49NOTE:• As a best practice, use H3C SFP transceiver modules, SFP+ transceiver modules, or SFP+cables for the SFP+ ports on the switch. The H3C SFP and SFP+ transceiver modules andcables are subject to change over time. For the most up-to-date list of SFP transceiver modulesand cables, contact your H3C sales representative or technical support engineer.• The S5820V2-48S, S5820V2-52QF (LS-S5820V2-52QF-H3), S5820V2-52QF(LS-S5820V2-52QF-H5), and 5820V2-54QS-GE switches do not support theSFP-XG-LX220-MM1310 transceiver module.For more information about specifications for the SFP transceiver modules, SFP+ transceivermodules, and SFP+ cables, see H3C Transceiver Modules User Guide.QSFP+ portThe S5820V2-52QF, S5820V2-52QF-U, S5820V2-52Q, and S5820V2-54QS-GE switches provideQSFP+ ports. You can install QSFP+ transceiver modules in Table 15, QSFP+ DAC cables in Table16, and QSFP+ AOC cables in Table 18 in the QSFP+ ports as needed.Table 15 QSFP+ transceiver modules available for the QSFP+ portsQSFP+transceivermoduleCentralwavelength(nm)ConnectorFiber typeanddiameter(μm)Modalbandwidth(MHz × km)Max transmissiondistanceQSFP-40G-SR4-MM850 850 MPO Multi-mode,50/1252000 100 m (328.08 ft)4700 150 m (492.12 ft)QSFP-40G-CSR4-MM850 850 MPO Multi-mode,50/1252000 300 m (984.25 ft)4700 400 m (1312.33 ft)QSFP-40G-LR4-WDM1300Four lanes:• 1271.• 1291.• 1311.• 1331.LC Single-mode,9/125 N/A 10 km (6.21 miles)QSFP-40G-LR4L-WDM1300Four lanes:• 1271.• 1291.• 1311.• 1331.LC Single-mode,9/125 N/A 2 km (1.24 miles)Table 16 QSFP+ DAC cables available for the QSFP+ portsQSFP+ DAC cable Description Max transmissiondistanceLSWM1QSTK0 40G QSFP+ QSFP+ 1m Direct Attach Copper Cable 1 m (3.28 ft)LSWM1QSTK1 40G QSFP+ QSFP+ 3m Direct Attach Copper Cable 3 m (9.84 ft)LSWM1QSTK2 QSFP+ QSFP+ 5m Direct Attach Copper Cable 5 m (16.40 ft)
