Patchcord LAN Extralink Cat.8.1 S/FTP 2 m 40G blue, copper twisted-pair (EX.38848)

Extralink Cat.8.1 S/FTP patchcord, 2 m, blue, is a shielded copper twisted-pair Ethernet cable designed for short-range, high-bandwidth LAN links. Supporting data rates up to 40 Gb/s and operating at higher frequencies than lower-category cables, this patchcord is suited for dense network environments such as data centres, server racks and high-performance network equipment. The S/FTP construction — an overall braided shield combined with individually foil-shielded pairs — reduces crosstalk and electromagnetic interference to maintain stable, high-speed connections.

Advantages

The cable’s four pure copper twisted pairs and shielded RJ45 connectors with gold plating provide reliable signal transmission and low contact resistance. S/FTP shielding delivers enhanced protection against EMI and near-end crosstalk, increasing connection stability in congested installations. Compared with lower category cables, Cat.8.1 delivers higher throughput, greater operating frequency range and improved immunity to external interference, making it a future-oriented choice for evolving network requirements.

Suitable for

• Short-range 40G Ethernet connections in data centres and server rooms
• High-density patch panels and server rack interconnects
• Connections between 40G-capable switches, routers and network devices
• Environments requiring strong EMI protection such as industrial sites and broadcast facilities

Key specifications

• Category: Cat.8.1 S/FTP (overall braid + individually foil-shielded pairs)
• Length: 2 m
• Conductor: Four twisted pairs, pure copper
• Maximum supported data rate: up to 40 Gb/s
• Connector type: Shielded RJ45 with gold-plated contacts
• Colour: Blue
• Suitable for Power over Ethernet (PoE) applications

How to use

Insert the shielded RJ45 connector into the shielded Ethernet port of your switch, server or network device until the latch clicks. Ensure that both ends are properly seated and that any metal shielding on equipment chassis is connected to maintain grounding continuity. Use the patchcord for short horizontal or rack-to-rack connections where 40G performance is required; avoid bending the cable sharply near the connector to preserve shielding integrity and conductor performance.

Recommendations

For optimal performance, use this Cat.8.1 S/FTP patchcord in shielded installation environments and connect to devices with compatible shielded ports. Maintain recommended bend radius and avoid running the cable in parallel with high-power electrical conduits; for long permanent links, consider structured cabling solutions rated for the installation distance rather than patchcords.
