Intel compatible E10GSFPLR Description
E10GSFPLR is Intel's part number for a 10GBASE-LR SFP+ optical transceiver designed for Intel Ethernet server adapters. EdgeOptic's compatible replacement is built on our 10G-SFP-10 platform, matching the original optical and electrical specifications. Intel Ethernet adapters are the dominant 10G NIC platform in x86 server environments, making E10GSFPLR one of the highest-volume server optic part numbers in the market.
E10GSFPLR is qualified for the Intel X520-DA2, X520-SR2, X710-DA2, X710-DA4, XXV710-DA2, and XL710-QDA2 adapter families. These NICs ship as standard options in Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro server lines. Intel's NIC driver (ixgbe for X520, i40e for X710/XXV710, ice for E810) reads the transceiver EEPROM on link initialization and validates the vendor ID. Modules that lack Intel-recognized vendor coding may be rejected by default, with the port remaining down unless the administrator sets the allow_unsupported_sfp kernel parameter on Linux or modifies the Windows driver settings. Intel enforces this validation more strictly with each driver generation, making proper vendor coding increasingly important for production server deployments.
The transceiver uses a 1310 nm DFB laser transmitter and PIN photodiode receiver, conforming to IEEE 802.3ae 10GBASE-LR. Link reach is 10 km over G.652 single-mode fiber with duplex LC/UPC connectors. DDM per SFF-8472 reports optical power (Tx and Rx), temperature, bias current, and voltage. The SFP+ form factor follows SFF-8431/8432 mechanical and electrical specifications.
In data center deployments, E10GSFPLR connects servers to top-of-rack or end-of-row switches over single-mode fiber. The 10 km LR reach is often selected for cross-campus or inter-building server-to-storage links where SR modules (limited to 300 m on OM3) fall short. Intel NIC drivers expose DDM readings through ethtool on Linux and Intel PROSet on Windows, enabling integration with IPMI, Redfish, and out-of-band management frameworks for proactive optic health monitoring. In VMware ESXi environments, the same DDM data is accessible through esxcli network nic commands. Storage administrators running iSCSI or NFS over 10GbE also use E10GSFPLR for long-distance server-to-NAS and SAN-over-IP connectivity where the 300 m SR reach is insufficient.
EdgeOptic's compatible is programmed with an Intel-recognized vendor identifier, so the NIC accepts it without driver workarounds. For server refresh projects, NIC-optic bundling, or hypervisor-qualified optic requirements, contact our sales team
Frequently Asked Questions
Will the E10GSFPLR trigger an unsupported-transceiver warning on Intel X520 or X710?
Intel's ixgbe and i40e drivers check the transceiver EEPROM vendor field. EdgeOptic's compatible is coded with an Intel-recognized identifier, so the NIC accepts it without the allow_unsupported_sfp kernel parameter. If a third-party optic lacks proper coding, the driver may disable the port by default on newer kernel versions.
Does the E10GSFPLR work in non-Intel NICs like Mellanox or Broadcom?
E10GSFPLR is an Intel part number, but the underlying optics follow standard 10GBASE-LR IEEE 802.3ae specifications. EdgeOptic's compatible works in any SFP+ port that accepts 10GBASE-LR, regardless of NIC vendor. The Intel-specific coding is only relevant for Intel driver validation.
Can the E10GSFPLR be used with Intel X710-DA2 in SR-IOV or DPDK configurations?
Yes. The transceiver operates at the physical layer and has no interaction with SR-IOV virtual function assignment or DPDK poll-mode drivers. Those are NIC firmware and software features. Any 10GBASE-LR SFP+ that links at 10G will support SR-IOV and DPDK on the X710 platform.
Is the E10GSFPLR the same module as the FTLX1471D3BCVI31?
FTLX1471D3BCVI31 is another Intel-qualified 10GBASE-LR SFP+ with a Finisar-origin part number and an Intel "I31" suffix. Both are 10GBASE-LR 1310 nm modules for Intel NICs. E10GSFPLR is Intel's own-brand part number; FTLX1471D3BCVI31 is the Finisar/Coherent-branded equivalent with Intel coding.
