The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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.
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.

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.
