As a best practice, use H3C transceiver modules and network cables for the switch.
The H3C transceiver modules and network cables
are subject to change over time. For the most
recent list of H3C transceiver modules and cables, contact H3C Support or marketing staff.

The S6520X-30QC-EI, S6520X-54QC-EI, S6520X-30QC-HI, and S6520X-54QC-HI switches and
the LSWM2QP2P interface module provide QSFP+ ports. You can install QSFP+ transceiver
modules in Table4-9, QSFP+ cables in Table4-10, and QSFP+ to SFP+ cables in Table4-11 in the
QSFP+ ports.
