Sieťový kábel UNITEK C18149AGY03-3M RJ-45 Cat8 3m čierny

The UNITEK C18149AGY03-3M is a 3 m Cat8 networking cable with S/FTP (double-shielded) construction and RJ-45 connectors on both ends. It supports bandwidth up to 2000 MHz and data transfer rates up to 40 Gbps, designed for high-speed wired connections between computers, routers, switches and gaming consoles while maintaining signal integrity and backward compatibility with earlier Cat standards.

Advantages

The cable’s 4 shielded foiled twisted pairs and an overall aluminum foil shield reduce interference and crosstalk, providing a stable, low-latency connection. Shielded RJ-45 connectors further preserve signal quality. The cable also supports Power over Ethernet (PoE), allowing power and data to be delivered over the same cable when connected to compatible equipment.

Suitable for

• High-speed LAN links between PCs, servers and network switches
• Wired connections for gaming consoles such as PS5, PS4, PS3, Xbox One, Xbox 360 and Nintendo Switch
• Connecting modems, routers, ADSL devices and network adapters
• Environments requiring minimal interference and backward compatibility with Cat7/Cat6e/Cat6/Cat5e/Cat5 devices

Key specifications

• Standard: Cat8
• Length: 3 m

• Maximum data rate: up to 40 Gbps (40000 Mbit/s)
• Shielding: S/FTP (4 shielded foiled twisted pairs + overall foil)
• Connectors: RJ-45 to RJ-45, shielded
• Colour: Black
• PoE: supported

How to use

Connect one RJ-45 end to your network device (PC, router, switch or console) and the other end to the corresponding port on the second device. Ensure connectors are fully inserted until they click. For PoE use, verify that the connected switch or injector provides PoE and that the powered device supports PoE. Route the cable to avoid sharp bends and sources of strong electromagnetic interference.

Recommendations

For best performance, keep cable runs within recommended distances for Cat8 deployments, avoid tight bends and secure the cable away from large electrical cables or noisy equipment. Use shielded network ports or properly grounded patch panels when operating in environments with significant interference.
