Intel compatible FTLX8571D3BCV-IT Description
EdgeOptic's compatible FTLX8571D3BCV-IT is a replacement for the Intel Ethernet SFP+ SR Optics module, manufactured by Finisar (now Coherent) and distributed with Intel OEM EEPROM coding for Intel Ethernet adapters. The -IT suffix identifies this as the Intel OEM-coded version of the Finisar FTLX8571D3BCV base transceiver. It operates at 850 nm over multimode fiber, reaching 300 m on OM3 and 400 m on OM4, with a 6.1 dB optical budget.
The module is dual-rate, supporting both 1000BASE-SX (1.25 Gbps) and 10GBASE-SR (10.31 Gbps) operation. Data rates range from 1.25 to 10.31 Gbps, making it compatible with Gigabit Ethernet and 10G Ethernet ports. DDM/DOM diagnostics are supported per SFF-8472, providing real-time monitoring of optical power, temperature, and laser bias.
Intel lists the FTLX8571D3BCV-IT as a supported SFP+ for the X520-DA1, X520-DA2, X520-SR1, X520-SR2, and X710-DA2 Ethernet adapter families. Intel adapters by default restrict operation to Intel-recognized SFP+ modules. EdgeOptic codes the compatible FTLX8571D3BCV-IT with Intel-recognized EEPROM data so the adapter accepts it without driver-level workarounds.
Note that the -IT and -I3 suffixes denote different OEM EEPROM coding. FTLX8571D3BCV-IT is the Intel-branded OEM version, while FTLX8571D3BCV-I3 carries a different OEM coding. Both share the same base optical specifications (850 nm VCSEL, LC duplex, MMF), but the EEPROM vendor ID differs. The module conforms to IEEE 802.3ae, SFF-8431, and SFF-8432.
The module is CE/RoHS certified and compliant with the SFP+ MSA SFF-8432 standard. Operating temperature range is 0 to 70°C. For questions about the FTLX8571D3BCV-IT or Intel adapter compatibility, contact our sales team.
Frequently Asked Questions
Is the FTLX8571D3BCV-IT compatible with the Intel X520-DA2?
Yes. Intel lists the FTLX8571D3BCV-IT as a supported SFP+ for the X520-DA1, X520-DA2, X520-SR1, X520-SR2, and X710-DA2 adapters. EdgeOptic's compatible version is EEPROM-coded for Intel recognition, so the adapter accepts it without driver modifications.
What is the difference between FTLX8571D3BCV-IT and FTLX8571D3BCV-I3?
Both modules share the same base optical design (Finisar FTLX8571D3BCV, 850 nm 10GBASE-SR). The -IT suffix indicates Intel OEM EEPROM coding, while -I3 carries a different OEM vendor identifier. The optical specifications are identical; the difference is in the EEPROM data that identifies the module to the host platform.
Does the FTLX8571D3BCV-IT support dual-rate 1G and 10G operation?
Yes. The module supports data rates from 1.25 Gbps (1000BASE-SX) to 10.31 Gbps (10GBASE-SR). Actual speed depends on the host port configuration. In a 10G port it runs at 10.31 Gbps; in a 1G SFP port that accepts SFP+ modules, it negotiates at 1.25 Gbps.
