ENIANHUA 1 Pack Gigabit LC Fiber to Ethernet Media Converter, Mini Ethernet PoE PD SFP Fiber Media Converter, Mini 1x 10/100/1000Base-T RJ45 to 100FX/1000Base-X SFP Slot Converter Transceiver

Bought 4 of these things and they are working and nice and cheap too.

Bought four of these transceivers two months ago. They get quite warm to the touch but appeared to be solid construction. Had one of them fail this week - instead of gigabit it only works at 100mb now. Swapped the cables and fiber module for this one with another one and the issue is in the black metal enclosure itself and not the module inside it. Unfortunately can no longer trust these since long term reliability is in doubt. Not being a name brand there is no company to contact so simply out of the money. Buyer beware.

These work great. I ran some LC to LC line with Ethernet cords at the end of my 330’ fiber run I had no experience in setting these up before but am glad I did. I don’t have to worry about lightning frying Ethernet cord outside or my electronics

I've been working with TCP/IP professionally, and ethernet non-professionally for 25+ years - but have had no direct contact with fiber. I have some runs I want to set up at home - long outdoor runs, without remote power - I don't want to have to worry about moisture, lighting following it home, etc. I started with MMF - even reviewed some media converters on here that I tried out - and it worked fine for the first run. To be honest, I kinda jumped in without doing all of the requisite research - I've since learned that single mode is the better fit for my applications, so I got these for a subsequent run. These are a bit more to set up, but nothing terribly complex or challenging. I really like that they can run off of PoE, and that I can power the remote end off of 5VDC. Perfect for a solar/wind powered weather station, or a solar powered driveway sensor, etc.

This is much smaller than other Media converters and can use power over ethernet. I tested it with some common cisco type 1.25G SFP modules as well Ciena and 1.25G BiDi modules from, Mikrotik and Ubiquiti and they all worked without complaint. They could have saved some cost by leaving out the 5V USB Type-A and Type-A to Type-C cable. The media converter worked well all the 1.25G modules I tested. I wish there was a way to get DMM data off the SFP modules but as with all media converter of this type you can't. Still, I've been looking for a small PoE powered media converter for a number of years and this one fits the bill. It's a great toolbag item if you work with fiber.

My garage is 414' cable feet away from my house and the two are connected with a 2" conduit. I have a CAT5e connecting the two, and I've had "internet", but it constantly bounces. I finally got fed up with it and pulled an 8-strand fiber. I bought two different media converter kits and these are -- by far -- my favorite. They're smaller, they only need a single strand, and connection has been rock solid for 24 hours... not a single drop. The best part is they're powered by USB-C. While the kit includes two USB-C bricks, I don't need them. I have UPS' on both sides that have USB-C on the front covers.
