Gigabit Multi-Mode LC Fiber to Ethernet Media Converter with A SFP SX Module, 1.25G Fiber to Copper RJ45 Media Converter, 1000Base-SX to 10/100/1000Base-TX, MMF, Transmission up to 550 meters/1804 ft

Works, it is the solution I needed

Dip switches can be confusing. But working fine

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.

Power cord was broken and only worked if I held pressure on it. Customer support offered to inspect it if I paid return shipping. I ended up replacing the end of the cord and it works great. Make sure you check everything within the return window

These units burn down easily. I bought 8 pieces lasted for a month got over heated and died. Replaced it with TPLINK expensive but worth every penny.

We have 4 of these installed, working great.

Awesome, worked GREAT!

Works like they say plug in and play over fiber if one has fios why wouldnt you I used a pair of these for a drop to my cisco switch with 80ft fiber patch works flawlessly.

I have never worked with fiber optics, but this device I just plugged and literally played. I am very pleased.

FANTASTIC!!! The sfp module included works on my fortigate sfp port!!! So I have the fortigate on one side and a second of these mediaconverter on the other. Awesome item for the price, couldnt be happier!
