Intel compatible FTLX8571D3BCV-I3 Description
FTLX8571D3BCV-I3 is an Intel-coded 10GBASE-SR SFP+ module, originally manufactured by Finisar (now II-VI/Coherent) and branded for Intel Ethernet adapters. The -I3 and -IT suffixes carry different EEPROM vendor data fields: both are OEM derivatives of the Finisar FTLX8571D3BCV, but they carry different EEPROM vendor ID fields. Intel NICs with different firmware revisions may expect one specific suffix. EdgeOptic's compatible version matches the -I3 coding exactly, so the adapter recognizes it as a factory-qualified optic.
Built on the 10G-SFP-300 platform, this module transmits at 850 nm using a VCSEL laser and receives with a PIN photodiode. Minimum optical power budget is 6.1 dB, supporting 300 m over OM3 and 400 m over OM4 multimode fiber. The LC/UPC duplex interface conforms to SFF-8431 and SFF-8432 mechanical and electrical standards. DDM provides real-time monitoring of optical power levels, temperature, laser bias current, and supply voltage through the I2C management interface accessible by the host NIC driver.
The chipset handles data rates from 1.25 to 10.3125 Gbps and is qualified for Intel X520, X710, and XXV710 adapter families running 10GBASE-SR (IEEE 802.3ae).Actual negotiated speed depends on the host adapter driver configuration and NIC firmware version, not the transceiver. In VMware ESXi or Linux bonding setups with Intel 10G NICs, the module operates transparently as a standard SFP+ SR optic.
Operating range is 0 to 70 °C commercial temperature. CE and RoHS certified, MSA-compliant per SFF-8432. Intel NIC firmware acceptance is confirmed on every module. EdgeOptic tests the FTLX8571D3BCV-I3 compatible against current Intel adapter firmware. For bulk pricing or adapter compatibility questions, contact our sales team.
Frequently Asked Questions
What is the difference between FTLX8571D3BCV-I3 and FTLX8571D3BCV-IT?
Both are Intel OEM variants of the Finisar FTLX8571D3BCV with identical optical specifications (850 nm, 10GBASE-SR, 300 m OM3). The difference is in the EEPROM vendor ID and sub-vendor fields. Some Intel NIC firmware revisions accept only the -IT coding, others only the -I3. Check the part number on your current transceiver or the Intel adapter's qualified optics list to confirm which suffix your setup requires.
Which Intel NICs support the FTLX8571D3BCV-I3?
The -I3 suffix appears in qualified optics lists for Intel X520-DA2, and X710-DA2 adapters, among others. Compatibility depends on the adapter firmware version. EdgeOptic programs the EEPROM to match the original Intel -I3 vendor coding, so the NIC recognizes it as a factory-qualified optic.
