New Options for 40 Gigabit Ethernet Connectivity
To address higher port-density and bandwidth requirements in data center, enterprise, and service provider networks, the IEEE committee officially standardized 40 Gigabit Ethernet in July 2010 under IEEE 802.3ba. Cisco offers a range of 40 Gigabit Ethernet interfaces that meet connectivity requirements for high-performance computing, cloud services, and aggregation layers.

Quad Small Form-Factor Pluggable (QSFP) Bi-Directional (BiDi) Transceiver Helps Accelerate 40 GE Adoption
The new Cisco QSFP BiDi transceiver currently offers the industry's most cost-effective solution for 40-Gigabit connectivity. By transmitting full-duplex 40 Gigabit Ethernet over one duplex multi-mode fiber (MMF), it can enable seamless 10 to 40 GE migration over your 10 GE fiber infrastructure.
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.
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.
