Networking Cable EFB Elektronik EC020200243 RJ-45 Cat8.1 20 m Blue

The EFB Elektronik EC020200243 RJ-45 Cat8.1 20 m Blue is a high-performance networking cable designed for environments that require very high data throughput and robust shielding. This Cat8.1 cable supports data transfer rates up to 40000 Mbit/s and uses S/FTP shielding to reduce electromagnetic interference. It is fitted with gold-plated RJ-45 connectors on both ends and comes in a 20 metre length with a blue jacket for easy identification in installations.

Advantages

The cable's S/FTP construction combines an overall foil shield with individually shielded pairs to provide strong protection against crosstalk and external noise. Gold-plated RJ-45 connectors improve contact reliability and resist corrosion, helping to maintain stable connections over time. With Cat8.1 specification, the cable is suitable for high-bandwidth applications and supports future-proofed network setups where low latency and high throughput are required.

Suitable for

• Data centres and server rooms requiring high-speed uplinks
• High-bandwidth workstations and professional AV installations
• Backbone connections within structured cabling systems
• Environments with significant electromagnetic interference

Key specifications

• Cable category: Cat8.1
• Length: 20 m
• Shielding: S/FTP (overall foil + individually shielded pairs)
• Maximum data rate: up to 40000 Mbit/s
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Colour: Blue

How to use

Connect each RJ-45 connector to standard Ethernet ports on network equipment such as switches, routers, patch panels or network interface cards. Route the cable along designated cable channels or trays, avoiding tight bends and sharp edges to preserve shielding integrity and signal performance. For installations in environments with high interference, ensure proper grounding of connected equipment and maintain secure connector seating to prevent intermittent contact.

Recommendations

For optimal performance, avoid bending the cable below its minimum bend radius and keep it separated from high-voltage power lines. Use the 20 m length to minimize the number of intermediate connections; if additional runs are required, use compatible Cat8.1 components and properly rated patch panels to maintain overall link performance.
