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.

Works well as needed. Issue was with shipping FS didn't provide US Customs invoice so shipping was delayed untill I sent a reminder. Wish they had Canadian presence, overall happy with the product.

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

Todo bien pero me cobro la paquetería impuestos que no lo habían echo antes

Well packaged. Compatible with TP link MCL220L
