Features and Capabilities

4 x SFP10G to QSFP+ Reverse Adapter for 40G Connectivity to SFP+ Ports

The Cisco 4 x SFP10G to QSFP+ Reverse Adapter (4SQRA) offers QSFP+ connectivity for 10 Gigabit Ethernet 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.

Quad Small Form-Factor Pluggable (QSFP) Bi-Directional (BiDi) Transceiver Helps Accelerate 40 GE Adoption

The Cisco QSFP BiDi transceiver offers the industry's most cost-effective solution for 40-Gbps connectivity. By transmitting full-duplex 40 Gigabit Ethernet over a duplex multimode fiber (MMF), it helps enable seamless 10 to 40 Gigabit Ethernet migration over your 10 Gigabit Ethernet fiber infrastructure.

QSFP+ Options for High-Density 40 GE Connectivity

With the development of the SFF-8436 Multi Source Agreement, Cisco now offers a variety of IEEE- and MSA-compliant Quad Small Form-Factor Pluggable Plus (QSFP+) devices for copper and fiber networks. The Cisco 40GBASE QSFP+ devices help enable connectivity between server access, top-of-rack, and end-of-row switches deployed in high-performance computing networks.
