Patchcord LAN Extralink Cat.8.1 S/FTP 1m 40G blue, copper twisted-pair cable (EX.38831)

The Extralink Patchcord LAN Cat.8.1 S/FTP 1m in blue is a shielded copper twisted-pair patch cable engineered for 40G Ethernet over short copper links. Designed for high-density network environments such as data centres and server racks, this 1 metre patch cord combines individual pair foil shielding with an overall braided/foil shield to reduce crosstalk and electromagnetic interference. The cable uses four pure copper pairs and shielded, gold-plated RJ45 connectors to maintain stable high-speed links and support Power over Ethernet (PoE) where applicable.

Advantages

Cat.8.1 S/FTP construction delivers higher transmission speeds and a greater operating frequency range compared with lower-category copper cables, resulting in improved throughput for demanding applications. The combination of per-pair foil and an overall shield provides robust protection against EMI and crosstalk, increasing link reliability in congested or industrial environments. Gold-plated, shielded connectors ensure durable contact and reduced insertion loss, while the pure copper conductors support consistent signal integrity and PoE delivery.

Suitable for

• 40G short-link backbone connections in data centres and server rooms
• High-density patch panels and switch-to-switch links
• Environments with significant electromagnetic interference
• PoE-enabled network devices where copper power delivery is required

Key specifications

• Category: Cat.8.1 S/FTP (shielded foil per pair + overall braided/foil shield)
• Rated throughput: up to 40 Gb/s for supported applications
• Length: 1 metre
• Conductor: four twisted pairs of pure copper
• Connector type: shielded RJ45 with gold-plated contacts
• Color: blue

How to use

Insert the shielded RJ45 connectors into compatible shielded ports on switches, patch panels or network devices, ensuring the connector latches fully engage. Route the cable without tight bends and avoid running parallel and close to high-voltage power lines to preserve shielding effectiveness. For PoE applications, confirm device compatibility and power budgets before use. For optimal performance in high-speed links, use appropriate Cat.8.1-compliant ports and equipment and keep link lengths within recommended copper limits.

Recommendations

Use this 1 m Cat.8.1 patchcord for short, high-speed interconnects where maximum copper performance and shielding are required. Store and install the cable in environments within standard temperature and humidity ranges, avoid excessive bending radii, and pair with shielded network hardware to maintain full EMI protection and signal integrity.
