## Summary description

GOOBAY 66729 is a 25 m networking cable meeting Cat8.1 standard with S/FTP (S‑STP) shielding for reduced interference. Both ends have gold‑plated RJ‑45 connectors suitable for high‑speed Ethernet links and data centers, supporting short‑reach 25G/40G applications and shielded installations requiring enhanced crosstalk and EMI protection.

## Long description

GOOBAY 66729 Cat8.1 S/FTP (S‑STP) Black 25 m is a high-performance networking cable designed for short‑reach 25G/40G Ethernet links and shielded installations. The cable conforms to the Cat8.1 specification and offers transmission performance up to 2 GHz, with S/FTP shielding (each twisted pair wrapped in foil plus an overall braided shield) to reduce crosstalk and electromagnetic interference. Both ends feature gold‑plated RJ‑45 male connectors with latch protection and a slim anti‑kink sleeve showing the length for convenient handling and installation.
Advantages
The cable provides enhanced signal integrity for high-speed LAN and data center applications thanks to its PIMF pair shielding and overall mesh braid, making it suitable for environments with elevated EMI. Gold‑plated contacts ensure reliable electrical connection and corrosion resistance, while the shielded RJ‑45 plugs with latch protection improve connector durability and prevent accidental disconnection. The 25 m length balances reach and manageability for rack-to-rack or equipment-to-patch-panel cabling.
Suitable for
Short‑reach 25G/40GBASE‑T Ethernet links in data centers and server rooms
Shielded LAN installations where EMI and crosstalk reduction are required
High‑speed desktop to switch connections and patch panel to switch cabling
Environments requiring backward compatibility with lower Cat standards
Key specifications
Category: Cat 8.1
Shielding: S/FTP (pair in metal foil + overall braided shield)
Bandwidth / transmission performance: up to 2000 MHz (2 GHz)
Length: 25 m
Connectors: RJ‑45 male to RJ‑45 male, shielded plugs with latch protection
Contact plating: 50 µin (approx.) gold‑plated contact surfaces
Color: Black
How to use
Install the cable by inserting each RJ‑45 plug into the corresponding shielded Ethernet port on network switches, patch panels or devices until the latch clicks into place. Ensure the connected ports and equipment support shielded Ethernet and that chassis grounding is present where required to maintain the effectiveness of the S/FTP shielding. Route the cable avoiding sharp bends and sources of strong electromagnetic interference; the anti‑kink sleeve helps preserve bend radius near the connector.
Usage recommendations
For optimal performance, use GOOBAY Cat8.1 S/FTP cable in shielded installations with proper grounding and within the recommended short‑reach distances for 25G/40GBASE‑T. Avoid excessive pulling force and tight bends; secure the cable with appropriate cable management to prevent strain on the RJ‑45 connectors.
