You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver
module to connect one 100G QSFP28 port to four 10G SFP+ ports. The QSFP+
transceiver module and SFP+ transceiver modules to be connected must be the
same in specifications, including central wavelength and fiber type
A QSFP28 port can be split into four 25G interfaces or four 10G interfaces, except in
the following situations:
•
Interface numbered 31 on the S6850-56HF (excluding the LS-6850-56HF-H3)
and S6850-56HF-SAN switches cannot be split into four interfaces
•
The interface numbered 31 on an S9850-32H switch cannot be split by default.
To split this interface, first enable the hardware resource flex mode for the
device by using the
command. For more information about the hardware resource flex mode, see
device management configuration in H3C S6805 & S6825 & S6850 & S9850
Switch Series Fundamentals Configuration Guide. Only F6633 and later
versions support port splitting of the interface numbered 31 on an S9850-32H
switch
•
When the LSWM18CQ or LSWM18CQMSEC interface module is installed in
slot 2 on the S9850-4C switch, interface numbered 7 on the interface module
cannot be split into four interfaces
•
When the LSWM124TG2H interface module is installed in slot 2 on the
S9850-4C switch, the interface numbered 25 on the interface module cannot
be split into four interfaces
A 100G port on the device might fail to come up when a 100G DAC cable is used to
connect the port to an Intel network card, for example, Intel (rainbow) Eth
E810-CQDA. As a best practice, use an AOC cable or transceiver module for
connection to the Intel network card

With a QSFP+ to SFP+ adapter installed in a QSFP28 port, the QSFP28 port
supports SFP+ transceiver modules
•
Before using a QSFP+ to SFP+ adapter, execute the
command on the QSFP28 port where the adapter is to be installed
•
The QSFP+ to SFP+ adapter is available only in R6555 and later versions
