Juniper QFX-QSFP-DAC-3M InfiniBand/fibre optic cable QSFP+

The QSFP+ DAC cables consist of a cable assembly terminated with QSFP+ transceivers on either end. If you use the QSFP+ DAC cable as the data plane connection between a QFX3600-I Interconnect device and a QFX3600 or QFX3500 Node device, the interface is automatically configured to operate at 40 Gbps. If you use the QSFP+ DAC cable to interconnect a QFX3600 Node device with another device, the interface is automatically configured to operate as four 10-Gigabit Ethernet interfaces over one cable.
