IMPORTANT:
• A QSFP-100G-SR4-MM850 transceiver module supports one-to-four splitting. You can use it to
connect a 100G QSFP28 port to four 25G SFP28 ports. The QSFP28 transceiver module and
SFP28 transceiver modules to be connected must be the same in specifications, including
central wavelength and fiber type.
• QSFP28 ports do not support QSFP+ to SFP+ cables and cannot be split to 10GE ports by using
QSFP+ transceiver modules.
• The S6520X-30HF-EI, S6520X-54HF-EI, S6520X-30HF-HI, and S6520X-54HF-HI switches do
not support the QSFP-100G-D-CAB-5M transceiver modules.
NOTE:
• 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.
• For the specifications of H3C transceiver modules and network cables, see H3C Transceiver
Modules User Guide.
