NOTE:
•
As a best practice, use H3C QSFP+ transceiver modules, QSFP+ cables, or QSFP+ to SFP+
cables for the QSFP+ ports on the switch. The H3C QSFP+ transceiver modules, QSFP+ cables,
and QSFP+ to SFP+ cables available for the QSFP+ ports are subject to change over time. For
the most recent list of QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to SFP+ cables
available for the QSFP+ ports, 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 SFP+
cables, see
