QSFP+ provides flexible connectivity for 40Gb Ethernet. For 40Gb-to-40Gb connectivity, clients can use QSFP+ Direct Attach Cables up to 3 meters. To increase the number of available 10Gb ports, use QSFP+ DAC Break Out Cables to spit out each 40Gb port and connect up to four 10Gb SFP+ external ports using copper. For 40Gb connectivity over longer distances, use a QSFP+ transceiver and QSFP+ MTP optical cables to connect up to 4 10Gb ports using fiber. 10Gb transceivers are needed at the other end.
