Patch cord GOOBAY CAT 8.1 S/FTP (PiMF) black 0.25 m RJ-45–RJ-45

GOOBAY CAT 8.1 S/FTP patch cord, 0.25 m, in black, is a short high-performance Ethernet connection cable with twin RJ-45 plugs and gold-plated contacts. Built with 99.9% oxygen-free copper (OFC) AWG 24 conductors and a halogen-free (LSZH) sheath, the cable provides strong shielding (S/FTP with pair-in-metal-foil) to minimise crosstalk and electromagnetic interference. Designed for high-frequency data links and data centre patching, this Cat 8.1 patch cord supports high bandwidths and reliable contact performance for short interconnects between patch panels, switches and devices.

Advantages

The cable combines robust mechanical design with high electrical performance: gold-plated RJ-45 contacts reduce corrosion and improve continuity, while the S/FTP construction (foil for each pair plus overall braid) offers superior protection against EMI compared with unshielded or partially shielded cables. With a bandwidth rating up to 2000 MHz and construction optimised for Cat8.1, the patch cord supports multi-gigabit and 25/40GBASE-T Ethernet links where short, highly shielded connections are required. The LSZH outer sheath reduces halogen emission in case of fire, suitable for installations with higher fire-safety requirements.

Suitable for

• Connecting patch panels to switches in data centres and server rooms
• Short horizontal or rack patching between network equipment and distribution frames
• High-bandwidth links for multi-gigabit Ethernet, 25G/40GBASE-T testing and deployments
• Applications requiring strong shielding to minimise EMI, such as dense rack environments

Key specifications

• Cable category: Cat 8.1, S/FTP (pair in metal foil + braid)
• Length: 0.25 m
• Conductor: 99.9% oxygen-free copper (OFC), AWG 24
• Bandwidth: up to 2000 MHz (2 GHz)
• Connectors: RJ-45 to RJ-45, straight plugs with gold-plated contacts (50 µ) and locking lever
• Sheath: halogen-free (LSZH), black
• Supports: 25/40GBASE-T and downward compatible with 10/100/1000 Mbps Ethernet
• PoE capable (supports Power over Ethernet standards)

How to use

Insert the RJ-45 plug into the compatible RJ-45 jack on the network device, switch or patch panel until the locking lever clicks to ensure a reliable mechanical connection. Use this 0.25 m patch cord for short interconnects within racks or between adjacent devices where minimal cable length and maximum shielding are required. Avoid sharp bends near the connector and maintain recommended bend radius to preserve signal integrity. For installations that require multiple shielded connections, ensure connectors and ports are properly grounded to benefit from the S/FTP shielding.

Usage recommendations

Use this patch cord for short, high-frequency links inside racks or between patch panels and switches. For full Cat8.1 system performance, pair shielded cables with shielded RJ-45 ports and maintain proper grounding. Avoid using excessive cable length for Cat8 applications; this 0.25 m cable is intended for close-proximity patching and rack use.
