Patchcord Extralink Cat.8.1 S/FTP 0.5 m 40G blue — copper twisted-pair cable (EX.38824)

The Extralink Cat.8.1 S/FTP patchcord in blue is a 0.5 m copper twisted-pair cable engineered for short-range high-speed network links. Terminated with shielded RJ45 connectors, this patchcord supports Ethernet transmission up to 40 Gb/s and is designed for installations where high frequency performance and reduced interference are required, such as server racks, network cabinets and interconnects inside data centers.

Advantages

The S/FTP construction provides individual pair shielding plus an overall braid shield to minimize electromagnetic interference and crosstalk, improving signal integrity at higher frequencies. The use of pure copper conductors and shielded, gold-plated connectors ensures stable electrical contact and compatibility with Power over Ethernet (PoE) devices. Compared with lower-category cables, this Cat.8.1 patchcord offers higher throughput, better immunity to external noise and greater long-term suitability for evolving network demands.

Suitable for

• Short-range 40G Ethernet interconnects in data centers and server rooms
• Patching between switches, routers and high-performance network equipment in racks
• Environments with elevated electromagnetic interference where shielding is required
• Connections that require PoE power delivery over copper pairs

Key specifications

• Cable category: Cat.8.1 S/FTP
• Length: 0.5 m
• Conductor material: pure copper, four twisted pairs
• Shielding: individual pair foil shields plus overall braided shield (S/FTP)
• Connector type: shielded RJ45 with gold-plated contacts
• Maximum supported Ethernet speed: up to 40 Gb/s
• Colour: blue

How to use

Connect the shielded RJ45 connectors to the corresponding ports of network devices such as switches, routers or servers, ensuring that mating shielded ports or chassis grounding are used when available to maintain the effectiveness of the cable shielding. Use the 0.5 m length for short patch runs inside racks or between adjacent devices. Verify port configurations and link speed settings on your equipment to enable up to 40 Gb/s operation where supported.

Recommendations

For optimal performance, route the patchcord away from large sources of electrical noise and avoid sharp bends or kinks; maintain the manufacturer’s recommended minimum bend radius. When deploying in shielded environments, ensure proper grounding of connectors and patch panels. Use this cable for short, high-speed links rather than long horizontal runs to match Cat.8.1 intended applications.
