For example, you can install SFP-GE-LH100-SM1550 transceivermodules in ports 1 and 2, other types of transceiver modules in ports 3 and 4, andSFP-GE-LH100-SM1550 transceiver modules in ports 5 and 6.NOTE:• As a best practice, use H3C transceiver modules and cables for the switch.• The H3C transceiver modules and cables are subject to change over time. For the most recentlist of H3C transceiver modules and cables, contact your H3C Support or marketing staff.• For more information about H3C transceiver modules and cables, see H3C Transceiver ModulesUser Guide.SFP+ portThe switch provides four fixed SFP+ ports on the front panel. To connect peer SFP+ ports over a longdistance, use SFP/SFP+ transceiver modules and fibers. To connect peer SFP+ ports over a shortdistance, use SFP/SFP+ cables. You can install the GE SFP transceiver module and cables in Table25, 10-GE SFP+ transceiver modules in Table 26, and 10-GE SFP+ cables in Table 27 in the SFP+ports.
