10Gtek 2-Pair of 1.25G SFP Bidi Transceiver, 1000Base-BIDI SingleMode Simplex LC Fiber Module for Cisco 1000BASE-BX3-U/1000BASE-BX3-D, Ubiquiti UniFi UF-SM-1G-S, SMF 1550nm/1310nm, DDM, up to 2km

Works flawless, used two sets and both work fine, excellent choice

Works in my Ubiquiti UniFi switches fine and the fast delivery helps with getting a network Up and running faster. I will buy again and have. Great price for what they are and the metal tin they come in is some creative packaging that also does a great job of protecting sensitive electronics. I’ll reuse the tin’s for small screws or such. BiDi type SM fiber connections are the way to go. Single fiber is cleaner and no more troubleshooting if the A and B are swapped.

El adaptador me llegó Europeo, y yo lo necesitaba EEUU , estoy inconforme con esto ya que no había una opción para seleccionar el tipo de enchufe

You need to use LC/UPC connectors with this and pretty much all transceivers. This may be obvious to you if you work with fiber but the descriptions don’t tell you that and you can easily buy LC/APC connectors by accident and they will fit but won’t work. I have used fiber in the past to connect switches but this was my first project that I ran bare fiber and used mechanical SC/APC connectors. When I ordered jumpers to connect the devices, I ordered them with both sides green which was SC/APC to LC/APC. After troubleshooting the terrible performance, I was told that I needed SC/APC to LC/UPC jumpers. Hopefully this helps someone else avoid the mistake and it would be useful if 10gtek could add that to the description. Great product as always. I have used 10gtek in various Meraki, Cisco, Ubiquiti, and Dahua devices and they have always worked great. (Except when I used the wrong connector)

Awesome, great for a single strand. Check out the youtube videos on how these work. Very cool! We doubled our bandwidth by switching these out for the old 2 strand fiber GBIC's Never had one of these fail yet. Going on 4 years

Had an issue with the "yellow" transceiver and contacted the company, I quickly had a new set in mt hands and all worked out just great. (I think it was just a bad unit or even a connector.) I have used 10Gtek before without issues and will continue to look to them in the future.

These SFPs work well in my Ubiquiti US-48-750W and US-24-250W switches as well as a TP-Link MC220L media converterI am currently using 2 sets of these on a 2 strand fiber run in link aggregation. The bi-directional signaling over a single fiber pair has enabled me to double the bandwidth for this application which is much cheaper than running a second fiber run.TP-Link media converter: https://www.amazon.com/dp/B003CFATL0

Works awesome with Ubiquiti. The only thing I would like to see different is being able to monitor light levels within the UI.
