Dell SFP28-25G-SR Compatible 25GBASE-SR SFP28 for Dell PowerSwitch S5x00F-ON

EdgeOptic's Dell SFP28-25G-SR compatible is a Dell-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor SFP28 dual-rate 10G/25G SR transceiver. Dell SFP28-25G-SR is Dell's ordering code for the 25GbE SFP28 SR optic on Dell PowerSwitch platforms. 407-BBXU appears on Dell.com as the matching customer-kit catalog code titled '25GbE SFP28 SR No FEC'; verify against your Dell quote or PowerSwitch compatibility documentation which SKU applies to your deployment. The module is programmed with Dell-recognized EEPROM vendor and part-number strings so PowerSwitch OS10 reads the optic cleanly through the standard SFP28 management interface.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber, with 10GBASE-SR support per IEEE 802.3ae on dual-rate SFP28 host ports. Line signaling rate is 10.3125 Gbps at 10GBASE-SR and 25.78125 Gbps at 25GBASE-SR. Reach is 100 m on OM4 and 70 m on OM3, within the SFP28 SerDes envelope defined by SFP28 MSA SFF-8402.

Optical path is 850 nm VCSEL transmitter, PIN photodiode receiver, TX optical power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget, LC duplex connector. Digital diagnostics are SFF-8472 Rev 12.0 compliant, exposing per-module temperature, supply voltage, TX bias, TX power and RX power through the PowerSwitch transceiver-diagnostics interface. Power dissipation is 0.3 W, the module is hot-swappable, and the operating temperature range is 0 to 70°C commercial.

Dell SFP28-25G-SR is positioned against Dell PowerSwitch S-series platforms with 25G SFP28 interfaces, the S5x00F-ON range, and Dell PowerEdge servers configured with SFP28 NIC ports. Verify Dell SFP28-25G-SR against the Dell PowerSwitch transceiver compatibility documentation for your specific PowerSwitch model and OS10 release before specifying the part. Dell's catalog also lists SFP28-25G-SR-G2 and SFP28-25G-SR-NOF as adjacent ordering codes in the same SFP28 SR family; match the SKU to your Dell quote or BOM.

On FEC, 25G FEC mode is configured at the MAC layer on each link partner and the optical path is agnostic to whether RS-FEC per IEEE 802.3by Clause 108 or BASE-R FEC is negotiated on the host. The PowerSwitch OS10 host FEC profile determines the negotiated mode on the link; confirm the FEC profile on both link partners during commissioning per the Dell PowerSwitch OS10 documentation for your firmware version. The module is symmetrically compatible with either FEC mode supported on the host port.
