About the 407-BBOU

The Dell 407-BBOU is a Dell 10GbE SFP+ SR Optical Transceiver (850nm, 300m MMF) designed for optical transmission across multimode fiber infrastructure. Operating over a calibrated optical wavelength with LC or MPO connectors, the 407-BBOU converts electrical data from host network adapters into optical signals for data center interconnects. In Dell's networking portfolio, 407-BBOU provides low-latency optical links for servers and switches.

Compatibility

The 407-BBOU module installs into compatible transceiver cages on Dell PowerEdge network adapters and Dell PowerSwitch enterprise switches including R740, R640, R750, R650. The 407-BBOU operates over standard multimode optical fiber patch cables up to its rated transmission distance. Supported ports auto-negotiate link parameters based on installed 407-BBOU optics.

How to identify a genuine unit

Authentic Dell 407-BBOU transceivers carry a silver label displaying DP/N 0WTRD1, transceiver model codes, and manufacturing serialization. When installed in Dell switches or network interface cards, the 407-BBOU module registers via internal EEPROM with digital optical monitoring (DOM) reporting laser transmit and receive power.

Buying used

When purchasing a pre-owned 407-BBOU, inspect the optical bore for dust, scratches, or ferrule contamination using a fiber inspection scope. Verify that the metal bail latch on the 407-BBOU operates smoothly and locks firmly into host cages. Test in a switch or adapter port to confirm that DOM telemetry on the 407-BBOU reports normal optical power levels.

Works together

How the Dell 407-BBOU connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Storage

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.

Check compatibility with Dell

Before you buy, confirm the exact configuration against the vendor's own lists: firmware levels, operating systems, adapters and optics that Dell has tested with the Dell 407-BBOU.
