Networking Cable Wirewin VKW SFTP K7A LSOH3 1000SX 1000m Cat7a S/FTP

The Wirewin VKW SFTP K7A LSOH3 1000SX is a Cat7a networking cable supplied on a 1000 m reel, designed for high-speed, high-reliability data transmission in professional and commercial installations. It combines S/FTP (shielded foil around each pair plus an overall braided shield) construction with an LSOH3 outer sheath to reduce electromagnetic interference and limit smoke and halogen emissions in the event of fire. The cable supports applications requiring enhanced bandwidth and improved signal integrity over long runs.

Advantages

The S/FTP structure provides individual pair shielding plus an overall shield to minimize crosstalk and external interference, improving performance in dense cable environments. The Cat7a standard enables operation at higher frequencies and supports higher data rates compared with lower category cables. The LSOH3 jacket material reduces the release of toxic gases and smoke, making the cable suitable for indoor use in areas with human occupancy and strict safety requirements. A 1000 m reel format facilitates long continuous runs and reduces the need for frequent joins.

Suitable for

• Enterprise LAN backbones and horizontal cabling where high bandwidth is required
• Data centers and server rooms with dense cable routing and EMI concerns
• Commercial buildings, conference facilities, and AV installations
• Environments requiring low-smoke, low-halogen materials for enhanced safety

Key specifications

• Category: Cat7a (Class F) performance suitable for high-frequency applications
• Shielding: S/FTP — individual foil shielding per pair plus overall braided shield
• Length: 1000 m reel for continuous cabling runs
• Jacket material: LSOH3 (Low Smoke Zero Halogen) outer sheath
• Conductor: multi-pair twisted copper conductors designed for balanced transmission
• Suitable frequency: designed for extended frequency range typical of Cat7a cabling

How to use

Install the cable using standard structured cabling practices for shielded twisted pair systems. Maintain correct grounding and bonding for the overall shield and use compatible shielded connectors and patch panels to preserve the S/FTP performance. Avoid sharp bends and excessive tensile force during pulling to prevent damage to conductors and shielding. Cut and terminate the cable with tools designed for shielded categories and verify continuity and performance with appropriate certification testers after installation.

Usage recommendations

Use the Wirewin VKW SFTP K7A LSOH3 cable in installations where high bandwidth and reduced interference are priorities. Ensure proper grounding of shields, employ compatible shielded accessories, and follow local fire safety regulations for LSOH materials. For long backbone runs, plan conduit and tray routing to minimize bends and mechanical stress; perform post-installation testing to confirm expected performance.
