NOTE:
•
As a best practice, use H3C QSFP+ transceiver modules, QSFP+ cables, or QSFP+ to 4 x SFP+ cables for
the QSFP+ ports on the switch. The H3C QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to 4 x
SFP+ cables available for the interface cards are subject to change over time. For the most recent list of
QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to 4 x SFP+ cables available for the interface
cards, contact H3C Support or marketing staff.
•
You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to connect a
QSFP+ port to four 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.
For more information about H3C QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to 4 x SFP+
cables, see
