Interface Specifications for Data Plane Connections for the QFabric System
QFX3000 QFabric system data plane connections use QSFP+ transceivers. The QSFP+
transceivers are installed in QFX3500 Node devices and 16-port QSFP+ front cards on
the QFX3008-I Interconnect device. This topic describes the interface specifications for
those transceivers.
NOTE: Use only transceivers and connectors purchased from Juniper
Networks for your QFX Series device.
