Cisco 4 x SFP10G to QSFP Reverse Adapter Data Sheet

The Cisco^® 4 x SFP10G to QSFP Reverse Adapter (4SQRA) offers Quad Small Form Factor Pluggable Plus (QSFP+) connectivity for 10 Gigabit Ethernet Small Form-Factor Pluggable Plus (SFP+)–only platforms. It allows smooth and cost-effective migration to 40 Gigabit Ethernet by providing an option to use QSFP+ modules with empty SFP+ ports when the other end of the network is running at 40 Gigabit Ethernet.

Features and benefits

The Cisco 4SQRA Reverse Adapter (Figure 1 and Figure 2) converts four SFP+ ports into a QSFP+ port. With this adapter, customers have the flexibility to use a QSFP+ module to connect to a 40 Gigabit Ethernet port on the other end of the link. This flexibility allows a cost-effective transition to 40 Gigabit Ethernet by maximizing the use of existing or new 10 Gigabit Ethernet SFP+ platforms. This reverse adapter supports the QSFP+ optics listed in Table 1.

Mounting accessories

The 4SQRA Reverse Adapter can be attached to a bracket (Figure 3) or mounted on a tray (Figure 4) in groups of eight or less. The 2RU tray features front-facing slots for cable management and a pull-out drawer for easy access. Both the tray and bracket are designed for mounting on a standard 19-inch rack. The bracket includes an outboard extender to alleviate mechanical interference with the rack if necessary.
