QSFP+ Ports
Four 40GbE Quad Small Form-factor Pluggable (QSFP+) ports are located on the front panel.
These ports accept approved optical QSFP+ transceivers or Direct Attach Cables (DACs).
BLADE QSFP+ 40GBASE-SR4 transceivers interoperate with any 40GBASE-SR4 compliant
device, and support distances up to 100 meters on OM3 fiber. Transceivers are not included with
the G8264 switch unit.
QSFP+ ports allow you to make one 40GbE connection, or four 10GbE connections, using a
breakout cable, as follows:
QSFP+ optical transceiver with MTP-to-4 LC (SFP+) fiber breakout cable.
This option supports only BLADE 10GBASE-SR SFP+ transceivers. The 40GBASE-SR4
specification (802.3ba-2010) indicates a higher optical power level than standard
10GBASE-SR. BLADE SFP+ SR transceivers can handle the higher optical power levels.
QSFP+ to four 10GbE SFP+ breakout DAC.
The SFP+ connectors on BLADE-branded breakout DACs are labelled A, B, C, and D, which
correspond to the first, second, third, and fourth ports in the port range.
The following QSFP+ transceivers and DACs are available from Blade Network Technologies:
