Verkkokaapeli DeLOCK 80556 RJ-45 Cat8.1 0,25 m harmaa

The DeLOCK 80556 networking cable is a Cat8.1 patch cable with a length of 0.25 m and RJ-45 connectors on both ends. It supports data transfer rates up to 40 Gbps (40000 Mbit/s) and is designed for 40GBASE-T Ethernet applications with a frequency of up to 2 GHz. The cable features S/FTP shielding and comes in grey.

Advantages

The S/FTP shielding reduces electromagnetic interference and crosstalk, helping to maintain stable high-speed connections. Cat8.1 specification and RJ-45 connectors enable compatibility with standard Ethernet ports while supporting up to 40 Gbps transfer rates. The short 0.25 m length is suitable for direct device-to-device connections in dense setups and reduces signal attenuation.

Suitable for

• 40GBASE-T Ethernet links
• High-speed switches and servers in data centres
• Direct connections between network devices in rack or desktop environments
• Situations requiring minimal interference and short patching runs

Key specifications

• Standard: Cat8.1
• Maximum data rate: 40 Gbps (40000 Mbit/s)
• Frequency: up to 2 GHz
• Length: 0.25 m
• Connectors: RJ-45 to RJ-45
• Shielding: S/FTP
• Colour: Grey

How to use

Connect one RJ-45 connector to an Ethernet port on a compatible switch, server or network device and the other connector to the corresponding port on the second device. Ensure both devices support the intended link speed (40GBASE-T) and that ports and cables are properly seated. Use the cable for short patching runs where a 0.25 m length is sufficient.

Recommendations

For optimal performance, use this Cat8.1 cable for short, high-speed connections inside racks or between closely spaced devices. Avoid excessive bending and keep the cable away from strong sources of electromagnetic interference despite its S/FTP shielding.
