Specifications:
The 10Gtek QSFP to SFP Adapter (QSA) Module offers 10 Gigabit Ethernet connectivity for QSFP-only platforms.It allows smooth and cost-effective migration to 40 Gigabit Ethernet by providing an option to use lower-speed SFP modules in empty QSFP 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 QSFP cage and the SFP receptacle. The high-speed data channel of the SFP receptacle is connected to lane 1 of the QSFP connector. The three remaining channels on the QSFP connector are not connected. With this adapter, you have the flexibility to use any 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. Compatible Switch Models and SFP Modules.
