Wirewin VKW SFTP K7A LSOH3 500SX Cat.7a S/FTP Bulk Network Cable, Yellow, 500m

For structured cabling installers and data centre technicians, the Wirewin VKW SFTP K7A LSOH3 500SX is a 500-metre reel of Category 7a bulk cable built for high-speed backbone and horizontal runs. The yellow LSOH3 jacket makes it easy to identify in cable trays, while the S/FTP shielding—braided screen plus foil on each pair—protects 10 Gigabit Ethernet signals up to 1000 MHz.

Key specifications

• Cable category: Cat.7a (Category 7a)
• Shielding: S/FTP (Screened Foiled Twisted Pair), braided overall screen, aluminium foil per pair
• Jacket material: LSOH3 (Low Smoke Zero Halogen)
• Length: 500 m
• Colour: Yellow
• Conductor: Bare copper, solid, 23 AWG, 4 twisted pairs
• Impedance: 100 Ohm
• Maximum data rate: 10 Gigabit Ethernet (10GBASE-T)
• Maximum bandwidth: 1000 MHz
• Application: Indoor installation cable
• Packaging: Cable reel

Why choose it

The S/FTP construction offers superior alien crosstalk resistance compared to U/FTP or F/UTP, making it suitable for high-density 10GBASE-T deployments. The LSOH3 jacket emits low smoke and no corrosive halogens in a fire, reducing risk in enclosed spaces.

Ideal use cases

• Data centre backbone cabling
• High-performance horizontal runs in office buildings
• 10GBASE-T Ethernet installations
• Projects requiring halogen-free, flame-retardant cabling

Good to know

This is bulk cable supplied on a reel; connectors are not included. It is intended for permanent installation, not patch cord use.
