The QSFP connector is a position and transceiver modules

 All cages use press-fit technology for board termination, and can be used in belly-to-belly (double-sided) applications. An XFP-style gasket is also supported to maintain the cage opening behind the bezel. All QSFP cages will accept copper The QSFP+ connector is a 38 position 0.8mm pitch surface mount connector, available in pocket short distances and offer a highly cost-effective way to connect within racks and across adjacent racks. These breakout cables connect to a 40G QSFP+ port of a Cisco switch on one end and to four 10G SFP+ ports of a Cisco switch on the other end. Cisco currently offers passive cables in lengths of 1, 3 and 5 meters, and active cables in lengths of 7 and 10 meters. EMI between both cage-to-bezel and cage-to-module interfaces. Cages are available with options for riding heat sinks (similar to XFP) and lightpipes. Ganged (multi-port) cages are available for additional density gains.
