Network interface
| Characteristic | Description |
|---|---|
| IEEE standards |
IEEE 802.3 40 Gbit/s Ethernet IEEE 802.3 10 Gbit/s Ethernet |
| Type of physical interface | QSFP+ |
| Number of physical interfaces | 2 ports |
| Supported pluggable modules |
QSFP+ Note: QSFP+ 40GBASE-PSM4 can break out to 4 SFP+ 10GBASE-LR.
Note: QSFP+ 40GBASE-SR4 can break out to 4 SFP+ 10GBASE-SR.
Note: QSFP+ 40GBASE-CR4 can break out to 4 SFP+ 10GBASE-CR.
Note: QSFP+ 40GBASE-LR4 pluggables cannot be used with breakout cables, as they
interface to single-mode fibers where the four 10 Gbit/s lanes are multiplexed
and therefore do not allow mechanical breakout.
