QSFP+ provides flexible connectivity for 40Gb Ethernet. For 40Gb-to-40Gb connectivity, clients can use QSFP+ Direct Attach Cables up to 7 meters. For 40Gb connectivity over longer distances, use a QSFP+ transceiver and QSFP+ MTP optical cables. To increase the number of available 10Gb ports, use QSFP+ DAC Break Out Cables to split out each 40Gb port and connect up to four 10Gb SFP+ external ports using copper or leverage the eSR4 Transceiver and 40G eSR4 MTP-4xLC OM3 MMF Breakout Cables for distances up to 300 meters. For 40Gb connectivity over longer distances, use a QSFP+ transceiver and QSFP+ MTP optical cables.
