Intel compatible E10GSFPT Description
EdgeOptic's Intel E10GSFPT compatible is an Intel-coded 10GBASE-T copper SFP+ transceiver for Intel Ethernet Server Adapters in the X520 family that ship with SFP+ cages. EdgeOptic programs the module EEPROM with Intel-recognised vendor identity for the X520 family, so the transceiver is presented as an Intel-branded module to the host NIC during EEPROM readback. The part is intended as a drop-in alternative to the native Intel E10GSFPT on equipment that carries the OEM SKU in its adapter documentation.
The transceiver operates per IEEE 802.3an for 10GBASE-T, IEEE 802.3bz for 2.5GBASE-T and 5GBASE-T, and IEEE 802.3ab for 1000BASE-T fallback. Reach is up to 30 m on Cat6a or Cat7 unshielded twisted-pair. The electrical and management interfaces follow SFF-8431 and SFF-8432, the governing MSAs for SFP+ class copper modules. Operating temperature covers 0 to 65 °C commercial grade, with CE and RoHS certification. The module draws more power than a fibre SFP+ and requires a high-power SFP+ cage, which Intel X520 Ethernet Server Adapters provide on their SFP+ slots.
Because the E10GSFPT is a copper module, DOM telemetry is scoped to the fields that apply to a non-optical SFP+: case temperature, supply voltage, and link status. There is no laser, so transmit optical power, receive optical power, and laser bias current do not exist on this part and are not reported. Management tooling that expects optical DDM values should be configured to treat this module as a copper transceiver.
Target adapters are the SFP+-caged variants of the Intel X520 Ethernet Server Adapter line: X520-SR2, X520-DA2, and X520-DA1. The X520-T2 is a separate variant with built-in 10GBASE-T RJ45 ports and no SFP+ cage; it does not use the E10GSFPT and should not be ordered for X520-T2 deployments. Under Linux, the X520 family runs on the ixgbe driver; under Windows Server, it runs on the Intel PROSet driver stack. The transceiver is not operating-system-specific — the host NIC handles SFP+ recognition at the driver layer regardless of OS.
The X710 and later Intel NIC generations use the i40e driver with a different SFP+ compatibility model; X710/i40e compatibility is out of scope for this page and should be verified separately against the current Intel Ethernet NIC documentation for the target adapter before deployment. For X520 deployments specifically, the ixgbe driver historically enforced an Intel allow-list on SFP+ EEPROM vendor IDs, which is the context for the FAQ guidance below — the EdgeOptic Intel-coded EEPROM presents the X520-recognised vendor identity, and behaviour for the running ixgbe release should be cross-checked against that release's notes before bringing the link into service.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical and copper SFP+ platforms. Ships next business day from EU stock with a lifetime warranty. For volume pricing, ixgbe driver release guidance, or Intel X520 adapter confirmation, contact our sales team.
Frequently Asked Questions
Does the Intel X520 ixgbe driver require the allow_unsupported_sfp parameter for third-party E10GSFPT compatibles?
Older ixgbe driver releases on Intel X520 adapters enforced an Intel-vendor allow-list for SFP+ modules and required the allow_unsupported_sfp=1 modprobe option to load non-Intel-coded transceivers. The enforced behaviour depends on the ixgbe driver version in use on the target host; consult the release notes for the specific ixgbe version (and, on Windows, the equivalent Intel PROSet release notes) to confirm whether the parameter is required in the target environment. Do not rely on behaviour from an older driver generation without verifying against the documentation for the current driver release on the host.
Is this page the correct compatible for Intel X710 adapters, which use the i40e driver?
No. The E10GSFPT is an Intel SFP+ SKU primarily associated with the X520 Ethernet Server Adapter family, which runs on the ixgbe driver. Intel X710 and later adapter generations use the i40e driver with a different SFP+ compatibility model, and transceiver validation on those platforms should be assessed against the current Intel Ethernet NIC documentation for the specific adapter. For X710 copper SFP+ deployments, verify compatibility separately before ordering.
Does the E10GSFPT work in the Intel X520-T2 adapter?
No. The X520-T2 is the dual-port 10GBASE-T variant of the X520 family with built-in RJ45 connectors and no SFP+ cages, so it does not accept any SFP+ transceiver. The E10GSFPT is for the SFP+-caged X520 variants only: X520-SR2, X520-DA2, and X520-DA1. If the target adapter is an X520-T2, no transceiver is required — the 10GBASE-T PHY is integrated.
