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

If you need media converters I would recommend buying these. They work perfectly and are plug and play right out of the box. You must have over on each end of your fiber.

Devices worked out of the box with no setup required.

I am very happy with this solution. Plug and play no issues, I used this to provide internet connectivity to a detached building approx 100 ft away from router location. Ran conduit, pulled per-terminated fiber through conduit, powered up units then connected to fiber, router with attached NAS and remote desktop. Tested with file transfer from NAS to remote desktop and received over 600Mbps on file transfers speed. I have tried the Ethernet over power solution and best I received was 40Mbps.

Works perfectly

it is what it says it is

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.

Worked great. I used it with a fairly short fiber cable (about 100).

Works as advertised

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

We have a digital billboard outside the TV station I work for. Weve had issues in the past with lightning getting into the building (from the digital billboard or the 350ft tower outside). Unfortunately the computer went out for the digital billboard and when the repair man from the company that supplies/supports the digital billboard replaced the computer... he unintentionally broke the fiber line... like completely ripped one of the fiber lines from the connector. I ran cat5 to the billboard as a temporary patch to keep it up, as it generates roughly $1000-1500 in ad revenue every day. I had issues initially but had to tweak some settings on the cradle point modem/router to get it working. Once I was able to get the fiber line re-terminated I connected our TP-Link boxes (fiber to cat5 converter) but they wouldnt connect. I could unplug the cat5 cable from the cradle point modem/router and plug it into my laptop and it would connect over the fiber line without any issues... it just wouldnt communicate when connected to the cradle point modem/router. I checked the very few settings on the TP-Link boxes but got nothing. I believe a firmware update on the cradle point modem/router is what killed it (made it no longer work with the TP-Link fiber converters). I ordered a couple of these Gigabit fiber to cat5 converters on a hunch and they worked immediately.... no fuss or config changes needed. They just worked... After 6 weeks of back and forth between getting the computer replaced, running a temp cat5 line and getting the fiber re-terminated I was finally able to put this issue to bed. Shipping was very fast which is why I decided to order from my personal account w/prime (as anything I order through Amazon through procurement at work takes weeks). Got these in a couple days and got reimbursed for the out of pocket expenses. They just worked!!! and thats all that matters....
