Sieťový kábel Helos 263821 20 m Cat6a S/FTP biely

The Helos 263821 20m Cat6a S/FTP networking cable is a shielded ethernet cable engineered for high-speed wired connections. With a 20 m length and Cat6a performance class, this cable supports demanding data transmission scenarios. Gold-plated RJ-45 connectors at both ends ensure a reliable contact interface and help reduce contact corrosion and signal loss. The white outer jacket provides a neutral, unobtrusive appearance for home or office installations.

Advantages

The S/FTP shielding construction combines overall foil shielding with individually shielded pairs to reduce electromagnetic interference and crosstalk in environments with multiple adjacent cables or electronic equipment. Cat6a specification supports higher bandwidth and improved performance compared with earlier categories over the same distance. Gold-plated RJ-45 connectors enhance connector durability and maintain consistent signal transmission. The 20 m length allows flexible placement of devices across larger rooms without additional patching.

Suitable for

• Wired connections between switches, routers and computers in home networks
• Office workstations and small server setups requiring stable Ethernet links
• High-bandwidth applications such as video streaming, VoIP and file transfers
• Situations where electromagnetic interference needs to be minimized

Key specifications

• Cable length: 20 m
• Cable category: Cat6a
• Shielding: S/FTP (overall foil plus individually shielded pairs)
• Connectors: RJ-45 to RJ-45
• Connector plating: gold-plated contacts
• Colour: White

How to use

Route the Helos Cat6a cable between network devices ensuring the connectors are fully inserted into RJ-45 ports until the latch clicks. Avoid tight bends and kinks; maintain a gentle bend radius to preserve cable performance. If running the cable alongside power lines or other sources of interference, maintain separation where possible despite the S/FTP shielding. Secure the cable with clips or cable ties in a way that does not compress the jacket excessively. Test the link after installation to verify connectivity and expected data rates.

Recommendations

For optimal results, use this Cat6a S/FTP cable for permanent or semi-permanent wired installations where reduced interference and consistent high-speed performance are required. If routing through conduits or behind walls, confirm the cable meets any local fire and building codes and avoid sharp bends or mechanical stress during installation.
