GoodConnections Alcasa 8080-030Y Cat8.1 S/FTP Network Cable, 3 m, Yellow

With a blistering 40 Gbps data rate and 2000 MHz bandwidth, this Cat8.1 cable moves massive files in seconds and keeps latency at rock-bottom levels. The 3-metre yellow jacket stands out in any rack, while S/FTP shielding and gold-plated RJ45 connectors guarantee a rock-solid link for 25G/40G Ethernet, data centres, and high-end home networks.

Overview

The GoodConnections Alcasa 8080-030Y is a premium Cat8.1 network cable built for the most demanding copper Ethernet applications. Its S/FTP (S-STP) construction wraps each of the four twisted pairs in an individual foil shield, with an overall braided screen on top — effectively eliminating alien crosstalk and electromagnetic interference. Pure copper conductors and gold-plated RJ45 plugs ensure maximum conductivity and long-term corrosion resistance, while the flexible PVC jacket makes installation easy even in tight spaces.

What stands out

• Cat8.1 performance: up to 40 Gbps and 2000 MHz — ideal for 25GBASE-T and 40GBASE-T.
• Double shielding (S/FTP) for flawless signal integrity near power lines or dense patch panels.
• Backward compatible with Cat5e, Cat6, Cat6a, and Cat7 equipment, so it works with existing gear.
• PoE support up to 100 W — power access points, cameras, and phones over the same run.
• Gold-plated RJ45 connectors resist wear and deliver a reliable connection for years.
