Qsfp28 Port - HPE FlexFabric 5710 Series Installation Manual

Figure 56 QSFP+ fiber cable
IMPORTANT:
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.
NOTE:
• As a best practice, use HPE QSFP+ transceiver modules, QSFP+ cables, or 40G QSFP+ to 4 ×
SFP+ cables for the QSFP+ ports on the switch. The HPE QSFP+ transceiver modules, QSFP+
cables, and 40G QSFP+ to 4 × 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
40G QSFP+ to 4 × SFP+ cables available for the interface cards, contact Hewlett Packard
Enterprise Support or marketing staff.
• For more information about HPE QSFP+ transceiver modules, QSFP+ cables, and 40G QSFP+
to 4 × SFP+ cables, see HPE Transceiver Modules User Guide.

QSFP28 port

The switch provides QSFP28 ports. The QSFP28 ports are 40GE ports by default. To change the
ports to 100GE ports, execute the related command from the CLI. For more information, see
Ethernet interface commands in HPE FlexFabric 5710 Switch Series Command References.
When a QSFP28 port operates as a 40GE port, the QSFP+ modules in
in Table 23, 40G QSFP+ to 4 × SFP+ cables in
available for the QSFP28 port.
A QSFP28 port does not support one-to-four splitting when it operates as a 100GE port. When a
QSFP28 port operates as a 100GE port, the QSFP28 modules in
in Table 27, QSFP+ modules in
in Table 25 are available for the QSFP28 port.
