GoodConnections Alcasa 8080L-200 cabo de rede Cat8.1 S/FTP, 20 m, cinzento, RJ45, 40 Gbit/s, 2000 MHz

In a busy data center, a network engineer replaces an aging Cat6a patch cord with the GoodConnections Alcasa 8080L-200. The 20-meter grey cable snakes neatly between a top-of-rack switch and a high-throughput server, locking into place with gold-plated RJ45 connectors. Instantly, the link negotiates at 40 Gbit/s, and latency-sensitive applications respond without a hitch.

Key specifications

• Length: 20 m
• Category: Cat8.1 (Category 8.1)
• Shielding: S/FTP (S-STP) – screened and foiled twisted pairs
• Connectors: RJ45 male to RJ45 male, gold-plated contacts
• Data transfer rate: up to 40 Gbit/s
• Bandwidth: up to 2000 MHz
• Conductor material: copper
• Colour: grey
• Compliance: TIA/EIA-568-C.2-1, ISO/IEC 11801

Why choose it

This patch cable delivers headroom for the most demanding Ethernet environments. The S/FTP construction combines an overall braided screen with individual foil shielding on each pair, effectively blocking alien crosstalk and electromagnetic interference. Gold-plated contacts resist corrosion and maintain signal integrity over thousands of mating cycles. With a 2000 MHz bandwidth, it comfortably supports 25GBASE-T and 40GBASE-T links up to 30 meters, making it a future-proof investment for high-speed networking.

Ideal use cases

• Data centers and server rooms requiring 25/40 Gigabit Ethernet
• High-performance workstation connections for video editing or 3D rendering
• Backbone links between switches and patch panels in enterprise networks
• Power over Ethernet (PoE) applications up to the cable's rating

Good to know

The cable is built with solid copper conductors for superior conductivity and long-term reliability. Its grey jacket is easy to identify in crowded racks and blends with standard cable management. While Cat8.1 is backward compatible with lower categories, its full 40 Gbit/s capability is realized with compatible Cat8.1 equipment. The 20-meter length offers flexibility for runs between adjacent racks or across a server room without excess slack.
