    As it looks like the reviews Amazon associates with this device are with similar devices, thought I should chime in on how this particular device works. I plugged in a Cisco rated 10GTek multimode, 550m range SFP transceiver into this, plugged the other identical SFP transceiver into my genuine Cisco SG300 series switch and strung up a 30m pre-made multi-mode fiber rated for outdoor use. The goal of this setup over copper is electrical isolation in case of lightning. It just works. At this it is by far the cheapest solution I have hit so far that just works. I tested performance between my laptop and main computer with iperf and performance was identical between directly plugging in laptop to my Cisco SG300 and through this media converter, near 1Gb/s speeds. With it being so quick, cheap, and easy to do fiber this way, one has to wonder why the fastest ISP I can get in the middle of a major, dense city only provides much crappier, unreliable, fails as soon as the power goes out, and slower service with much more expensive hardware so they can do it over coax and my only other option is antique, slow phone lines. Plus when I moved in they had to string up new lines and of course they chose copper, not fiber, which makes no sense to me. With a cheap single mode SFP transceiver and a cheap media converter they could provide me much faster service with lines running back to their central office where they could have UPSes and backup generators to make the service reliable and sell the service for more money because it would be worth it. At this the stuff wouldnt be going out / getting fried every time there was a lightning storm, which has become increasingly common and intense in recent years where I live. Also FiOS makes no sense to me either when I was in a FiOS neighborhood because they installed this gigantic box (ONT) in my closet that must of cost them a fortune while this cheap little box I am using does the same job except much faster at maybe 1/40th the price. So its like I could provide awesome service that serves the customers every need and do it well with a $25 box or I could do it badly with a $1,000 box. Of course telco logic is do it badly with the super expensive box that falls way short of the mark every time.

    Hooking an old Cisco 2960 into my network and running into problems with optical converters just not syncing up. This one worked immediately.

    I need a lightning break between the cablemodem and my expensive router. Using this and a fiber switch I had lying around. Works fine.

    solved a problem allowing me to convert the ethernet to fiber, go down 3 stories on the outside of a building, and using a 2nd, convert back to ethernet
