Intel compatible LTF8505-BC-IN Description
EdgeOptic's LTF8505-BC-IN compatible is an Intel-coded 25GBASE-SR SFP28 transceiver, a direct replacement for Intel's E25GSFP28SR (LTF8505-BC-IN) optic. It ships with Intel-recognized EEPROM, so the module presents as a native Intel optic on XXV710 and E810 NICs under the Intel driver's module-identification check.
Optical specs match the Intel OEM: 850nm VCSEL, duplex MMF via LC/UPC, 100m reach on OM4/OM5 and 70m on OM3. Transmit power -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, 5.3 dB link budget with RS-FEC active per IEEE 802.3by Clause 108. Electrical side is SFF-8431 / SFF-8432 compliant, and the module supports 10GBASE-SR and 25GBASE-SR line rates (8.5 to 25.78 Gbps). Power draw is 0.3W maximum.
Target platforms are Intel server-side 25G NICs: Intel Ethernet Converged Network Adapter XXV710 (DA1 and DA2 variants), Intel E810-XXVDA2, and E810-XXVAM2. Supermicro's Intel-silicon AOC cards, AOC-S25G-I2S (XXV710) and AOC-A25G-I2SM (E810-XXVAM2), fall in the same Intel-silicon ecosystem and accept Intel-coded SFP28 optics. For Mellanox ConnectX silicon, the correct part number is MMA2P00-AS, a separate EdgeOptic SKU.
The LTF8505-BC-IN is the same physical transceiver as the Hisense LTF8505-BC+. Intel sources the module from Hisense Broadband and codes the EEPROM for Intel NIC validation, then sells it as E25GSFP28SR. Optical performance is identical between the two part numbers, but on hosts that enforce EEPROM validation they are not interchangeable. For Hisense-branded switch platforms, specify LTF8505-BC+.
One E810 firmware note worth planning for: Intel NVM firmware below revision 4.20 has documented 25G optical link-up issues on the E810 family, independent of the optic. Intel's community forum discussions identify the firmware update as the fix, not the transceiver. Intel-coded EEPROM removes the 'uncertified module' variable; keeping NVM at 4.20 or later removes the remaining link-stability variable. XXV710-series NICs are not affected by this specific E810 firmware caveat.
DOM values (transmit power, receive power, temperature, laser bias, supply voltage) are readable via the Intel NIC driver: `ethtool -m <if>` on Linux, or Intel's NIC diagnostic utilities on Windows Server. Operating temperature range is 0 to 70 degrees Celsius case (commercial). Every module is pre-tested on Intel XXV710 and E810 reference hardware before dispatch.

Frequently Asked Questions
Will the LTF8505-BC-IN trigger an 'uncertified module' warning on Intel E810 NICs?
No. EdgeOptic's LTF8505-BC-IN is programmed with Intel-recognized EEPROM data, so the E810 driver identifies the optic as Intel's E25GSFP28SR (the same module on Intel's validated optic list). The 'uncertified module' diagnostic does not appear. Separate from EEPROM validation, Intel E810 NVM firmware below revision 4.20 has documented 25G link-up issues regardless of optic; confirm NVM is 4.20 or later before deployment.
Is the LTF8505-BC-IN the same physical module as the Hisense LTF8505-BC+?
Yes, the same 850nm SFP28 transceiver manufactured by Hisense Broadband, with different EEPROM programming. LTF8505-BC-IN is coded for Intel NIC platforms and sold by Intel as E25GSFP28SR. LTF8505-BC+ is coded for Hisense-branded and Hisense-ecosystem switching hosts. Optical performance is identical, but the EEPROM targets different validation lists, so the two part numbers are not interchangeable on hosts that enforce module identification.
Does the LTF8505-BC-IN support dual-rate 10G and 25G operation on XXV710 and E810 NICs?
Yes. The module's SFP28 electrical interface supports 8.5 to 25.78 Gbps, which covers both 10GBASE-SR and 25GBASE-SR line rates. Set the Intel NIC port speed to match the link partner; RS-FEC is engaged at 25G and disabled at 10G per IEEE 802.3by. This is useful in mixed fleets where some servers still negotiate 10G uplinks during a phased 25G rollout on the same Intel NIC family.
Does the LTF8505-BC-IN pair with Supermicro Intel-silicon AOC cards?
Supermicro AOC cards built on Intel silicon (AOC-S25G-I2S on Intel XXV710, AOC-A25G-I2SM on Intel E810-XXVAM2) use the same Intel NIC driver stack and Intel-coded EEPROM validation as standalone Intel XXV710 and E810 NICs, so an Intel-coded LTF8505-BC-IN behaves the same way on those cards. For Supermicro AOC cards built on Mellanox silicon (AOC-S25G-m2S on ConnectX-4 Lx), the correct EdgeOptic part number is MMA2P00-AS. Confirm specific AOC card compatibility with us if your purchasing system requires vendor-signed compatibility statements.
