Sieťový kábel EFB Elektronik EC020200273 RJ-45 Cat8.1 7,5 m zelený

The EFB Elektronik EC020200273 RJ-45 Cat8.1 networking cable is a 7.5 m green cable designed for high-speed wired connections. Compliant with the Cat8.1 standard, the cable supports data transfer rates up to 40000 Mbit/s and is fitted with gold-plated RJ-45 connectors and S/FTP shielding to maintain signal integrity over short to medium distances. Its robust construction and bright green jacket make it suitable for visible installations where identification and performance matter.

Advantages

The cable’s Cat8.1 specification delivers very high bandwidth and low latency suitable for demanding network environments. S/FTP shielding reduces electromagnetic interference and crosstalk, improving connection stability in crowded cable bundles and near electronic equipment. Gold-plated RJ-45 connectors provide corrosion resistance and consistent contact quality, while the 7.5 m length offers flexibility for routing between devices without excessive slack.

Suitable for

• High-speed Ethernet links between switches, routers and servers in small office or home lab setups
• Backbone or aggregation segments within compact network racks where short, high-capacity runs are required
• Connections for bandwidth-intensive applications such as large file transfers, virtualization hosts and media streaming
• Visible cable runs where color-coding or easy identification is needed

Key specifications

• Standard: Cat8.1
• Maximum data rate: up to 40000 Mbit/s
• Connector type: RJ-45 to RJ-45
• Shielding: S/FTP (shielded/foiled twisted pair)
• Length: 7.5 m
• Outer colour: green
• Contact plating: gold-plated contacts

How to use

Connect one RJ-45 end to a compatible network port on a switch, router, server or network interface card and the other end to the destination device. Ensure connectors are fully seated and locking tabs engage to prevent accidental disconnection. Route the cable to avoid sharp bends and sources of strong electromagnetic interference; maintain recommended bend radius for twisted-pair cables to preserve performance. For rack installations, secure the cable with appropriate cable management accessories to reduce strain on connectors.

Recommendations

Use this Cat8.1 cable for short to medium runs where maximum throughput and minimal interference are required. Avoid running the cable in parallel with high-voltage power lines for extended distances and inspect connectors periodically for secure contact. For permanent installations in demanding environments, combine this cable with proper patch panels and shielded equipment to take full advantage of S/FTP shielding.
