Intel compatible TXN31115D100000 Description

TXN31115D100000 is an Intel 10GBASE-SR SFP+ transceiver for Intel Ethernet network adapters. The module carries Intel-recognized EEPROM so X520, X710 and E810 series adapters accept the optic under stock ixgbe, i40e and ice driver stacks without the allow_unsupported_sfp override. TXN31115D100000 is a 10 Gigabit Ethernet module only and is not a multi-rate Fibre Channel part. The protocol is IEEE 802.3ae Clause 52 10GBASE-SR at 10.3125 Gbps, with maximum reach of 300 m over OM3 multimode fiber.

Qualified Intel host platforms include X520-DA2 and X520-SR2 dual-port 10GbE adapters, X710-DA2 and X710-DA4 10GbE SFP+ adapters, and E810-XXVDA2 dual-port 25GbE SFP28 adapters that back-rate to 10.3125 Gbps when paired with an SFP+ optic. Intel X540 and X550 are 10GBASE-T copper NICs with RJ45 cages and do not accept any SFP+ module; TXN31115D100000 will not operate on those part numbers. Optical build uses an 850 nm VCSEL transmitter and 850 nm PIN photodiode receiver, 6.1 dB minimum link budget, SFP+ MSA (SFF-8432) mechanical envelope with a duplex LC connector, and SFF-8472 DDM/DOM. Reach is 300 m over OM3 and 400 m over OM4, with 82 m over OM2 and 33 m over OM1 for legacy multimode runs.

DDM readings are exposed through ethtool -m on Linux and through Intel PROSet on Windows, so fleet monitoring scripts that already parse NIC-side optical telemetry continue to work unchanged. Typical deployment is server-to-ToR 10GbE uplinks inside a single data center hall over pre-installed OM3 or OM4 trunks, virtualization hosts with X710-DA2 adapters connecting to converged 10G/25G fabric switches, and E810-XXVDA2 hosts that run at 10G during transitional 10G-to-25G upgrades. Commercial operating range is 0 to 70 degrees Celsius. For lot-level Intel firmware qualification, rate-adaptive deployments on E810 adapters, or bulk ordering tied to specific X710 PBA revisions, please contact our sales team with the host adapter PBA list.

Frequently Asked Questions

Is TXN31115D100000 a Fibre Channel module or Ethernet only?

TXN31115D100000 is Ethernet only. It implements 10GBASE-SR per IEEE 802.3ae Clause 52 at 10.3125 Gbps with 300 m reach over OM3. It is not a multi-rate Fibre Channel optic and does not carry 8GFC or 4GFC framing.

Will TXN31115D100000 work on X520, X710 and E810 without the allow_unsupported_sfp flag?

Yes. The EEPROM carries the Intel-recognized vendor ID block, so ixgbe, i40e and ice drivers accept the optic under stock configuration. E810-XXVDA2 is a 25G SFP28 adapter and back-rates to 10.3125 Gbps when an SFP+ module is inserted.

Can TXN31115D100000 be used on Intel X540 or X550 adapters?

No. X540 and X550 are 10GBASE-T copper adapters with RJ45 cages. They have no SFP+ cage and do not accept any SFP+ optic. For Intel SFP+ hosts, use X520, X710, or E810 series adapters.
