Sieťový kábel EFB Elektronik Cat5e RJ-45 20 m čierny

The EFB Elektronik Cat5e SF/UTP networking cable, 20 m in length and fitted with RJ-45 connectors on both ends, is designed for reliable copper Ethernet connections. The cable uses Cat5e specification with foil and braid (SF/UTP) shielding and a PVC jacket, providing stable signal transmission and reduced electromagnetic interference. The black sheath offers a discreet appearance suitable for home and office installations, and the molded boots improve connector protection and handling.

Advantages

SF/UTP construction with foil and braid shielding lowers crosstalk and external interference compared with unshielded cables, supporting clearer data transmission in environments with electrical noise. The molded boot design increases strain relief at the connector and facilitates plugging and unplugging in high-density applications. TIA/EIA 568B wiring coding ensures compatibility with standard installations, while the printed length marking on the boot helps with quick identification during setup and maintenance.

Suitable for

• Ethernet connections in home networks and small office environments
• Structured cabling runs within equipment racks and wall outlets
• Connections to switches, routers, patch panels and network devices
• Environments with moderate electromagnetic interference where shielded cable is preferred

How to use

Connect one RJ-45 end to your network device (router, switch, computer or patch panel) and the other end to the corresponding port. Ensure connectors are fully inserted until the latch clicks to secure the connection. Route the cable to avoid sharp bends and areas of high mechanical stress; maintain gentle curves to preserve internal pair geometry. If using in a structured cabling run, follow your site’s installation practices for cable support and separation from power lines.

Recommendations

For optimal performance, use this Cat5e SF/UTP cable in setups that require reduced interference and reliable 100BASE-TX or 1000BASE-T links. Avoid running the cable parallel to mains power cables where possible and observe minimum bend radius guidelines. Regularly inspect connectors and boots for wear in high-traffic installations and replace the cable if shielding or jacket damage is visible.
