Network Cable Extralink Twisted pair CAT5E SFTP V2 Outdoor 305M Black

The Extralink Twisted pair CAT5E SFTP V2 Outdoor 305M Black cable is a shielded Cat5e network cable designed for outdoor and demanding environments. It contains four twisted pairs of pure 24 AWG copper conductors with 0.97 mm insulated conductor diameter, a polyethylene (PE) outer sheath and combined shielding: aluminium foil plus aluminium-alloy braid. The spool provides 305 meters of cable and the black jacket suits visible or concealed installations.

Advantages

Shielded S/FTP construction reduces both mutual crosstalk and external electromagnetic interference, supporting Fast Ethernet (100 Mb/s) and Gigabit Ethernet (1000 Mb/s) applications. The PE outer jacket offers high mechanical strength, chemical resistance and a gas barrier useful for outdoor exposure. The supplied self-expanding reel facilitates smooth unwinding and reduces the risk of tangling during installation.

Suitable for

• Outdoor network runs in ducts, on building exteriors and in cable trays
• Environments with elevated electromagnetic interference or nearby power lines
• CCTV and surveillance installations where cable must carry multiple video signals and power
• Local area networks requiring Cat5e performance over shielded cabling

When it may not be suitable

This Cat5e cable is intended for applications that require up to Gigabit Ethernet speeds; it does not meet Cat6 or higher category performance for higher bandwidth or future-proofing. If connectors are required, the product is supplied without factory-attached plugs and will need appropriate RJ45 termination or pre-terminated ends.

Key specifications

• Cable category: Cat5e (S/FTP / SFTP)
• Conductor material and size: solid pure copper, 24 AWG
• Structure: 4 twisted pairs
• Insulated conductor diameter: 0.97 mm
• Shielding: aluminium foil + aluminium-alloy braid
• Outer sheath material: polyethylene (PE)
• Length on spool: 305 m
• Colour: black

How to use

Measure and route the cable along the planned path, using the self-expanding reel to unwind without kinks. Terminate each end with appropriate RJ45 connectors or keystone jacks compatible with shielded Cat5e cabling, ensuring the braid and foil are properly terminated to the connector ground for effective shielding. Use suitable outdoor-rated conduits or clips where exposed to weather and avoid tight bends to maintain signal performance.

What to consider before purchase

• Whether Cat5e bandwidth (up to 1 Gbps) meets current and future network requirements
• Need for termination: cable is sold without connectors
• Suitability of PE jacket for the specific outdoor environment and UV exposure
• Required grounding or bonding for shielded cable in your installation

Usage recommendations

For best results, use this Extralink SFTP Cat5e cable in shielded installations and ground the cable shields at a single point per run. Maintain recommended bend radii, avoid running parallel to high-voltage power lines over long distances, and test each terminated link with a network cable tester to verify continuity and performance.
