Assuming you have ordered the correct plug for your switch? It’s just a case of plug the module into the SFP port and connect the fibre patch lead and the modules work straight away.I have been using these modules for a few weeks now and there had been no problems. They seem well made and robust.

I needed this for working around Ubiquiti's incompetence. Turns out that their UDM Pro, despite having "pro" in its name, sometimes it behaves like a toy networking wise as the developers haven't really finished writing the firmware and the tech support is too simple to understand a detailed bug report, including how to reproduce a bug.The problem with two internet connections with one media converter and one modem is that it needs two RJ45 cables that need plugging into one router. But, Ubiquiti in their infinite wisdom, implemented only one RJ45 WAN and two SFP+ ports that may serve as WAN/LAN. So, lacking enough inputs, I've configured one of the ports in the switch as WAN2 (port 8. A feature that's supported, yet broken in unfunny ways, so much so that I suspected that my main ISP is doing something dodgy until I saw the same behaviour for my backup connection.Cue this adapter to enable WAN2 on port 10 or 11 on UDM Pro. Problem worked around.TL:DR it does what it says on the tin. Runs at the expected gigabit. Runs a bit hot, but so far it has not caused any trouble. It actually comes in a metal storage case which is quite a nice touch. Works with SFP or SFP+ ports.

Purchased for use with a US-8-150W and US-24-250W with multimode OM4 and they work brilliantly. Connection came straight up. Nice protective casing for shipping and storage as well.

Cheaper than OEM, even though they may not last as long. You can afford to change these out every couple of years if they start reporting errors.Used with a media converter as the job required it. No issues at all.Also used them on Cisco switches and they worked fine.

Use this in my ubiquiti switch. Absolutely fine, no issues no packet drops no overheating. All seems well for the price of it.

Great product .

I've bought quite a few 10Gtek SFP modules over the years and have had great success with all of them. Generally when I'm in the market for new SFP modules I tend to look at 10Gtek's offerings first.This was a 4 pack of the gigabit 1000Base-SX modules which I have used to link a Cisco SG350-10 to a Mikrotik CRS308-1G-8S+IN with 2 ports on each device using 802.3ad LACP and they work perfectly in both devices.I've been using these modules for nearly a year with no issues at all. The same can also be said for the 10Gtek 10Gbase-SR 10 Gigabit SFP+ modules I'm also using several of.10Gtek tends to be much cheaper than the main manufacturers offerings, i.e. Cisco, but also seem to perform just as well and are highly compatible with most devices.

Does the trick and is half the price of the Meraki branded alternatives
