## Summary description

GOOBAY 55143 is a 20 m networking cable compliant with Cat8.1 standard, featuring S/FTP (S-STP) shielding for improved crosstalk and EMI protection. Both ends have RJ-45 connectors with gold-plated contacts, suitable for high-speed Ethernet links, data centers, server racks, switches and broadband home networks requiring robust shielded cabling.

## Long description

GOOBAY 55143 is a 20 m Cat8.1 S/FTP (S-STP) networking cable in grey, designed for high-speed Ethernet connections in data centers, server rooms and advanced home networks. The cable supports transmission performance up to 2 GHz (2000 MHz) and is suitable for 25G/40GBASE-T applications while remaining backward compatible with lower Ethernet categories. Both ends are fitted with shielded RJ-45 male connectors with gold-plated contact surfaces to ensure reliable contact and reduced signal loss.
Advantages
The double-shielded S/FTP design combines individual pair metal foil shielding with an overall braided shield to minimize crosstalk and electromagnetic interference. Gold-plated contacts on the RJ-45 plugs provide corrosion resistance and stable conductivity. The cable’s construction includes a slimline anti-kink sleeve with a length indication to improve handling and routing in racks and tight spaces. Cat8.1 performance and the updated RJ-45 plug standard make the cable suitable for high-bandwidth, low-latency links.
Suitable for
 25G/40GBASE-T connections in data centers and server racks
 High-speed uplinks between switches and routers
 Professional workstations requiring robust shielded cabling
 Broadband home networks that need future-proof, shielded Ethernet
 Environments with elevated electromagnetic interference where shielded cables are recommended
Key specifications
 Category: Cat8.1
 Shielding: S/FTP (pair in metal foil + overall braided shield)
 Frequency bandwidth: up to 2000 MHz (2 GHz)
 Length: 20 m
 Connectors: RJ-45 male to RJ-45 male, shielded plugs
 Contact finish: gold-plated contacts (50 µ on contact surfaces as per industry plug standard)
 Color: grey
 Suitable for 25/40GBASE-T applications and backward compatible with lower categories
How to use
Connect one RJ-45 plug to the Ethernet port of a switch, router or network interface and the other plug to the corresponding port on the connected device. Ensure the cable is routed without sharp bends and avoid tight loops or kinks; use the slimline anti-kink sleeve and length marking to guide installation. For shielded performance, verify that connected devices or patch panels provide proper grounding for the cable shield. Do not exceed the recommended channel or patching distance for the intended Ethernet link when integrating with other cabling.
Usage recommendations
Use this Cat8.1 S/FTP cable for short, high-speed links such as switch-to-switch uplinks and server connections where 25G/40G performance is required. Maintain proper grounding of shielded connectors and avoid running the cable in close parallel to strong power lines to preserve signal integrity.
