Cisco offers a broad range of 40 Gigabit Ethernet interfaces to meet the high-performance connectivity requirements of campus, data center, and cloud deployments. Our latest innovation, the QSFP BiDi 40 GE transceiver, helps you migrate from 10 to 40 Gigabit Ethernet on the same fiber infrastructure, saving you money.
Broad 40 Gigabit Ethernet Connectivity Options
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.
CFP 40 Gigabit Ethernet Transceiver Modules
See the variety of choices available with the Cisco 40GBASE and OTU-3 C Form-Factor Pluggable (CFP) modules. These devices enable connectivity in the distribution and core layers of data center, enterprise, and service provider networks.
