Sieťový kábel EFB Elektronik RJ45 S/FTP Cat6a 20 m žltý

The EFB Elektronik RJ45 S/FTP Cat6a networking cable (20 m) is built for reliable high-speed data transmission in structured cabling and device-to-device connections. It uses S/FTP shielding and Category 6a specifications to support broadband signals up to 1000 MHz. The cable comes terminated with two RJ-45 connectors and is halogen-free, with a yellow jacket for easy identification in installations. TIA/EIA 568B wiring is applied for consistent pinout compatibility.

Advantages

S/FTP shielding minimizes electromagnetic interference and crosstalk for stable signal quality. Cat6a rating and 1000 MHz capability allow support for high-throughput applications. The 20 m length covers longer runs without additional patching, while the yellow colour improves visibility and cable management. Halogen-free construction reduces harmful emissions in case of fire.

Suitable for

• Wired Ethernet links in offices and homes
• Connections between switches, routers and servers
• High-bandwidth applications such as streaming, VoIP, and large file transfers
• Structured cabling where TIA/EIA 568B termination is required

How to use

Plug one RJ-45 connector into the network port of your device and the other into the corresponding port on the switch, router or patch panel. Ensure connectors are fully inserted until they click. For best performance, avoid tight bends and keep the cable away from strong sources of electromagnetic interference such as power transformers or high-voltage wiring. Follow standard TIA/EIA 568B practices when integrating the cable into structured cabling.

Recommendations

For optimal signal quality, maintain bend radius greater than four times the cable diameter, avoid running the cable parallel to high-voltage power lines, and check that both ends use proper RJ-45 terminations. Use the yellow colour to separate this run from other networks or services during installation.
