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

Easy to install, plug and play

I hooked them up and once they linked up instant connection

Worked great, one unit quit after year and a half. Bought another along with Amazon extended warranty

ran 100M of fiber for lightning isolation, bought these to connect them. Laziness really, because i have sfp cages on both sides. These worked with the fiber which i basically tried to screw up the install, for months. I recently took the SFP transceivers out and put them in two different branded switches, and it works fine. I will be buying more SFP transceivers to replace these so i can experiment with running fiber. Basically, if you want a cheap way to test fiber runs, that you can use for a long time, i think these are a good buy.

would recommend.

Dip switches can be confusing. But working fine

This does exactly as expected. I have had them running for almost a year now and had no issues.

I live in a rural area where I receive internet access via an antenna on a 50-foot tower. The receiver on the tower is wired with a 150-foot ethernet cable that plugs into a network controller. Although the tower cable has a surge suppressor, a lightning strike fried it and came down the ethernet cable to damage the rather expensive controller. After much troubleshooting and repair, I decided that even a short fiber optic cable link between the tower and my equipment might prevent a recurrence. These relatively inexpensive converters accept the ethernet cable input/output and convert it to light pulses for transmission between the two converters. The fiber optic could be any length, but it can interrupt the electric surge.

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.

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