Goobay networking cable Black 0.25 m Cat8.1 S/FTP

Goobay networking cable Black 0.25 m Cat8.1 S/FTP is a short high-performance patch cord with copper conductors and a low-smoke, halogen-free (LSZH) outer sheath. Assembled on both ends with RJ45 (8P8C) connectors featuring 50 µm gold-plated contacts and latch protection, the 0.25 m cable supports modern multi-gigabit Ethernet standards and is intended for use in GHMT-certified CAT 8.1 channels when paired with the specified certified components.

Advantages

The CAT 8.1 S/FTP construction provides an overall shield with aluminium foil around each twisted pair (PiMF) and an additional aluminium braid for the cable jacket, reducing crosstalk and external interference. With a transmission bandwidth up to 2000 MHz and support for 25GBase-T and 40GBase-T, the cable offers significantly higher bandwidth than CAT 6A while remaining backwards compatible with 10BASE-T, 100BASE-TX and 1000BASE-T. The LSZH sheath limits smoke and hazardous gases in case of fire, and gold-plated contacts ensure reliable electrical contact and corrosion resistance.

Suitable for

• Short patch connections in GHMT-certified CAT 8.1 channels
• 25GBase-T and 40GBase-T multi-gigabit Ethernet links
• Power over Ethernet applications (PoE, PoE+, UPoE, 4PPoE)
• HDBaseT signal transmission

How to use

Connect one RJ45 connector to the network port of a switch, router or patch panel and the other connector to the device to be linked (PC, server, transceiver or other Ethernet-enabled equipment). Ensure the cable is used within the tested channel configuration and that GHMT-certified components listed for CAT 8.1 installations are applied for guaranteed channel performance. Avoid sharp bends and excessive pulling force when routing the cable to maintain shielding and achieve expected transmission characteristics.

Recommendations

Use this 0.25 m Cat8.1 patch cord for short, high-speed connections inside data centers or network racks where GHMT-certified CAT 8.1 channel components are installed; store and install in dry indoor environments and do not expose the LSZH sheath to open flames or prolonged UV exposure.
