Product Info

Currently available on Japan for approximately ¥2,924 (tax included) for the 4-pack. Buffalo provides a standard one-year warranty. The package contains only the cables; no additional accessories are included. Positioned in the mid-range market, this cable offers a balance between performance and affordability. It outperforms entry-level Cat5e cables while remaining more budget-friendly than shielded Cat6a professional cables. The unbreakable tab is its standout feature.

Best Use Cases

Users who frequently connect/disconnect modems or ONUs: The unbreakable tab prevents connector damage over repeated use. Ideal for renters or those who move equipment often. Not necessary if your setup is permanent. Office or retail environments with frequent cable re-routing: The easy-grip connector makes insertion and removal smooth, even in tight spaces. The 10m length provides ample slack for rack-to-desk runs. Gamers or remote workers needing reliable wired connectivity: Cat6a support ensures future-proofing for 10Gbps networks. However, achieving 10Gbps requires compatible switches and NICs. Not ideal for: Short cable runs (e.g., desk to wall) where 10m is excessive. Also not suitable for high-EMI environments that require shielded cables.
