IMPORTANT:
The QSFP-40G-SR4-MM850 and QSFP-40G-CSR4-MM850 transceiver modules can be used to
connect one 40G QSFP+ port to four 10G SFP+ ports. The QSFP+ transceiver modules and SFP+
transceiver modules to be connected must be the same in specifications, including central
wavelength and fiber diameter.
NOTE:
•
As a best practice, use H3C QSFP+ transceiver modules and cables for the QSFP+ ports on the
S6520-42QF-EI and S6520-52QF-EI switches.
•
The H3C QSFP+ transceiver modules and cables are subject to change over time. For the most
recent list of H3C QSFP+ transceiver modules and cables, contact your H3C sales
representative or technical support engineer.
For specifications of H3C QSFP+ transceiver modules and cables, see
