The Cisco QSFP to SFP or SFP+ Adapter (QSA) Module offers 10 Gigabit Ethernet and 1 Gigabit Ethernet connectivity for Quad Small Form-Factor Pluggable (QSFP)-only platforms. It allows smooth and cost-effective migration to 40 Gigabit Ethernet by providing an option to use lower-speed Small Form-Factor Pluggable (SFP) or Enhanced Small Form-Factor Pluggable (SFP+) modules in empty QSFP ports or when the other end of the network is running at lower speeds.

Features and Benefits

The Cisco QSA Module (Figure 1 and Figure 2) converts a QSFP port into an SFP or SFP+ port. With this adapter, customers have the flexibility to use any SFP+ or SFP 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 40 Gigabit Ethernet by maximizing the use of high-density 40 Gigabit Ethernet QSFP platforms. This adapter supports all SFP+ optics and cable reaches and several 1 Gigabit Ethernet SFP modules (Table 1).

Compatible Switch Models and SFP or SFP+ Modules

The list of switch models supporting the Cisco QSA Module is available in the 40 Gigabit Ethernet compatibility matrix at: http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_24900.html.

A list of Cisco SFP or SFP+ transceiver modules that can be plugged into the QSA module is provided in Table 1.
