Networking Cable EFB Elektronik K5545SW.0,25 RJ-45 Cat6a 0.25 m Black

The Networking Cable EFB Elektronik K5545SW.0,25 RJ-45 Cat6a 0.25 m Black is a short patch cable designed for reliable high-speed Ethernet connections. Meeting the Cat6a specification, this 0.25 m cable supports data transfer rates up to 10000 Mbit/s and uses RJ-45 connectors on both ends. The cable employs U/FTP (STP) shielding to reduce electromagnetic interference and crosstalk in dense cabling environments, and its black jacket provides a discrete, professional appearance.

Advantages

This Cat6a patch cable provides high bandwidth suitable for 10 Gigabit Ethernet over short distances and features foil-shielded twisted pairs with an overall shield to improve signal integrity. The compact 0.25 m length minimizes unnecessary cable slack in rack, switch-to-router, or patch panel connections. Durable RJ-45 connectors ensure stable contact and frequent plug cycles, while the black outer jacket resists abrasion and maintains a tidy visual layout in professional installations.

Suitable for

• Connecting switches, routers, patch panels, and servers in data centers and network racks
• Short patch connections between network devices in server rooms and telecommunications cabinets
• High-speed Ethernet links requiring Cat6a performance and shielding in electrically noisy environments

Key specifications

• Cable category: Cat6a
• Length: 0.25 m
• Connectors: RJ-45 to RJ-45
• Shielding: U/FTP (individually foil-shielded pairs with overall shield)
• Maximum data rate: up to 10000 Mbit/s
• Colour: Black

How to use

Use the cable to connect compatible RJ-45 network ports on switches, routers, patch panels, or network interface cards. Ensure both ends are fully inserted until the connector latch clicks to secure the connection. Route the cable to avoid sharp bends or compression; maintain bend radii recommended for twisted-pair cables to preserve transmission performance. For best results, use in short-distance patching applications where a 0.25 m length reduces excess cable and simplifies cable management.

Usage recommendations

Install this Cat6a U/FTP cable in environments where shielding against EMI is required and where short, direct connections between equipment are needed. Avoid running the cable parallel to high-voltage power lines for extended distances and verify connectors and ports are free of dust before insertion. For long-term reliability, inspect connectors periodically and replace the cable if connector contacts or the jacket show visible wear.
