QSFP+ 40GBase-LR4 support
The Brocade ICX 7750 supports 40GBASE-LR4 QSFP+ LC optics (up to 10 km over SMF) in the port ranges shown in Table 4.
The Brocade ICX 7750 also supports 40GBASE-SR-BD bi-directional (BiDi) QSFP+ transceivers with duplex LC optics. The 40 GbE
BiDi optics support two 20 GbE channels over duplex fiber cable, with the transmit and receive of each channel operating at two
wavelengths on a single fiber.
The 40 GbE BiDi transceivers enable 40 GbE links to be supported on installed 10 GbE duplex fiber infrastructure. This optic has the
same port limitations as the LR4 optic..

The Brocade ICX 7750 ports available for breakout are shown for each model in Table 5.
QSFP+ to SFP+ adapter support
The Brocade ICX 7750 supports a third-party QSFP+ to SFP+ adapter for cost-effective connections between 40 GbE QSFP+ ports and
10 GbE hardware using standard SFP+ optical cabling rather than breakout cables.
An SFP+ transceiver (SR, LR, or USR) inserted in the QSFP+ to SFP+ adapter behaves as if it is connected to the first of the 4 breakout
ports on the 40 GbE QSFP+ interface with no other ports available in the breakout. The 4x10 GbE breakout mode must be configured on
the QSFP+ interface.
