Cavo di rete EFB Elektronik K5528SW.10 RJ-45 Cat8.1 10 m nero

The EFB Elektronik K5528SW.10 RJ-45 Cat8.1 10 m Black is a high-performance network cable designed for demanding Ethernet environments. With Cat8.1 specification and 40GBase-T cabling technology, this 10-metre cable supports data transfer rates up to 40000 Mbit/s and uses RJ-45 connectors at both ends. The cable is fitted with S/FTP (S-STP) shielding to reduce electromagnetic interference and crosstalk, providing a stable physical layer connection for high-speed networks in data centres, server rooms, or advanced office installations.

Advantages

The cable’s Cat8.1 compliance and 40GBase-T capability allow for very high throughput and low latency over short to medium runs. S/FTP shielding improves signal integrity in environments with multiple cable bundles or electronic equipment. Standard RJ-45 connectors ensure broad compatibility with existing network hardware while the 10 m length provides flexible routing options. The black jacket offers a discreet appearance for visible installations.

Suitable for

• 40GBase-T backbone links in data centres and server rooms
• High-speed uplinks and inter-switch connections
• Workstation connections requiring low-latency, high-bandwidth links
• Environments with significant electromagnetic interference where shielded cabling is needed

Key specifications

• Cable length: 10 m
• Connector type: RJ-45 to RJ-45
• Cabling technology: 40GBase-T
• Shielding: S/FTP (S-STP) full shield with individually shielded pairs
• Category: Cat8.1
• Colour: Black
• Maximum data rate: up to 40000 Mbit/s

How to use

Route the cable between network devices ensuring the RJ-45 connectors are inserted fully into compatible ports until they click. Avoid sharp bends, crushing, or kinking of the cable to preserve shielding and internal pair geometry. For best performance keep the run length within the recommended limits for Cat8.1 and separate the cable from high-power electrical lines where practical. Verify link speed and duplex settings on connected devices after installation.

Recommendations

Use this Cat8.1 S/FTP cable for short to medium-length high-bandwidth connections in controlled environments such as server rooms and structured cabling systems. For outdoor use or runs exposed to mechanical stress, choose a cable rated for those conditions. Test connections with appropriate network diagnostic tools to confirm 40GBase-T performance.
