DeLOCK RJ45 Network Cable Cat.8.1 S/FTP 25 cm 40 Gbps Black

The DeLOCK RJ45 Network Cable Cat.8.1 S/FTP 25 cm is a short, high-performance patch cable designed for 40GBASE-T Ethernet. It supports data transfer rates of up to 40 Gbps at a frequency of 2 GHz and features S/FTP shielding to minimise electromagnetic interference, while RJ-45 connectors on both ends provide standardised connectivity for network devices.

Advantages

This Cat.8.1 cable offers certified GHMT performance for reliable 40 Gbps transmission over short distances. Its S/FTP construction reduces crosstalk and external interference, and the compact 25 cm length is convenient for connections inside racks, between switches and servers, or for tidy cable routing in high-density setups.

Suitable for

• High-speed server-to-switch connections in data centres
• Short patch connections in network racks and cabinets
• 40GBASE-T test and measurement setups

Key specifications

• Cabling technology: 40GBase-T
• Maximum data rate: 40 Gbps
• Frequency: 2 GHz
• Length: 0.25 m (25 cm)
• Connectors: RJ-45 to RJ-45
• Shielding: S/FTP
• Colour: Black

How to use

Connect one RJ-45 connector to your network device (for example, a switch or server) and the other RJ-45 connector to the corresponding port on the opposite device. Ensure connectors are fully inserted until the latch clicks. Use the 25 cm length for short-distance patching to maintain signal integrity and reduce excess cable slack.

Recommendations

For optimal performance at 40 Gbps, use this Cat.8.1 S/FTP cable for short connections within racks or between adjacent devices. Avoid sharp bends and excessive mechanical stress on the connectors. Verify compatible 40GBASE-T ports and GHMT certification requirements in your network environment before deployment.
