About the 470-BCJB
The Dell 470-BCJB is a Dell Networking Breakout Cable QSFP28 to 4x SFP28 100GbE to 4x25GbE Passive DAC 2m engineered for high-speed interconnectivity over a 2.0-meter span at 100GbE to 4x 25GbE. Utilizing precision twinaxial copper conductors terminated with fixed connectors, the 470-BCJB provides low-latency physical transport while consuming less than 0.1W of power. In Dell's infrastructure catalog, 470-BCJB connects PowerEdge servers to top-of-rack switches and storage arrays.
Compatibility
The 470-BCJB cable is compatible with Dell PowerEdge servers and PowerSwitch systems including R750, R650, R760, S5248F-ON. The 470-BCJB connects directly into matching 100GbE to 4x 25GbE ports without intermediate transceivers. Operating over 2.0 meters, the 470-BCJB complies with standard SFF specifications and requires appropriate Forward Error Correction settings on host interfaces.
How to identify a genuine unit
Genuine Dell 470-BCJB cable assemblies feature a white printed flag label displaying DP/N 0G9T4V, cable length 2.0M, and Dell Networking branding. Connected switch operating systems such as Dell OS10 read the internal 470-BCJB EEPROM, verifying authentic Dell serialization and cable telemetry.
Buying used
When evaluating a used 470-BCJB cable, inspect the twinaxial outer jacketing for severe kinks, crushed shielding, or conductor strain near the molded connector hoods. Test both metal connector shells on the 470-BCJB to ensure that pull-release latches engage firmly into host cages. Verify that connected 470-BCJB ports establish a stable physical link without packet errors.
