ipolex A Pair of Bidi Gigabit Single-Mode LC Fiber to Ethernet Media Converter, with BiDi SFP LX Module, 1310nm/1550nm, SMF, up to 20-KM, 1.25G Fiber Media Converter,1000Base-LX to 10/100/1000Base-TX

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 wouldn't 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 it's 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.

This is a great product, very easy to setup and works like a charm

Works better than expected

Works perfectly

I hooked them up with the fiber I purchased and it seemed to work well.Note: I have only hooked it up to test it

This was plug and play with no issues. Just a straight forward solution at the right price.

Bought a pair of these converters and a 30-meter fiber cable to replace an aerial, copper Ethernet cable between two buildings. The fiber setup worked great for a day and then crapped out. Since cable and converters were new, I had to determine which part was bad. After buying a short fiber patch cable, I determined the problem was in one of the converters. I got a replacement set and it has been working great for the last month. Since something in the original pair of converters was bad, I give 4 rather than 5 stars.Installation was simple, even though I've never worked with fiber before. The setup is pretty obvious. Plug in the fiber cable to the converters on each end, plug in your RJ45 Ethernet network cable to the converters on each end, and plug in the power supplies for the converters. Done. The one thing you have to be sure of (when ordering) is to make sure the fiber cable matches the converters. These converters expect a duplex, single-mode fiber cable with LC connectors on the ends. The description of the cable I got was: "100 Feet (30 Meters) Uniboot LC to LC Outdoor Armored Fiber Patch Cable, Low Friction Single Mode Duplex Fiber Optic Cable Jumper Optical Patch Cord, 9/125um, (OS1/OS2 Compatible), LSZH Black" This cable came configured as a crossover cable, so the TX from one converter goes into the RX of the other -- and vice versa.

It worked when tested. good deal.
