The Cisco 40GBASE QSFP+ (Quad Small Form-Factor Pluggable Plus) modules offer customers a wide variety of high-density 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core & distribution layers, and service provider transport applications. The Cisco 40GBASE-SR4 QSFP Modules support link lengths of 100 meters & 150 meters, respectively, on laser-optimized OM3 & OM4 multimode fibers. It primarily enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP multifiber connectors. It can also be used in a 4x 10G mode for interoperability with 10GBASE-SR interfaces up to 100 & 150 meters on OM3 & OM4 fibers, respectively. The worry-free 4x 10G mode operation is enabled by the optimization of the transmit & receive optical characteristics of the Cisco QSFP-40G-SR4 to prevent receiver overload or unnecessary triggering of alarm thresholds on the 10GBASE-SR receiver, & at the same time is completely interoperable with all standard 40GBASE-SR4 interfaces. The 4x 10G connectivity is achieved using an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 40GBASE-SR4 module to four 10GBASE-SR optical interfaces. Cisco QSFP-40G-SR4 is optimized to guarantee interoperability with any IEEE 40 GBase-SR4 & 10 G Base-SR (in 4x 10G mode). Features Support for 40GBASE Ethernet Hot-swappable input/output device that plugs into a 40-Gigabit Ethernet QSFP+ Cisco switch port Flexibility of interface choice Interoperable with other IEEE-compliant 40GBASE interfaces available in various form factors Support for "pay-as-you-populate" model Support for the Cisco quality identification (ID) feature which enables a Cisco switch to identify whether the module is certified & tested by Cisco 40GBASE-SR4, 4 lanes, 850 nm MMF Connector
