I ordered them for Cisco Meraki fiber optic switches. There were no problems with these modules. They say you might have trouble contacting Meraki tech support since it's not part of Cisco, but you'll worry about it when the time comes. The price difference between this and the Meraki is worth the headaches I may or may not have. Approximately 60 Cisco Meraki APs have been installed and there are no issues with inter-building fiber connections using these GBICs.
