### ⭐⭐⭐⭐⭐ 







  
  
    Works out of the box with Ubuntu
  

*by S***W on Reviewed in the United States on 7 November 2022*

I'm using on a laptop running Ubuntu Linux (20.04).  I just plugged it into my USB Port and it appeared as eth1 without any extra driver installation.  Seems to be working perfectly

### ⭐⭐⭐⭐⭐ 







  
  
    Fantastic piece of equipment - Fiber to USB
  

*by D***Y on Reviewed in the United States on 18 November 2018*

A few of years ago, I would have happily parted with my left leg to have one of these!And finally, here it is. Throw in your Gigabit SFP, plug it into your USB, and off you go!Being able to use different (MSA Compliant) SFP's is wonderful, fewer parts to carry around - I just add one of these, and ALL my SFP's can be USB connected.The case is well made, very robust, however, a lack of cover on the SFP port is irritating. DuckTape to the rescue! And that is the only flaw I can find in this productThe speed? Amazing! What you would expect from Fiber. The speed was constant over long runs, and over long files, not just bursts.The unit is sturdy.

### ⭐⭐⭐ 







  
  
    Unfortunately impractical for it's main appeal
  

*by D***N on Reviewed in the United States on 25 September 2019*

Let me start by saying I am a huge fan of StarTech and their products, both in my professional uses and personal uses.This product does what it says it does. It works, yes. However, the main appeal to a fiber optic connection is the crazy fast speeds. I'm sure it's capable of those speeds until it reaches the USB-A 3.0 connection to the PC/Mac and is hit with a bottleneck of slow transfer time. This product would be much more practical in USB-C 3.1 and would be a perfect fit for Thunderbolt 3 to SFP. Hopefully a product with high fiber rated speeds on both sides of the dongle is released by StarTech soon. I have confidence that it will be, they are an industry leader in innovation.
