100G to 25G Adapter

Ascent’s 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 converts a QSFP28 port into an SFP28 port. With this adapter, customers 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.
