INFRALAN Cat.7A 1250 AWG22 S/FTP 4P CPR Dca 25Gbit/s ready network cable, rapeseed yellow RAL1021, 100m

INFRALAN Cat.7A 1250 AWG22 S/FTP 4P CPR Dca 25Gbit/s ready network cable in rapeseed yellow (RAL1021) is a shielded, four-pair cable designed for high-performance structured cabling. Its S/FTP construction (overall braid plus individually foil-shielded pairs) and AWG22 conductor size support stable high-frequency transmission, making it suitable for demanding Ethernet links, backbone runs and server room installations. The cable is supplied on a 100 m reel and carries a CPR Dca fire classification for use in commercial and industrial environments where defined reaction-to-fire performance is required.

Advantages

The S/FTP shielding reduces crosstalk and external electromagnetic interference, improving signal integrity for high-speed applications up to 25 Gbit/s readiness. AWG22 conductors offer lower attenuation and improved power handling compared with smaller gauge conductors, supporting longer link distances within structured cabling limits. The bright rapeseed yellow (RAL1021) sheath provides clear visual identification for cable management in racks and cable trays. The CPR Dca rating supplies documented fire performance suitable for many professional installation contexts.

Suitable for

• High-speed Ethernet links up to 25 Gbit/s readiness in LAN and data centre environments
• Backbone and horizontal structured cabling runs in offices and technical rooms
• Server rack and switch interconnects where shielded cable is required
• Installations requiring distinctive coloured cabling for identification and troubleshooting

When it may not be suitable

This Cat.7A S/FTP cable is optimized for environments that require robust shielding and higher conductor cross-section. It may be unnecessary for basic residential networks or low-speed applications where unshielded Cat5e/Cat6 cables would be more cost-effective. The cable’s stiffness due to AWG22 conductors and shielding can make tight bends and very compact duct installations more difficult compared with thinner, unshielded alternatives.

Key specifications

• Category: Category 7A (Cat.7A)
• Conductor: 4 pairs, solid AWG22
• Shielding: S/FTP (overall braided shield + foil shield per pair)
• Data rate readiness: up to 25 Gbit/s
• Fire classification: CPR Dca
• Length: 100 m on reel
• Sheath colour: Rapeseed yellow (RAL1021)

How to use

Install the cable following standard structured cabling practices: route cables in cable trays or ducts, avoid running parallel to power lines to minimise interference, and maintain manufacturer-recommended bend radius to preserve cable performance. Terminate the cable with compatible shielded connectors and ensure proper grounding of the overall braid and connector shields to maintain the effectiveness of the S/FTP construction. Use patch panels and labelled cable management to keep identification clear, taking advantage of the rapeseed yellow sheath for visual tracing.

What to consider before purchase

• Verify that network hardware and patch panels support shielded cabling and proper grounding
• Confirm required data rates and link lengths to ensure Cat.7A and AWG22 characteristics meet performance needs
• Check installation space and bend radius constraints due to the cable’s stiffness
• Ensure the rapeseed yellow colour fits site identification and cabling standards

Usage recommendations

For best results, pair this INFRALAN Cat.7A S/FTP cable with shielded connectors and properly earthed panels, maintain recommended bend radius during installation, and plan routing to minimise exposure to strong electromagnetic sources. Regularly label and document runs to make use of the cable’s distinct colour for efficient maintenance and troubleshooting.
