Shielded Cat8 (Category 8) Network Patch Cord (9 Meters)

The 9-meter shielded Cat8 network patch cord is a specialized high-performance solution, tailored to deliver ultra-fast data transmission over a moderate length while maintaining robust electromagnetic interference (EMI) protection. The Cat8 standard, compliant with ANSI/TIA-568-C.2, is designed for 25/40 Gigabit Ethernet (25GBASE-T/40GBASE-T) over distances up to 30 meters—well exceeding the 9-meter length here—operating at a maximum frequency of 2 GHz, which is four times higher than Cat7’s 600 MHz. The shielding, typically a thick braided metal layer (tinned copper) or a combination of foil and braided shielding around the four twisted wire pairs, ensures that even over 9 meters, signal integrity remains uncompromised by external EMI.

The structure of this 9-meter shielded Cat8 cord is optimized for both performance and practicality: four twisted wire pairs (with ultra-tight twists to reduce crosstalk, more compact than lower categories), a heavy-duty braided shield (covering 90%+ of the wire bundle to block EMI), a drain wire for grounding, and a durable outer jacket (LSZH or ruggedized PVC to withstand wear during installation and use). The 9-meter length is a strategic choice for scenarios where devices are not in close proximity—such as connecting top-of-rack (ToR) switches to servers in adjacent racks in a data center, or linking high-performance workstations to a central switch in a large enterprise office—without exceeding Cat8’s maximum effective distance.

This cord is ideal for environments requiring high-speed, long-range (relative to short-haul Cat8 use) connectivity with EMI protection, such as medium-sized data centers, enterprise IT departments running high-bandwidth applications (e.g., 4K video editing, large file transfers), and research labs using data-intensive equipment. For instance, a 9-meter shielded Cat8 cord can reliably connect a server in one rack to a ToR switch 9 meters away, supporting 40 Gbps speeds without signal loss, even if routed near power cables or other EMI sources.

Installation considerations include avoiding excessive bending (the thick shield and tight twists make the cord less flexible than shorter Cat8 cords) and ensuring proper grounding of the shield at both ends to prevent ground loops. The 9-meter length also requires careful routing to avoid tangles or strain on connectors. While more expensive than shorter Cat8 cords or lower categories, this 9-meter shielded Cat8 option provides a balance of length, speed, and EMI protection, making it suitable for applications where short cords are insufficient but 30-meter maximum length is unnecessary. Compliance with ANSI/TIA-568-C.2 is essential to ensure compatibility with 25/40 Gbps equipment.
