These SFP adapters offer incredible value for money. They free up valuable Ethernet ports for use with network devices instead of using them as uplinks. They cost much less than SFP GBIC and LC-LC fiber cables. While not available in length for applications that span channels within a rack or adjacent racks, they meet the need for low-cost SFP connections between switches in a rack. I used 2 of these to create an aggregate connection between two Ubiquiti UniFis. Switch. I have a 48-port switch that serves as the main switch and an 8-port PoE switch to provide power and Ethernet to multiple UniFi WAPs. I used two of these to form an aggregate 2Gbps uplink to a PoE switch. While link aggregation wasn't strictly necessary, it would be nice if the PoE switch didn't have a 1Gbps bottleneck for multiple 1Gbps devices. Plus, you have a backup in case one of them fails. Although listed as SFP+, they worked in the SFP ports on both switches, operating at 1Gbps each. The main switch is Ubiquiti UniFi US-48 - https://smile.amazon.
