Intel compatible E25GSFP28SR Description
EdgeOptic's E25GSFP28SR compatible is an Intel-coded 25GBASE-SR SFP28 transceiver, a direct replacement for Intel's E25GSFP28SR Ethernet SFP28 optic. It ships with Intel-recognized EEPROM for validation against the Intel i40e and ice drivers' module-identification policy on the XXV710 and E810 NIC families. E25GSFP28SR is Intel's own part number for the 850nm short-range SFP28 optic shipped for the XXV710-DA1 (single-port) and XXV710-DA2 (dual-port) 25 Gigabit Ethernet adapters.
Optical performance follows IEEE 802.3by Clause 112: 100m on OM4 or OM5 multimode fiber, 70m on OM3. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, with a 5.3 dB link budget using host RS-FEC (IEEE 802.3by Clause 108). The module uses an 850nm VCSEL transmitter, a PIN photodiode receiver, and an LC/UPC duplex connector. DOM telemetry is exposed per SFF-8472. Line rate is 8.5 to 25.78 Gbps. The module is dual-rate and operates at 10GBASE-SR (IEEE 802.3ae) as well as 25GBASE-SR, matching the XXV710's supported port speeds. Power consumption is 0.3W maximum over the 0 to 70°C case temperature range.
The E25GSFP28SR is positioned as the SFP28 optic for Intel's 25G server NIC line rather than a datacenter switch port. Platform scope at the adapter-family level: Intel Ethernet Network Adapter XXV710-DA1 (single-port), XXV710-DA2 (dual-port), and the Intel Ethernet Converged Network Adapter XXV710 cards that share the 700-Series controller. Driver support on the host covers Linux via the i40e kernel driver on RHEL, SUSE and Ubuntu, Windows via the Intel-signed driver package, FreeBSD, and VMware ESXi. Newer E810 800-Series adapters that fall back to 25G-optic use are driven by the ice driver.
Intel's 700-Series and 800-Series NICs enforce module validation at the driver and firmware level rather than at an EEPROM-lock layer. Intel's own i40e driver documentation states that some adapters based on the Ethernet Controller 700 Series only support Intel Ethernet Optics. The specific behaviour depends on the NIC sub-SKU, the firmware version and the driver release. EdgeOptic's Intel-recognized EEPROM coding is the mitigation at the module-identification layer for XXV710-DA1 and XXV710-DA2; for E810-based adapters, confirm driver and NVM firmware compatibility against the Intel NIC documentation for the specific adapter model before large-scale deployment.
DOM parameters (transmit power, receive power, temperature, laser bias, supply voltage) are accessible through the standard SFP28-port telemetry surfaces the Intel driver exposes via ethtool on Linux and the Intel NIC management path on Windows. 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 Intel XXV710 open-optic, and does EdgeOptic's E25GSFP28SR compatible work on every XXV710 sub-SKU?
The XXV710 is generally marketed as an open-optic NIC and the i40e driver accepts third-party SFP28 modules on most XXV710-DA1 and XXV710-DA2 configurations. Intel's own i40e driver documentation notes, however, that some adapters based on the Ethernet Controller 700 Series only support Intel Ethernet Optics. The precise behaviour depends on NIC sub-SKU, NIC firmware version and driver release. EdgeOptic codes the E25GSFP28SR compatible with Intel-recognized EEPROM, which is the right mitigation at the module-identification layer. For production deployments across large XXV710 fleets, verify module behaviour against a representative adapter with the target driver and firmware build before fleet rollout.
Does the E25GSFP28SR compatible operate at 10G as well as 25G on the XXV710?
Yes. The module is dual-rate and supports both 25GBASE-SR (IEEE 802.3by) and 10GBASE-SR (IEEE 802.3ae). SFP28 port speed on the XXV710 is driver-managed rather than in-band auto-negotiated. The i40e driver supports both 10G and 25G operation on the same SFP28 port, and active port speed is selected at the driver configuration layer or through NIC management tools to match the link partner's capability. That covers the common server-refresh path where a server-side 25G NIC is staged into an environment that still runs 10G top-of-rack.
Will the E25GSFP28SR compatible work on E810-based NICs with the ice driver?
The E25GSFP28SR is validated primarily against the XXV710 family on the i40e driver. E810 NICs use the ice driver, and module-identification behaviour on E810 depends on NIC NVM firmware version and the ice driver release on the host. For E810 deployments, confirm module compatibility against the Intel NIC documentation and NVM image revision for the specific E810 model before production use; contact sales for deployment-specific validation if the adapter list includes E810-C or E810-XXV sub-SKUs.
What is the E25GSFP28SR's 25GBASE-SR link budget and fiber reach?
Link budget is 5.3 dB with host RS-FEC (IEEE 802.3by Clause 108). Reach is 100m on OM4 or OM5, 70m on OM3. Transmit power -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, 850nm VCSEL over LC/UPC duplex. That envelope covers in-rack server-to-switch 25G links and short inter-rack runs on existing MMF plant. Spans beyond 100m require the 25G LR SFP28 family, which is a different optical module.
