S/FTP Cat7 Network Cable electro base STX 305m LSZH CPR Class Cca

electro base S/FTP Cat7 Network Cable STX on a 305 m reel is a shielded structured-cable solution designed for high-performance Ethernet and data centre links. The construction combines individually foil-shielded twisted pairs (S/FTP) with an overall braided shield to minimise crosstalk and external electromagnetic interference. The cable jacket is LSZH (low smoke zero halogen) and meets CPR Class Cca fire performance, making it suitable for installations where reduced smoke and low toxicity are required. The product supports high-speed data transmission across copper-based networks and complies with CE and RoHS standards.

Advantages

The S/FTP Cat7 design provides enhanced protection against alien crosstalk and electromagnetic disturbances compared with unshielded alternatives, improving signal integrity for 10 Gigabit Ethernet and other high-bandwidth applications. The LSZH jacket reduces the release of toxic and corrosive gases in the event of a fire, while the CPR Class Cca rating documents controlled flame spread and heat release characteristics for safer use in buildings. The 305 m reel format simplifies cable management and long runs without frequent joins.

Suitable for

• High-speed Ethernet networks up to 10 Gbps and beyond in balanced copper infrastructures
• Data centre horizontal and backbone cabling
• Commercial and office floor installations where LSZH and CPR Cca are required
• Environments with significant electromagnetic interference such as near electrical equipment or power lines
• Structured cabling projects requiring long continuous cable runs

Key specifications

• Cable category: S/FTP Cat7 (individually foil-shielded twisted pairs with overall braid)
• Length per reel: 305 meters
• Jacket material: LSZH (low smoke zero halogen)
• Fire performance: CPR Class Cca
• Conductor type: stranded or solid copper cores suitable for balanced Ethernet (category cable standard)
• Shielding: pair-level foil plus overall braided shield for improved EMC protection

How to use

Prepare the cable for termination by carefully removing the outer LSZH jacket without damaging the overall braid. Fold back the braid and remove pair foils as needed to expose the twisted pairs, keeping pair twist integrity as much as possible. Terminate onto appropriate Cat7-compatible keystone jacks, shielded plugs, or patch panels that support S/FTP constructions and grounding. Ensure the overall shield and any drain wire are properly connected to the equipment or grounding point to preserve shielding effectiveness. When routing, avoid tight bends and maintain the manufacturer’s minimum bend radius; secure runs in cable trays or conduits as required by local installation rules.

Usage recommendations

For best results, use shielded connectors and grounded patch panels dedicated to shielded cabling systems. Test installed links with a certified cable tester to verify performance parameters such as propagation delay, insertion loss and NEXT/PSNEXT. Store the reel in a dry, dust-free environment and avoid exposure to direct sunlight or temperatures outside the specified handling range. Follow local electrical and building codes when installing in plenum or riser spaces.
