Cable de red EFB Elektronik EC020200254 RJ-45 Cat8.1 20 m amarillo

The EFB Elektronik EC020200254 RJ-45 Cat8.1 20 m Yellow is a high-performance networking cable designed for demanding Ethernet environments. It is a 20 m S/FTP Cat8.1 cable with RJ-45 connectors and a conspicuous yellow jacket, intended to deliver reliable high-speed data transmission in structured cabling, server rooms, and professional network installations.

Advantages

The S/FTP shielding provides enhanced protection against electromagnetic interference and crosstalk, supporting stable signal integrity over the cable length. Cat8.1 specification enables significantly higher bandwidth compared with earlier categories, allowing data transfer rates up to 40000 Mbit/s where connected equipment and network infrastructure support these speeds. Gold-plated RJ-45 connectors improve contact quality and resist corrosion, while the 20 m length offers flexibility for placements between network equipment without additional splices.

Suitable for

• High-speed ethernet links in data centres and server rooms
• Backbone cabling and switch-to-switch interconnects
• Workstations and network devices requiring long runs up to 20 meters
• Environments where cable visibility and identification are required

Key specifications

• Category: Cat8.1 (S/FTP)
• Length: 20 m
• Connectors: RJ-45 to RJ-45
• Maximum data transfer rate: up to 40000 Mbit/s (dependent on network equipment)
• Shielding: S/FTP (shielded foiled twisted pair)
• Colour: Yellow

How to use

Connect one RJ-45 connector to the network port of a switch, router, or network interface on a device and the other RJ-45 connector to the corresponding port on the remote device. Ensure connectors are fully inserted until they click to secure the connection. Route the cable to avoid sharp bends, kinks, and sources of strong electromagnetic interference. If running in cable trays or ducts, follow local installation standards for separation from power lines and securing the cable at regular intervals.

Recommendations

For optimal performance, use the cable within its 20 m length rating and pair it with equipment that supports Cat8.1 or compatible high-speed interfaces. Avoid excessive bending radii and protect connectors during installation and transport. When installing in shared conduits, maintain recommended separation from power cables and verify compatibility with existing network hardware to achieve the specified data rates.
