Cable de red EFB Elektronik K5547SW.0,25 RJ-45 Cat6a 0,25 m negro

The EFB Elektronik K5547SW.0,25 RJ-45 Cat6a 0.25 m cable is a compact patch cable designed for high-speed Ethernet connections. Complying with the Cat6a standard and supporting 10GBase-T, this short black cable delivers data rates up to 10000 Mbit/s and includes U/FTP shielding to minimise crosstalk and external electromagnetic interference. The cable is fitted with standard RJ-45 connectors on both ends and is intended for short link connections in structured cabling and network equipment patching.

Advantages

The cable’s Cat6a specification and 10GBase-T compatibility provide reliable high-bandwidth performance for demanding network segments. U/FTP shielding reduces signal degradation in environments with potential electromagnetic interference, while the short 0.25 m length helps to prevent cable clutter and maintain tidy patch panels or switch-to-device connections. The black jacket offers a neutral, professional appearance suitable for server rooms and office installations.

Suitable for (tasks / use cases)

• Short-distance patching between switches, routers and servers
• Connecting network devices in dense rack environments
• High-speed 10GBase-T links for data transfers and backups
• Workstation or desktop connections where minimal cable slack is needed

Key specifications

• Cabling standard: Cat6a
• Data rate support: up to 10000 Mbit/s (10 Gbit/s)
• Cabling technology: 10GBase-T
• Shielding: U/FTP (shielded pairs with overall braid/foil as applicable)
• Connectors: RJ-45 to RJ-45
• Cable length: 0.25 m
• Colour: Black

How to use

Plug each RJ-45 connector into the corresponding Ethernet ports on your devices, such as switches, routers, servers or network interface cards. Ensure connectors click into place to secure the link. Use this 0.25 m cable for short, direct connections to avoid excess slack; it is not intended for long-distance runs. If used in a rack, route the cable neatly to avoid strain on the connectors and to maintain airflow.

Recommendations

For optimal performance, use the cable in shielded or properly grounded installations when connecting to other shielded components. Avoid tight bends and mechanical stress; maintain bend radii recommended for Cat6a cabling. Verify link speed and duplex settings on connected devices to ensure operation at the desired 10GBase-T rates.
