Transceivers seem to work happily in a pair of SFP ports in some Unifi kit, including sending power and other sensor information to the devices.

Crazy cheap, but works great in 2 Cisco 9200 switches!

Well packaged. Compatible with TP link MCL220L

You guys are awesome! Best Investment I've done :) Transceiver worked like a charm, now my Verizon line is back up on my Aruba Switch.

Thank you!

Generic version is perfectly compatible with Zyxel GS1920 series, port settings on auto / duplex and GO!. Easiest fiber setup ever.

A+ would purchase from FS again

I purchased this 1G SFP for my Cisco switch two months ago, and it has been performing exceptionally well.

Surpassing my expectations, I purchased this product for testing and it turned out to be excellent.It starts working as soon as it's powered on, very convenient.Moreover, the packaging is great and every customer is treated with utmost care. Right after the purchase, the brand even contacted me to arrange guidance, which is very thoughtful.

Clear description and fast delivery. The SFP's works correctly on HW devices. Great service form FS.com.
