540-BDDX Dell Intel E810-CQDA2 Dual Port 100GBE QSFP28 PCIe Low Profile Adapter

540-BDDX Dell Intel E810-CQDA2 Dual Port 100GBE QSFP28 PCIe Low Profile Adapter

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

Specifications

• Part Number: 540-BDDX
• Brand: Dell
• Form Factor: SFP (1G) / SFP+ (10G) / SFP28 (25G) / QSFP+ (40G) / QSFP28 (100G) / QSFP-DD (200G/400G) — see PN
• Optic Class: SFP / SFP+
• Speed: 10G 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 server NICs (Intel/Broadcom/Mellanox/QLogic): R630/R730/R640/R740/R750/R760 + all PowerEdge with SFP cage
• Dell EMC PowerSwitch (S-series / N-series): S4128/S4148/S5232/N3024 1G+10G + 25G+ ToR
• Dell EMC SAN (PowerStore / ME4 / SC): FC + iSCSI ports

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.
