Features and Capabilities

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 BiDi Monitor

The Cisco QSFP BiDi Monitor provides passive optical tap capability for Bidi links, allowing data monitoring for security and network optimization analysis.

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.
