Intel LTF8505-BC-IN Compatible 25GBASE-SR SFP28 for XXV710 and E810

Intel-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver. The LTF8505-BC-IN compatible carries EEPROM programmed for Intel NIC validation on XXV710 and E810 platforms. Intel ships the same module under the retail SKU E25GSFP28SR; LTF8505-BC-IN and E25GSFP28SR identify the same Intel-coded 25GBASE-SR optic.

Optical specs match the Intel OEM: 850 nm VCSEL transmitter, PIN photodiode receiver, duplex MMF via LC/UPC, 100 m reach on OM4 and OM5 and 70 m on OM3. Transmit power −5 to +2.4 dBm, receive sensitivity better than −10.3 dBm, 5.3 dB link budget. RS-FEC per IEEE 802.3by Clause 91 (RS(528,514)) is enabled by the host port at 25G and disabled at 10G. Electrical interface is SFF-8431 / SFF-8432 compliant, and the module supports both 10GBASE-SR and 25GBASE-SR line rates (10.3 to 25.78 Gbps). Power draw is 0.3 W maximum across the 0 to 70 °C commercial operating range.

Works on Intel server-side 25G NICs in the XXV710 and E810 series. The Intel-coded EEPROM identifies the module on the Intel NIC driver's module-identification check, removing the 'uncertified module' diagnostic that appears with non-Intel-coded optics. Verify compatibility against Intel's adapter product brief or ARK for your specific XXV710 or E810 variant before deployment.

The LTF8505-BC-IN and the Hisense LTF8505-BC family share the LTF8505-BC base OPN with different EEPROM coding for different host classes. The -IN suffix designates Intel NIC validation; Hisense-branded ordering codes target different host platforms. On hosts that enforce EEPROM validation the part numbers are not interchangeable, so match the SKU to the target platform before ordering.

On E810 NICs, confirm a current NVM revision before deployment; consult Intel E810 NVM release notes for the applicable firmware version. Intel-coded EEPROM removes the 'uncertified module' variable; keeping NVM at a current revision removes the remaining link-stability variable. XXV710-series NICs use a different silicon and NVM architecture and are not subject to this E810-specific firmware caveat.

DOM values covering transmit power, receive power, temperature, laser bias, and supply voltage are readable via the Intel NIC driver on Linux and through Intel's NIC diagnostic utilities on Windows Server. Digital diagnostics are SFF-8472 compliant.
