Intel FTLX8574D3BCV-I3 Compatible 10G SFP+ SR Transceiver

Intel sells several variants of the Finisar-origin FTLX8574D3BCV transceiver under different suffixes, each targeting a specific deployment profile. The -I3 identifies the Intel OEM version with Intel-specific EEPROM coding, intended for Ethernet Server Adapters and Ethernet Converged Network Adapters in commercial-temperature environments (0 to 70 °C). A separate variant, the FTLX8574D3BCV-IT, carries industrial-temperature rating (-40 to 85 °C) and different firmware flags suited to outdoor cabinets, factory floors, and other high-ambient deployments. The base FTLX8574D3BCV without suffix is Finisar's own generic part, sold through distribution channels independently of Intel and without Intel-specific EEPROM coding. All three share the same 10GBASE-SR optical core, but their EEPROM vendor IDs differ, which matters during NIC firmware validation at link initialization. Selecting the correct suffix avoids driver warnings and reduced-link-speed fallback behavior.

EdgeOptic's compatible FTLX8574D3BCV-I3 matches the original optical specification: 850 nm VCSEL transmitter, LC duplex connector, minimum 6.1 dB link budget, rated for 300 m reach on OM3 multimode fiber or 400 m on OM4 and above. The module conforms to IEEE 802.3ae 10GBASE-SR and the SFF-8431/8432 SFP+ MSA. Data rate support ranges from 1.25 to 10.3125 Gbps, covering both Gigabit Ethernet and 10 Gigabit Ethernet operation in dual-rate mode. DDM (Digital Diagnostic Monitoring) provides real-time readouts of TX optical power, RX optical power, laser bias current, module temperature, and supply voltage through the standardized I2C interface.

The -I3 is typically deployed in Intel X710-DA2, XXV710-DA1, XL710-QDA1 (via QSFP-to-SFP+ breakout), and E810-XXVDA2 series adapters, all of which use SFP+ cages for 10GbE fiber uplinks in server and storage infrastructure. These adapters are common in VMware ESXi hosts, Hyper-V nodes, and bare-metal storage arrays where 10GbE multimode fiber connects the server to a top-of-rack switch. Intel's driver stack (ixgbe for X710-series, ice for E810-series) reads the transceiver EEPROM at link-up and reports vendor name, part number, and serial number through ethtool on Linux or Intel PROSet on Windows. EdgeOptic codes the EEPROM with Intel-recognized identifiers, so the adapter accepts the module without driver warnings or reduced-functionality mode. The X540-T2 and X550-T2 are copper 10GBASE-T adapters with RJ45 ports only and do not accept any SFP+ module.

The module is CE/RoHS certified and compliant with the SFF-8432 MSA standard. EdgeOptic tests each FTLX8574D3BCV-I3 unit against current Intel NIC firmware revisions during production. For questions about the -I3 vs -IT variant selection or specific NIC adapter compatibility, contact our sales team.
