Sieťový kábel EFB Elektronik EC020200276 RJ-45 Cat8.1 20 m zelený

The EFB Elektronik EC020200276 RJ-45 Cat8.1 20 m Green networking cable is a high-performance Ethernet cable designed for fast, low-latency data transmission in demanding network environments. Constructed with S/FTP shielding and gold-plated RJ-45 connectors, this 20 metre cable supports very high data transfer rates and provides robust protection against electromagnetic interference. The green jacket makes cable identification simple in multi-cable installations while maintaining flexible handling for routing and terminations.

Advantages

This Cat8.1 cable delivers up to 40000 Mbit/s data transfer capability under suitable network conditions and is engineered for enhanced signal integrity thanks to S/FTP shielding. Gold-plated RJ-45 connectors reduce corrosion and improve contact quality for consistent connectivity. The 20 m length covers longer runs without repeaters in many setups, and the durable outer jacket and flexible design help simplify installation in racks, cable trays and office or home environments.

Suitable for

• High-speed server-to-switch and switch-to-switch connections
• Data centres and rack wiring where high bandwidth and low latency are required
• Workstations, NAS devices and desktop systems requiring multi-gigabit links
• Structured cabling backbones and horizontal runs in small to medium installations

Key specifications

• Category: Cat8.1 Ethernet cable
• Length: 20 m
• Shielding: S/FTP (shielded foil with overall braid)
• Connectors: RJ-45 to RJ-45 with gold-plated contacts
• Maximum data transfer rate: up to 40000 Mbit/s (subject to network equipment and conditions)
• Color: green
• Conductor arrangement: twisted pairs

How to use

Route the cable between devices ensuring that the RJ-45 connectors are fully inserted into the Ethernet ports until they click. Avoid sharp bends and kinks; maintain the manufacturer’s minimum bend radius where possible. For rack or cabinet installations, secure the cable with appropriate ties or routing accessories to prevent strain on the connectors. Test the link with network test tools or the network equipment port indicators to confirm connectivity and negotiated speeds.

Recommendations

For optimal performance, pair the cable with compatible Cat8-capable switches, NICs and patch panels and minimize exposure to strong electromagnetic sources. In long multi-segment runs or mixed-category environments, verify end-to-end performance with certified testing equipment. Store unused cable coiled loosely to avoid damaging internal pairs.
