Network cable STEINMARK CAT5E FTP 305 m, CPR Class Dca s2 d2 a1, model DK-F5E-LSZH-Dca

Solid-reel STEINMARK CAT5E FTP network cable, 305 meters long, model DK-F5E-LSZH-Dca, provides CAT5E-performance copper cabling with foil shielding (FTP) to reduce electromagnetic interference and maintain stable data transmission. The cable is intended for horizontal building cabling and structured network installations in offices and commercial premises. Its construction follows the LSZH indication in the model name and complies with CPR Class Dca s2 d2 a1 for reaction-to-fire performance.

Advantages

The FTP shielding around conductor pairs lowers susceptibility to external EMI and crosstalk, improving signal integrity across typical Ethernet links. A 305 m solid reel simplifies long runs and reduces the number of joints in horizontal cabling. Construction using LSZH-compatible materials reduces harmful smoke and corrosive gases in case of fire, while the CPR Class Dca s2 d2 a1 rating provides documented reaction-to-fire characteristics suitable for many indoor building applications.

Suitable for

• Horizontal building cabling for offices and commercial spaces
• Structured cabling backbones and patching to network switches
• Ethernet installations up to CAT5E performance (100 Mbps–1 Gbps depending on network equipment)
• Environments where reduced smoke emission is required

Key specifications

• Category: CAT5E performance (FTP)
• Length: 305 meters on a solid reel
• Shielding: Foil shield (FTP) over twisted pairs
• Conductor type: Solid copper conductors
• Sheath material: Low Smoke Zero Halogen (LSZH) indicated by model name
• Reaction to fire classification: CPR Class Dca s2 d2 a1

How to use

Plan cable routes and measure required lengths allowing service loops and termination at patch panels or keystone jacks. Cut and strip the outer sheath carefully to expose the foil-shielded twisted pairs, keeping the drain wire intact where present for proper grounding of the FTP shield. Terminate onto RJ45 connectors, keystone jacks or patch panels rated for CAT5E following standard T568A or T568B wiring schemes and use appropriate cable management and support to maintain bend radius and avoid mechanical stress. Test final links with a cable tester to verify continuity, pair integrity and performance parameters relevant to CAT5E.

Usage recommendations

Use the cable in indoor horizontal and riser installations where CPR Class Dca and LSZH characteristics are required. Ensure shield termination and grounding at one end or as specified by local grounding practices to maximize EMI protection. Avoid sharp bends and excessive pulling force during installation; follow manufacturer guidelines for minimum bend radius and maximum pulling tension.
