QSFP+ ports allow you to make one 40 GbE connection, or four 10 GbE

connections using a breakout cable, as follows:

•

QSFP+ optical transceiver with MTP-to-4 LC (SFP+) fiber breakout cable. This

option supports only Lenovo 10GBASE-SR SFP+ transceivers. The

40GBASE-SR4 specification (802.3ba-2010) indicates a higher optical power

level than standard 10GBASE-SR. Lenovo SFP+ SR transceivers can handle the

higher optical power levels. This cable must be purchased separately.

•

QSFP+ to four 10 GbE SFP+ breakout DAC. The SFP+ connectors on supported

breakout DACs are labelled A, B, C, and D, which correspond to the first,

second, third, and fourth ports in the port range. This cable must be purchased

separately.
