407-BBYC Dell 40GbE QSFP+ BiDi Transceiver 850/900nm LC Duplex MMF 100m OM3 / 150m OM4

407-BBYC Dell 40GbE QSFP+ BiDi Transceiver 850/900nm LC Duplex MMF 100m OM3 / 150m OM4

Dell-branded SFP / SFP+ / SFP28 / QSFP+ / QSFP28 transceiver — fiber or DAC copper optic for Dell server NICs and switches.

Specifications

• Part Number: 407-BBYC
• Brand: Dell
• Form Factor: QSFP+ (Quad Small Form-factor Pluggable Plus) plug-in module
• Optic Class: 40GBASE-SR-BiDi bi-directional QSFP+ optical transceiver, hot-pluggable, with DDM/DOM digital diagnostics
• Speed: 40 Gb/s (40 Gigabit Ethernet)
• Wavelength: 850nm (SR/MMF) / 1310nm (LR/SMF) / 1550nm (ER/SMF) / coded by class
• Connector: LC duplex (most) / MPO (parallel-fiber QSFP) / RJ45 (BASE-T variants 1G)

Compatibility

Dell transceivers are firmware-keyed — third-party SFPs may work but typically trigger 'unsupported transceiver' warnings. For production use, deploy vendor-original.

• Dell 40G/100G server NICs (Mellanox ConnectX, Marvell): R640/R740/R750/R760 with QSFP+/QSFP28 ports
• Dell EMC PowerSwitch (S-series): S5232/S5248/S5296/Z9264 spine + ToR 100G fabrics

Use Cases

Server NIC ports + ToR switch uplinks + SAN HBA ports. SR/MMF for in-rack and short-rack connections (cheaper). LR/SMF for cross-datacenter / cross-MDF runs. DAC copper for in-rack direct attach (lowest latency, lowest cost, no transceiver pair needed). AOC for medium-range (5-30m) where DAC max length insufficient.
