Networking Cable EFB Elektronik K5525FBL.25 25m Cat6a S/FTP

The EFB Elektronik K5525FBL.25 is a 25 m networking cable built to the Cat6a standard with S/FTP shielding and gold-plated RJ-45 connectors. Designed for installations that require higher bandwidth and reduced interference, this blue cable supports data transfer rates up to 10000 Mbit/s and provides a reliable physical connection between network devices over a longer run.

Advantages

S/FTP shielding (overall foil with individually shielded pairs) reduces crosstalk and electromagnetic interference compared with unshielded cables, helping to maintain signal integrity in environments with multiple cables or nearby electronic equipment. The Cat6a specification supports higher frequencies and data rates, while gold-plated RJ-45 connectors offer improved contact reliability and corrosion resistance for stable long-term connections. The 25 m length provides flexibility for rack-to-desk, patch panel runs, or longer point-to-point connections without intermediate joints.

Suitable for

• Wired Ethernet connections in offices, server rooms, and homes
• Connecting switches, routers, patch panels, and network endpoints
• Installations requiring reduced electromagnetic interference and high data throughput
• Applications needing a 25 m Cat6a cable with reliable RJ-45 termination

Key specifications

• Cable length: 25 m
• Standard: Cat6a
• Shielding: S/FTP (overall foil with individually shielded pairs)
• Maximum supported data rate: up to 10000 Mbit/s
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Colour: Blue

How to use

Connect one gold-plated RJ-45 connector to the network port of your switch, router, or patch panel and the other connector to the target device. Ensure that connectors are fully inserted until the latch clicks to secure the connection. When running the cable through conduit or cable trays, avoid sharp bends and maintain the manufacturer’s recommended bend radius to preserve performance. For installations in environments with significant sources of electromagnetic interference, ensure proper grounding of adjacent infrastructure when required by local wiring standards.

Usage recommendations

For optimal performance, use the cable within its 25 m length without excessive twisting or tight bends, and verify end-to-end connections after installation. When integrating into structured cabling systems, pair this Cat6a S/FTP cable with compatible shielded patch panels and connectors to retain shielding continuity.
