Sieťový kábel EFB Elektronik K5518.25 RJ-45 Cat6 25 m biely

The EFB Elektronik K5518.25 is a 25 m white Cat6 networking cable with RJ-45 connectors and S/FTP shielding. It supports 1 Gigabit Ethernet and is manufactured to Cat.6 and TIA/EIA 568B coding standards. The cable construction includes 4 pairs of AWG27/7 conductors with PiMF (paired in metal foil) shielding and a total diameter of approximately 6.2 mm, providing reliable high-speed data transmission and reduced electromagnetic interference. The outer sheath is LSZH (low smoke zero halogen) and the cable meets flame retardant and low-smoke/halogen-free standards.

Advantages

The shielded S/FTP design and paired-in-metal-foil construction minimize crosstalk and external interference, enabling stable 1 Gbps connections over the 25 m length. RJ-45 connectors are IEC 60603-7-5 compliant and the moulded strain relief with latch protection improves connector durability and reduces the risk of accidental disconnects. The LSZH jacket and compliance with IEC 60332-1, IEC 60754-2 and IEC 61034 ensure reduced smoke and no halogen emissions in case of fire.

Suitable for (tasks / use cases)

• Wired Ethernet connections in offices and homes
• Connecting network switches, routers and PCs
• Structured cabling installations requiring Cat6 performance
• Environments where low smoke and halogen-free materials are required

How to use

Plug each RJ-45 connector into the corresponding Ethernet ports of your devices (router, switch, PC). Ensure connectors click into place and that the moulded strain relief and latch protection are not obstructed. For structured cabling, follow TIA/EIA 568B wiring scheme when terminating or testing connections. Avoid tight bends and protect the cable from sharp edges to preserve signal integrity.

Recommendations

For best performance, keep cable runs within recommended maximum lengths for Ethernet segments, avoid running the cable parallel to power lines for long distances, and use appropriate cable management to prevent kinks or excessive bending.
