment for infrastructure upgrades. The 3 m length balances flexibility and tidiness, while black jacket material offers a neutral appearance that integrates with most installations. Durable connector boots and strain relief reduce wear at termination points to extend service life.

Suitable for

• Connecting desktop PCs, laptops and network switches in home or small office setups
• High-bandwidth applications such as video streaming, online gaming and large file transfers
• Temporary or permanent links between routers, patch panels and networked devices
• Environments with potential electromagnetic interference from nearby equipment

Key specifications

• Category: Cat6a (augmented Cat6) for improved high-frequency performance
• Shielding type: S/FTP — overall foil shield plus individually foil-shielded twisted pairs
• Length: 3 metres
• Connector type: RJ-45 (8P8C) on both ends
• Color: Black jacket
• Intended speeds: up to 10 Gbps at recommended distances for Cat6a
• Suitable frequency range: up to 500 MHz typical for Cat6a

How to use

Plug one RJ‑45 connector into the Ethernet port of your modem, router, switch or network device and the other connector into the corresponding port of the target device. Ensure connectors are inserted until the clip clicks to secure the connection. Route the 3 m cable to avoid kinks or tight bends and keep it away from heavy power cables to minimize possible interference. For patch panel installations, fully insert the RJ‑45 and verify link/activity LEDs on network equipment to confirm a live connection.

Usage recommendations

For consistent 10 Gbps performance, use the Tecline Cat6a cable for direct device-to-switch connections or within structured cabling segments under 100 metres, and avoid running the cable parallel and close to high-voltage power lines. Periodically inspect connectors and jacket for damage; replace the cable if shielding or connector integrity is compromised.
