QSA Adapter – 100G QSFP28 to 25G SFP28 Converter Module, for Cisco CVR-QSFP28-SFP28 Mellanox, Dell, Juniper, Arista, Extreme and More.

The 10Gtek QSFP28 to SFP28 Adapter (QSA) Module offers 25 Gigabit Ethernet connectivity for Quad Small Form-Factor Pluggable (QSFP28)-only platforms. It allows smooth and cost-effective migration to 100 Gigabit Ethernet by providing an option to use lower-speed Enhanced Small Form-Factor Pluggable (SFP28) modules in empty QSFP28 ports or when the other end of the network is running at lower speeds. The QSA Module interoperates with all major optical modules and direct attached copper cable vendors. Its design assures minimum loss on the conversion path between the QSFP28 cage and the SFP28 receptacle. The high-speed data channel of the SFP28 receptacle is connected to lane 1 of the QSFP28 connector. The three remaining channels on the QSFP28 connector are not connected. With this adapter, you have the flexibility to use any SFP28 module or cable to connect to a lower-speed port on the other end of the network. This flexibility allows a cost-effective transition to 100 Gigabit Ethernet by maximizing the use of high-density 100 Gigabit Ethernet QSFP28 platforms. This adapter supports all SFP28 optics and cable reaches. Compatible Switch Models and SFP28 Modules.
