Networking cable EFB Elektronik K8708BL.20 RJ-45 Cat6a 20 m Blue

The EFB Elektronik K8708BL.20 RJ-45 Cat6a 20 m Blue is a 20-metre network cable designed to deliver high-speed wired connectivity for home and office networks. Built to Cat6a standard with S/FTP shielding and gold-plated RJ-45 connectors, the cable supports data rates up to 10000 Mbit/s and is intended for reliable transmission in environments where higher bandwidth and reduced interference are required.

Advantages

This Cat6a cable combines S/FTP shielding with twisted-pair construction to minimise crosstalk and electromagnetic interference. Gold-plated RJ-45 contacts improve contact reliability and corrosion resistance, while the 20 m length provides flexibility for connecting distant devices without additional extensions. The blue jacket offers easy visual identification within multi-cable installations.

Suitable for

• High-speed Ethernet links (up to 10 Gbps) in local area networks
• Wiring between routers, switches, patch panels and networked devices
• Home offices and small business network setups requiring longer cable runs
• Environments where reduced electromagnetic interference is important

Key specifications

• Standard: Category 6a (Cat6a)
• Shielding: S/FTP (overall shield plus individually shielded pairs)
• Connectors: RJ-45 to RJ-45 with gold-plated contacts
• Maximum data rate: up to 10000 Mbit/s (10 Gbps)
• Length: 20 m
• Colour: Blue

How to use

Uncoil the 20 m cable and route it along the planned path avoiding sharp bends and sources of strong electromagnetic interference. Insert the RJ-45 connector firmly into the network ports of devices such as routers, switches, computers or patch panels until the connector latch clicks. For long-term installations, secure the cable with cable ties or clips and leave service loops where access for maintenance is required. Ensure both ends are connected to compatible Gigabit or 10 Gigabit ports to attain the cable's maximum throughput.

Recommendations

Avoid running the cable parallel to mains power lines or close to large motors and fluorescent lighting to minimise interference. Do not exceed recommended bend radius and avoid kinking; store the cable coiled without tight loops. For structured cabling, label both ends for easier identification and consider testing with a cable tester after installation to verify continuity and performance.
