Dell (Force10) compatible SFP28-25G-SR Description
EdgeOptic's SFP28-25G-SR compatible is a Dell Networking-coded 25GBASE-SR SFP28 transceiver, a direct replacement for the Dell Networking 25GbE SFP28 SR No FEC MMF Duplex LC transceiver (OEM part number SFP28-25G-SR). It ships with Dell-recognized EEPROM, so Dell PowerSwitch OS10 and PowerEdge server NIC drivers identify the module as a native Dell Networking optic.
The module operates at 25GBASE-SR per IEEE 802.3by Clause 112. 850nm VCSEL transmitter, PIN photodiode receiver, LC/UPC duplex connector on a single pair of OM3, OM4 or OM5 multimode fiber. Reach is 100m on OM4 and OM5, 70m on OM3. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, optical budget 5.3 dB. Line rate covers 8.5 to 25.78 Gbps, so the same module supports both 10GBASE-SR and 25GBASE-SR host ports. Power draw is 0.3W maximum. DOM per SFF-8472, operating case temperature 0 to 70 degrees C.
SFP28-25G-SR is the Dell switch-native OPN used within PowerSwitch OS10, and 407-BBXU is the Dell customer-kit catalog code for a 25GBASE-SR No FEC SFP28 module. Both OPNs cover the same 25GBASE-SR specification on 850nm MMF with LC duplex. Whether the two represent identical hardware revisions should be confirmed against Dell's published transceiver cross-reference table before treating them as interchangeable in a strict sparing context. Dell's 25G SR family also includes SFP28-25G-SR-G2 (Gen2 with integrated FEC) and SFP28-25G-SR-NOF; this page covers the base No FEC OPN. On PowerSwitch OS10, 25G ports default to auto-negotiate FEC and require per-port configuration when driving a No FEC module.
Supported Dell platforms for the SFP28-25G-SR: PowerSwitch S5248F-ON (25G/100G leaf), S5232F-ON (25G/100G high-density leaf), S5224F-ON, S5212F-ON and S5296F-ON (25G/100G data-center leaf family), N3200-ON series (25G stackable campus), plus PowerEdge R640, R740, R740XD, R840, R940 and other SFP28-NIC-equipped servers. On PowerSwitch chassis the module populates the native SFP28 cages; on PowerEdge it seats in the NIC adapter slot and is read by the NIC driver. 400G spine chassis that break out to 25G via QSFP-DD cables use a different SFP28 endpoint part, so confirm the chassis connector type before ordering.
DOM registers for transmit power, receive power, laser bias current, module temperature and supply voltage are exposed through PowerSwitch OS10 CLI and standard SFP28 SNMP MIBs. On PowerEdge servers the same DOM data is available through the NIC driver diagnostic commands. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112. Certifications: CE, RoHS, Class 1 FDA, IEC 60825-1.

Frequently Asked Questions
Is the Dell SFP28-25G-SR the same module as the 407-BBXU?
SFP28-25G-SR and 407-BBXU are both Dell Networking 25GBASE-SR No FEC SFP28 modules. SFP28-25G-SR is the switch-native ordering code used inside PowerSwitch OS10 and Dell's switch configuration tools. 407-BBXU is the customer-kit catalog code used when ordering the transceiver as a separate purchase through Dell's options catalog. Both cover the same 25GBASE-SR specification on 850nm MMF with LC duplex and No FEC by default. Whether they represent identical hardware revisions should be confirmed against Dell's published transceiver cross-reference table before treating them as interchangeable in a strict sparing context; for most procurement decisions the pair is treated as a matched set.
Which Dell PowerSwitch models support the SFP28-25G-SR transceiver?
Confirmed compatible PowerSwitch platforms: S5248F-ON, S5232F-ON, S5224F-ON, S5212F-ON, S5296F-ON, and N3200-ON series. PowerEdge servers with SFP28 NICs including R440, R540, R640, R740, R740XD, R840 and R940 series also accept this module. The SFP28-25G-SR is qualified on PowerSwitch OS10 across the S5xxx and N32xx families; specific firmware minimums vary by release so confirm your OS10 image against Dell's current transceiver compatibility list if precision matters.
Does the SFP28-25G-SR require No FEC or can it run RS-FEC on Dell PowerSwitch OS10?
The SFP28-25G-SR is a No FEC module by Dell's base specification. PowerSwitch OS10 defaults to auto-negotiate FEC on 25G SFP28 ports, and for a No FEC optic the per-port FEC mode should be set to off (or compatible-auto) so the link negotiates cleanly. If your deployment requires RS-FEC per IEEE 802.3by Clause 108, Dell markets a separate Gen2 variant (SFP28-25G-SR-G2) with integrated FEC; the SFP28-25G-SR base OPN is not the right part for an RS-FEC-mandatory host.
Can the Dell SFP28-25G-SR reach 100 meters on OM3 fiber?
No, the reach on OM3 fiber is 70m. The 100m specification applies to OM4 and OM5 multimode fiber. If your cabling plant is OM3 and the run is longer than 70m, either re-terminate with OM4 for the full 100m envelope or consider a 25GBASE-LR module on single-mode fiber for longer spans. The module uses one LC/UPC duplex connector and a single pair of multimode fibers, not a parallel-lane ribbon cable.
