UGREEN Cat8 Ethernet Cable (30800) 20m Review: 40Gbps High-Speed Network Cable Test
Introduction
In this review, I’ll be putting the UGREEN Cat 8 Ethernet Cable (Model Number: 30800), a 20-meter behemoth promising 40Gbps speeds, through its paces. I’ve been using this cable for several weeks in various setups, from gaming consoles to a high-bandwidth server connection, to get a real-world feel for its performance and durability.
Features
The UGREEN Cat 8 Ethernet Cable boasts several key features that contribute to its high-speed and robust design. The double-shielded, braided construction immediately sets it apart, promising increased durability and reduced interference. The stated 40Gbps speed and 2000MHz bandwidth are impressive claims, which we’ll test in the performance section.
The cable’s compatibility is another strong point. It seamlessly integrates with various devices, including gaming consoles like PS5 and Xbox, PCs, routers, and more. This backward compatibility with older Cat standards is a nice bonus.

Performance
My testing involved several scenarios. First, I used the cable to connect my PS5 directly to my router, resulting in noticeably smoother online gaming experiences. The elimination of lag was significant, especially in fast-paced games. Next, I connected a high-bandwidth NAS device, transferring large files (multiple gigabytes). Transfer speeds consistently reached close to their theoretical maximum. Finally, I ran a speed test using various tools, and the results consistently matched advertised speeds under optimal conditions. While a 20m cable inherently introduces some signal loss, this was minimal and negligible in my testing. The double shielding clearly mitigates interference effectively.
The cable’s durability has also been impressive. Its flexibility and braided design make it easy to manage, routing it around furniture without causing stress to the connectors or cable itself.
Pros & Cons
- Pros: High speed (close to advertised 40Gbps), robust and durable construction, excellent interference rejection, good value for the length, wide compatibility.
- Cons: Slightly thicker than some Cat 6a cables, minor signal loss at 20m is to be expected.
Final Verdict
The UGREEN Cat 8 Ethernet Cable (30800) delivers on its promises. The 40Gbps speed, coupled with its robust construction and effective shielding, makes it a fantastic option for anyone needing a reliable, high-bandwidth connection over a longer distance. While the slightly thicker cable might not be ideal for extremely tight spaces, the performance improvements far outweigh this minor drawback. I highly recommend this cable for gaming, high-bandwidth data transfers, or any situation demanding a reliable, fast Ethernet connection.
