What customers say
This optical USB hub earns high praise specifically for its exceptional reliability in extending USB 2.0 signals over long fiber optic distances. Professional users value its ability to maintain signal integrity where standard copper fails, making it essential for installations needing electrical isolation. Reviewers consistently note its robust, durable build quality and dependable performance once set up. The main drawback cited is the significant investment required. For users whose needs do not strictly demand extreme distance or optical isolation, the high cost diminishes the overall value proposition. While it excels in its specialized niche, some desire future versions supporting faster USB standards.
