Dell 407-BBOU (RK0CX) Compatible 10GBASE-SR SFP+ Transceiver

Dell part number 407-BBOU, also referenced as RK0CX, identifies a 10GBASE-SR SFP+ transceiver for Dell Networking switches running OS10 or FTOS. EdgeOptic's compatible replacement matches the original module spec for spec: 850 nm VCSEL transmitter, PIN photodiode receiver, duplex LC/UPC connector, and 6.1 dB minimum optical budget. That budget supports 300 m over OM3 and 400 m over OM4 multimode fiber under IEEE 802.3ae. The chipset handles data rates from 1.25 Gbps (GbE) through 9.95 Gbps (STM-64) to 10.3125 Gbps (10GbE), with the active rate determined by the host port configuration.

DDM/DOM is supported, providing real-time Tx/Rx power, temperature, bias current, and supply voltage readouts through the SFF-8472 management interface. The module operates at 0°C to 70°C and complies with SFF-8431 and SFF-8432 MSA specifications. Dell maintains separate part numbers for different platform generations and procurement channels. The 407-BBOU targets S4048, S6010, Z9264F-ON, and related switches, while the 407-BBVJ (HN12K) was released for a later generation of PowerSwitch models. Both are 10GBASE-SR modules with identical optical parameters, but each carries its own EEPROM coding and platform qualification list.

EdgeOptic programs the correct Dell vendor ID and compliance bytes into the 407-BBOU compatible, so OS10 recognizes the transceiver without warnings or manual overrides. The module is CE/RoHS certified and compliant with the SFP+ MSA per SFF-8432. Verify the correct Dell SKU against the platform's qualified optics list before ordering, since using the wrong generation part number may trigger an unsupported transceiver warning even though the optical performance is identical.
