Intel compatible FTLX8571D3BCVI31 Description
EdgeOptic's FTLX8571D3BCVI31 compatible is an Intel-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. Intel-recognized EEPROM lets the optic register cleanly on Intel SFP+ network adapter cages, so the host accepts the module without a vendor-mismatch alert under Intel Ethernet drivers. One universal SR hardware platform, 80+ vendor codes, including this Intel-coded variant.
Optical specifications, 10GBASE-SR class. 850 nm VCSEL transmitter, PIN photodiode receiver, multi-mode duplex LC. Reach is 300 m on OM3 and 400 m on OM4. TX output power runs −5 to 0 dBm, receiver sensitivity −11.1 dBm, receiver overload 0 dBm, link budget 6.1 dB. Multi-rate capability spans 1.25 to 11.32 Gbps, covering 10G Ethernet, Gigabit Ethernet, 1G to 10G Fibre Channel, and STM-64. DDM/DOM supported for live link diagnostics. Compliance: SFF-8431, SFP MSA, IEEE 802.3ae, RoHS, IEC60825-1 Class 1 laser safety. Operating range 0 to 70°C commercial.
FTLX8571D3BCVI31 is the Intel-OEM-coded variant of the Finisar FTLX8571 10GBASE-SR SFP+ gen-1 family. The base FTLX8571 part is manufactured by Finisar (now part of Coherent following the II-VI 2019 acquisition and Coherent merger in 2022). The BCVI31 portion identifies this as an Intel OEM-coded variant on the base FTLX8571D3BCV. The I31 segment does not denote an industrial temperature grade; the optic operates at the standard commercial range, 0 to 70 degrees Celsius.
Designed for Intel SFP+ network adapters, including X520-DA2 on the 82599 chipset, X710-DA2 on the FM10000 chipset, XXV710 25G/10G adapters running at 10G, and E810-xxVDA adapters in 10G mode. The Intel Ethernet driver verifies the optic vendor identifier on these adapters; the BCVI31 coding maps to the Intel-recognized identifier the driver expects on these platforms. Intel X540 and X550 are 10GBASE-T copper NICs with RJ-45 ports and no SFP+ cages, so this SFP+ optic is not applicable to those adapters by physical port type.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty included.

FTLX8571D3BCVI31 FAQ
Will FTLX8571D3BCVI31 work in X520 and X710 adapters without additional configuration?
Yes. The Intel X520 (82599 chipset) and X710 (FM10000 chipset) SFP+ adapters verify the optic vendor identifier during driver load. EdgeOptic codes this compatible with the BCVI31 Intel-recognized EEPROM identifier, so the adapter accepts the optic and lists it under the normal Intel SFP+ inventory without an 'unsupported SFP+' warning. Verify against the Intel Ethernet Adapter User Guide for the driver release in use; vendor identifier support evolves across driver versions.
Does the -I31 suffix mean the optic is different from the standard FTLX8571D3BCV?
The optical specifications match the base FTLX8571D3BCV: 850 nm VCSEL, 300 m on OM3 / 400 m on OM4, LC duplex, multi-rate 1G to 10G envelope. The -I31 portion is the Intel platform revision segment of the Intel-OEM-coded variant; together with the BCVI prefix it identifies the Intel-coded EEPROM programming that Intel SFP+ adapter drivers expect to see during vendor identifier verification. The physical optic and the optical envelope are unchanged from the base FTLX8571D3BCV; the suffix affects EEPROM coding, not the optical layer.
Can I use this optic in an Intel X540 or X550 adapter?
No, and the reason is a physical port-type mismatch rather than a coding issue. The Intel X540 and X550 are 10GBASE-T copper Ethernet adapters built around RJ-45 copper ports; they do not have SFP+ cages and physically cannot accept an SFP+ transceiver. FTLX8571D3BCVI31 is an SFP+ optical module for fiber, so it does not connect to a BASE-T copper adapter regardless of EEPROM coding. For 10G fiber connectivity, use Intel SFP+ adapters such as X520-DA2, X710-DA2, XXV710, or E810-xxVDA, which expose SFP+ cages and accept this optic.
