NOTE:
The 40G QSFP+ ports of the QSFP-40G-SR4-MM850, QSFP-40G-SR4-MM850-NDDM,
QSFP-40G-CSR4-MM850, QSFP-40G-CSR4-MM850-NDDM, QSFP-40G-IR4-PSM1310 and
QSFP-40G-LR4-PSM1310 fiber transceiver modules can be split into four channels. You can connect a
40G QSFP+ port to four 10G SFP+ ports. The QSFP+ fiber transceiver module and SFP+ fiber transceiver
modules to be connected must be the same in specifications, including central wavelength and fiber type.
