Intel compatible FTLX1471D3BCVI31 Description
FTLX1471D3BCVI31 is an Intel-branded 10GBASE-LR SFP+ transceiver based on the Finisar FTLX1471D3BCV platform with an Intel-specific EEPROM suffix (I31). EdgeOptic's compatible replacement is built on our 10G-SFP-10 platform, matching the original optical and electrical specifications. The I31 suffix identifies this module as the Intel-coded variant manufactured by Finisar (now Coherent) specifically for the Intel Ethernet adapter ecosystem.
The FTLX1471D3BCV is Finisar's standard 10GBASE-LR SFP+, one of the most widely deployed LR modules in the industry. The "I31" suffix identifies a variant programmed with Intel vendor data in the EEPROM, enabling it to pass Intel NIC driver validation without generating unsupported-transceiver warnings. Intel's ixgbe driver (X520 family), i40e driver (X710/XXV710 family), and ice driver (E810 family) check the transceiver's vendor ID on link initialization, and the I31 coding satisfies that check. Without proper Intel vendor coding, newer driver versions may disable the SFP+ port entirely.
This part number is functionally equivalent to Intel's own-brand E10GSFPLR. Both are 10GBASE-LR, 1310 nm, 10 km modules for Intel Ethernet adapters. The difference is branding and supply chain: FTLX1471D3BCVI31 carries the Finisar/Coherent part number with an Intel suffix, while E10GSFPLR is Intel's catalog number manufactured by Intel's contracted optic suppliers. Server OEMs may list either part number in their hardware compatibility matrices depending on the adapter model and qualification date. HPE ProLiant servers commonly reference the FTLX variant in their QuickSpecs documents, while Dell PowerEdge documentation tends to list E10GSFPLR. Both part numbers produce identical driver behavior on Intel NICs and can be used interchangeably in the same adapter slot.
The transceiver uses a 1310 nm DFB laser transmitter and PIN photodiode receiver, conforming to IEEE 802.3ae 10GBASE-LR. Reach is 10 km over G.652 single-mode fiber with duplex LC/UPC connectors. DDM per SFF-8472 is accessible through ethtool on Linux, Intel PROSet on Windows, and esxcli on VMware ESXi. The SFP+ form factor conforms to SFF-8431/8432 mechanical and electrical standards.
Target adapters include Intel X520-DA2, X520-SR2, X710-DA2, X710-DA4, XXV710-DA2, and XL710-QDA2. EdgeOptic's compatible is coded with the Intel vendor identifier matching the I31 EEPROM profile.

Frequently Asked Questions
Is the FTLX1471D3BCVI31 the same module as the Intel E10GSFPLR?
Functionally, yes. Both are 10GBASE-LR 1310 nm SFP+ modules coded for Intel NICs. FTLX1471D3BCVI31 is a Finisar-origin part with Intel EEPROM coding (I31 suffix). E10GSFPLR is Intel's own catalog number. Either module works in the same Intel adapters with the same driver acceptance.
